The anatomy and physiology of the omentum provide optimum reconstructive characteristics and the omentum may be used as a free or pedicled autograft, but also as the receptor site for engraftment of glandular islets. Our purpose was the study of the omental anatomy of non-human primate (NHP), in order to determine an experimental model for pancreatic islets transplantation. Seventeen cadavers NHP (age range 4 years to 23 years) were utilised in this anatomical study. Both cynomolgus monkeys (macaca fascicularis) and baboons (papio hamadryas) were analysed. The animals were without known medical or anatomical abnormalities. We studied the morphology of the omentum, with an emphasis on arterial vascularisation. The omental anatomy of the NHP is very similar to that of humans. The main difference lies in the shape of the lesser sac, which has a complete caudal recess. The arterial vascularisation has a double origin. Based on the anastomosis between them and on the vascular density, the NHP omentum can be divided into four vascular areas. Our results demonstrate that one or two long pedicled flaps can be constructed from the omentum.

As we know, the human brain is one of the most complicated organs in the human body, which is the key and difficult point in neuroanatomy and sectional anatomy teaching. With the rapid development and extensive application of imaging technology in clinical diagnosis, doctors are facing higher and higher requirement on their anatomy knowledge. Thus, to cultivate medical students to meet the needs of medical development today and to improve their ability to read and understand radiographic images have become urgent challenges for the medical teachers. In this context, we developed a digital interactive human brain atlas based on the Chinese visible human datasets for anatomy teaching (available for free download from http://www.chinesevisiblehuman.com/down/DHBA.rar). The atlas simultaneously provides views in all 3 primary planes of section. The main structures of the human brain have been anatomically labeled in all 3 views. It is potentially useful for anatomy browsing, user self-testing, and automatic student assessment. In a word, it is interactive, 3D, user friendly, and free of charge, which can provide a new, intuitive means for anatomy teaching.

Virtual reality anatomy: is it comparable with traditional methods in the teaching of human forearm musculoskeletal anatomy?

PubMed

Codd, Anthony M; Choudhury, Bipasha

2011-01-01

The use of cadavers to teach anatomy is well established, but limitations with this approach have led to the introduction of alternative teaching methods. One such method is the use of three-dimensional virtual reality computer models. An interactive, three-dimensional computer model of human forearm anterior compartment musculoskeletal anatomy was produced using the open source 3D imaging program "Blender." The aim was to evaluate the use of 3D virtual reality when compared with traditional anatomy teaching methods. Three groups were identified from the University of Manchester second year Human Anatomy Research Skills Module class: a "control" group (no prior knowledge of forearm anatomy), a "traditional methods" group (taught using dissection and textbooks), and a "model" group (taught solely using e-resource). The groups were assessed on anatomy of the forearm by a ten question practical examination. ANOVA analysis showed the model group mean test score to be significantly higher than the control group (mean 7.25 vs. 1.46, P < 0.001) and not significantly different to the traditional methods group (mean 6.87, P > 0.5). Feedback from all users of the e-resource was positive. Virtual reality anatomy learning can be used to compliment traditional teaching methods effectively.

Visualization of human anatomy in a 3D atlas requires both spatial and more abstract symbolic knowledge. Within our 'intelligent volume' model which integrates these two levels, we developed and implemented a semantic network model for describing human anatomy. Concepts for structuring (abstraction levels, domains, views, generic and case-specific modeling, inheritance) are introduced. Model, tools for generation and exploration and applications in our 3D anatomical atlas are presented and discussed.

Near-peer teaching (NPT) is a strategy in which senior students assume the instructor role with junior peers (mentees). Senior students develop unique skills and knowledge through NPT, an experience which extends their learning beyond content mastery. Different teaching modules featuring NPT were utilized in the human anatomy course at the School of Medicine, Autonomous University of Nuevo Leon in Monterrey, Mexico. Modules included: Theory, Clinical Hour, Imaging Anatomy, and Laboratory. The aim of this study was to assess instructor participants' perceptions on the benefits of the NPT strategy in the anatomy classroom. A survey was administered to anatomy course instructors who utilized NPT strategies during winter, fall, and spring semesters of the 2012-2013 school year. A total of 120 instructors were enrolled in the study. There were different perceptions of instructors' roles. Theory and Imaging Anatomy instructors considered themselves to be information providers and resource developers, whereas Clinical Hour and Laboratory instructors saw themselves more as facilitators, role models, and planners. All instructors' opinions on the benefits of NPT were positive. Thus, in this article, the authors find NPT to be a strategy that promotes self-learning, a vital skill. © 2014 American Association of Anatomists.

The assessment of virtual reality for human anatomy instruction

Benn, Karen P.

1994-01-01

This research project seeks to meet the objective of science training by developing, assessing, and validating virtual reality as a human anatomy training medium. In ideal situations, anatomic models, computer-based instruction, and cadaver dissection are utilized to augment the traditional methods of instruction. At many institutions, lack of financial resources limits anatomy instruction to textbooks and lectures. However, human anatomy is three dimensional, unlike the one dimensional depiction found in textbooks and the two dimensional depiction found on the computer. Virtual reality is a breakthrough technology that allows one to step through the computer screen into a three dimensional world. This technology offers many opportunities to enhance science education. Therefore, a virtual testing environment of the abdominopelvic region of a human cadaver was created to study the placement of body parts within the nine anatomical divisions of the abdominopelvic region and the four abdominal quadrants.

Cat dissection and human cadaver prosection versus sculpting human structures from clay: A comparison of alternate approaches to human anatomy laboratory education

NASA Astrophysics Data System (ADS)

Waters, John R.

Dissection and vivisection are traditional approaches to biology laboratory education. In the case of human anatomy teaching laboratories, there is a long tradition of using human and animal cadaver specimens in the classroom. In a review of the literature comparing traditional dissection and vivisection lessons to alternative lessons designed to reduce the time spent dissecting or the numbers of animals used, we conclude that it is difficult to come to any conclusion regarding the efficacy of different approaches. An analysis of the literature is confounded because many studies have very low statistical power or other methodological weaknesses, and investigators rely on a wide variety of testing instruments to measure an equally varied number of course objectives. Additional well designed studies are necessary before educators can reach any informed conclusions about the efficacy of traditional versus alternative approaches to laboratory education. In our experiments, we compared a traditional cat dissection based undergraduate human anatomy lesson to an alternative where students sculpted human muscles onto plastic human skeletons. Students in the alternative treatment performed significantly better than their peers in the traditional treatment when answering both lower and higher order human anatomy questions. In a subsequent experiment with a similar design, we concluded that the superior performance of the students in the alternative treatment on anatomy exams was likely due to the similarity between the human anatomy representation studied in lab, and the human anatomy questions asked on the exams. When the anatomy questions were presented in the context of a cat specimen, students in the traditional cat dissection treatment outperformed their peers in the alternative treatment. In a final experiment where student performance on a human anatomy exam was compared between a traditional prosected human cadaver treatment and the alternative clay sculpting

1996-01-01

This research project seeks to meet the objective of science training by developing, assessing, validating and utilizing VR as a human anatomy training medium. Current anatomy instruction is primarily in the form of lectures and usage of textbooks. In ideal situations, anatomic models, computer-based instruction, and cadaver dissection are utilized to augment traditional methods of instruction. At many institutions, lack of financial resources limits anatomy instruction to textbooks and lectures. However, human anatomy is three-dimensional, unlike the one-dimensional depiction found in textbooks and the two-dimensional depiction found on the computer. Virtual reality allows one to step through the computer screen into a 3-D artificial world. The primary objective of this project is to produce a virtual reality application of the abdominopelvic region of a human cadaver that can be taken back to the classroom. The hypothesis is that an immersive learning environment affords quicker anatomic recognition and orientation and a greater level of retention in human anatomy instruction. The goal is to augment not replace traditional modes of instruction.

To address the need for more clinical anatomy training in residency education, many postgraduate programs have implemented structured anatomy courses into their curriculum. Consensus often does not exist on specific content and level of detail of the content that should be included in such curricula. This article describes the use of the Delphi method to identify clinically relevant content to incorporate in a musculoskeletal anatomy curriculum for Physical Medicine and Rehabilitation (PM&R) residents. A two round modified Delphi involving PM&R experts was used to establish the curricular content. The anatomical structures and clinical conditions presented to the expert group were compiled using multiple sources: clinical musculoskeletal anatomy cases from the PM&R residency program at the University of Toronto; consultation with PM&R experts; and textbooks. In each round, experts rated the importance of each curricular item to PM&R residency education using a five-point Likert scale. Internal consistency (Cronbach's alpha) was used to determine consensus at the end of each round and agreement scores were used as an outcome measure to determine the content to include in the curriculum. The overall internal consistency in both rounds was 0.99. A total of 37 physiatrists from across Canada participated and the overall response rate over two rounds was 97%. The initial curricular list consisted of 361 items. After the second iteration, the list was reduced by 44%. By using a national consensus method we were able to objectively determine the relevant anatomical structures and clinical musculoskeletal conditions important in daily PM&R practice. © 2013 American Association of Anatomists.

The human anatomy, or in brief, the body structure has fascinated man for ages. Due to the information explosion and the increase in specializations, this knowledge is available in a very sketchy manner in high school biology courses. The first comprehensive course on the human anatomy is taught to the first year medical students in medical colleges. This is in keeping with the regulations of the Medical Council of India. The anatomy lecture classes occupy a considerable time of the course, to provide the students with an effective knowledge of the gross anatomy, histology, embryology and the clinical anatomy. On the other hand, the students' feedback regarding the lecture methods and the teaching environment is crucial in judging the efficacy of the present curriculum. To obtain the students' feedback about the environment of the lecture classes, as regards the venue, the teaching and learning aids which are used, the lecture class schedule of the university (the number of classes per week, the durations of the lecture classes, etc.) and the existing departmental practices (display of the class routine in advance, synchronization between the lecture and the practical classes), so that their suggestions could help the faculty in planning the most effective teaching procedures. A semi structured questionnaire was supplied to the students to get their feedback. Most of the students found the air conditioned seminar room's environment to be more comfortable and they supported the existing durations of the lecture hours with the combined use of chalk and a board and overhead projectors (OHPs). The perceptions of the learners helped in modifying the departmental practice in the desired way.

To evaluate the overall effectiveness of a human anatomy course taught to distance-based and campus-based pharmacy students. A retrospective analysis of students' grades and course evaluations from 2003 through 2006 was conducted. No significant differences in student performance by pathway were found for the 2003-2005 academic years (p > 0.05). However, distance-based students' percentage and letter grades were significantly higher in 2006 (p = 0.013 and p = 0.004 respectively). Comparison of course and instructor evaluations showed that students in the distance course held similar or more positive perceptions of the course than their campus peers. Similar performance by campus and distance students enrolled in a human anatomy suggests that a distance-based course can be used successfully to teach human anatomy to pharmacy students.

Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face-to-face teaching in gross anatomy courses. While face-to-face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second-year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P < 0.001) but was also mediated by engagement with LMS videos and discussion forums (P < 0.001). Student learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content.

Gross anatomy is taught in medical school with textbooks, cadaver dissection, plastic models, and multimedia illustration, but all lack the reality of color and texture that is possible with fresh tissue dissection. The authors studied the use of fresh tissue dissection of the thorax and abdomen of the rat to teach human anatomy. In a half-day exercise, 52 fourth-year medical students paired off and completed an exercise to dissect in less than three hours the thorax and abdomen of a euthanized rat. Observation of organs was augmented by active manipulation such as passing a tube down the esophagus, cannulating the trachea and inflating the lungs, injecting dye in the kidney to trace the ureter and bladder, and pulling the testis through the inguinal canal. Comparison of the rat and human was emphasized to enhance the education. The exercise ended with practice suturing fresh tissue. Students rated the exercise to teach anatomy as 4.9 positive on a 5.0 (high) scale. The significant positive structures (p <.05) for texture were heart, liver, lungs and trachea; for color they were lungs and spleen; for location and size they were adrenal gland and urinary bladder; and for function they were adrenal gland and esophagus. Fresh tissue dissection of the thorax and abdomen of the rat is a valuable tool for human anatomy education. The dissonances in human and rat anatomy enhance abstraction and transfer of knowledge. Active manipulation of organs promotes retention of knowledge, and suturing provides a "clinical" context. Fresh tissue dissection is an efficient innovative method to provide a global review of anatomy of the thorax and abdomen during the busy clinical years of medical education.

Quanti-chanwei (1881) is the first technical book on human anatomy written in Chinese and brought to Modern China. It was compiled and translated on the basis of Anatomy, Descriptive and Surgical (first edition in 1858) by Henry Gray. Quanti-chanwei was published with intent to establish Chinese translations for terms referring to anatomy, and it gained broad support from medical missionaries who mainly served in Guangdong, Shanghai, and Fuzhou at that time. Quanti-tongkao (1886) was also complied and translated on the basis of Gray' Anatomy, Descriptive and Surgical. It was published from Jingshi Tongwen Guan, The Academy of Foreign Languages in the Qing dynasty, and they selected different words for the translation into Chinese from Quanti-chanwei. Thus, although Gray' Anatomy, Descriptive and Surgical played a great role in the introduction of Western Medicine into Modern China, there was no accordance between the national government and the provinces regarding Chinese translations for terms referring to anatomy.

The city and University of Padua have a long tradition and a great reputation in anatomic studies, dating from the founding of the university in the year 1222. We present a historical review of the study of human anatomy, for which Padua was a most important center. The background for the development of this culture was represented by the scientific freedom and political wisdom of the Serenissima Republic of Venice, a liberal and tolerant state in the midst of a feudal, imperial, and pontifical Europe. During the second half of the 15th century, the flourishing trade and cultural, social, and political life of Venice attracted a great number of scientists and students from all over Europe who contributed to the establishment of Padua as an international center for culture and the sciences. Vesalio, Fabrizio d'Acquapendente, and Giovanni Battista Morgagni represent milestones in the history of anatomy as well as in medicine and surgery. History shows that anatomy and surgery evolved together, just as anatomy of the nervous system and neurosurgery developed in tandem. The tradition of neurosurgery in Padua is considered one the most important schools in Italy.

Anatomy and humanity: Examining the effects of a short documentary film and first anatomy laboratory experience on medical students.

Medical students begin their education inside a laboratory dissecting cadavers to learn human gross anatomy. Many schools use the course experience as a way to instill empathy and some have begun integrating video and recorded interviews with body donors to humanize the experience, but their impact has yet to be measured. This study examines the effects of a brief documentary film and the initial cadaver encounter on student perceptions and attitudes towards the laboratory experience. A pre-test, exposure, post-test design was used with 77 first-year medical students at the University of Central Florida. A previously validated questionnaire was adapted to measure attitudes, emotions, initial reaction to cadaver, perception of the donor as a person, and impressions of the film. An online questionnaire was completed before the first day of laboratory, in which students watched the film Anatomy and Humanity and handled their respective cadavers (no dissection was performed). The post-test was administered immediately following the activities of the first laboratory day. Results indicate an increase in negative attitudes towards dissection, but a more positive initial reaction to the cadaver than originally anticipated. Students also experienced a decrease in emotions like sadness and guilt regarding anatomy laboratory and were less likely to view the cadaver as a once-living person. Findings suggest a higher comfort level, but also greater detachment toward the cadavers from day one despite the video intervention. These results provide novel insight that may aid other interventions aimed at promoting humanism in the anatomy laboratory experience. © 2015 American Association of Anatomists.

The increasing number of digital anatomy teaching software packages challenges anatomy educators on how to best integrate these tools for teaching and learning. Realistically, there exists a complex interplay of design, implementation, politics, and learning needs in the development and integration of software for education, each of which may be further amplified by the somewhat siloed roles of programmers, faculty, and students. LINDSAY Presenter is newly designed software that permits faculty and students to model and manipulate three-dimensional anatomy presentations and images, while including embedded quizzes, links, and text-based content. A validated tool measuring impact across pedagogy, resources, interactivity, freedom, granularity, and factors outside the immediate learning event was used in conjunction with observation, field notes, and focus groups to critically examine the impact of attitudes and perceptions of all stakeholders in the early implementation of LINDSAY Presenter before and after a three-week trial period with the software. Results demonstrate that external, personal media usage, along with students' awareness of the need to apply anatomy to clinical professional situations drove expectations of LINDSAY Presenter. A focus on the software over learning, which can be expected during initial orientation, surprisingly remained after three weeks of use. The time-intensive investment required to create learning content is a detractor from user-generated content and may reflect the consumption nature of other forms of digital learning. Early excitement over new technologies needs to be tempered with clear understanding of what learning is afforded, and how these constructively support future application and integration into professional practice.

Chlorophyll plays a pivotal role in the plant physiology and its productivity. Cultivation of plants in crude oil contaminated soil has a great impact on the synthesis of chlorophyll pigment. Morpho-anatomy of the experimental plant also shows structural deformation in higher concentrations. Keeping this in mind, a laboratory investigation has been carried out to study the effect of crude oil on chlorophyll content and morpho-anatomy of Cyperus brevifolius plant. Fifteen-day-old seedling of the plant was planted in different concentrations of the crude oil mixed soil (i.e., 10,000, 20,000, 30,000, 40,000, and 50,000 ppm). A control setup was also maintained without adding crude oil. Results were recorded after 6 months of plantation. Investigation revealed that there is a great impact of crude oil contamination on chlorophyll content of the leaves of the experimental plant. It also showed that chlorophyll a, chlorophyll b, and total chlorophyll content of leaves grown in different concentrations of crude oil were found to be lower than those of the control plant. Further, results also demonstrated that chlorophyll content was lowest in the treatment that received maximum dose of crude oil. It also showed that chlorophyll content was decreased with increased concentration of crude oil. Results also demonstrated that there was a reduction in plant shoot and root biomass with the increase of crude oil concentration. Results also revealed that the shoot biomass is higher than root biomass. Morphology and anatomy of the experimental plant also show structural deformation in higher concentrations. Accumulation of crude oil on the cuticle of the transverse section of the leaves and shoot forms a thick dark layer. Estimation of the level of pollution in an environment due to oil spill is possible by the in-depth study of the harmful effects of oil on the morphology and anatomy and chlorophyll content of the plants grown in that particular environment.

To determine whether the quizzes had any effect on retention, they were given in a controlled setting to 21 future medical and dental students. The weekly quizzes included questions on regional anatomy and an expanded set of questions on the nervous system. Each question about the nervous system was given three times, in a slightly different form each time. The second quiz was given approximately half an hour after the first one, and the third was given one week after the second to assess retention. The quizzes were unpopular, but students showed robust improvement on the questions about the nervous system. The scores increased by almost 9% on the second quiz, with no intervention except viewing the correct answers. The scores were 29% higher on the third quiz than on the first, and there was also a positive correlation between the grades on the quizzes and the final examination. Thus, repeated testing is an effective strategy for learning and retaining information about human anatomy. Copyright © 2011 American Association of Anatomists.

Recent work in cognitive psychology has shown that repeatedly testing one’s knowledge is a powerful learning aid and provides substantial benefits for retention of the material. To apply this in a human anatomy course for medical students, 39 fill-in-the-blank quizzes of about 50 questions each, one for each region of the body and four about the nervous system, were developed. The quizzes were optional, and no credit was awarded. They were posted online using Blackboard, which provided feedback, and they were very popular.

The use of computers to teach human anatomy and physiology to allied health and nursing students

NASA Astrophysics Data System (ADS)

Bergeron, Valerie J.

Educational institutions are under tremendous pressure to adopt the newest technologies in order to prepare their students to meet the challenges of the twenty-first century. For the last twenty years huge amounts of money have been spent on computers, printers, software, multimedia projection equipment, and so forth. A reasonable question is, "Has it worked?" Has this infusion of resources, financial as well as human, resulted in improved learning? Are the students meeting the intended learning goals? Any attempt to develop answers to these questions should include examining the intended goals and exploring the effects of the changes on students and faculty. This project investigated the impact of a specific application of a computer program in a community college setting on students' attitudes and understanding of human anatomy and physiology. In this investigation two sites of the same community college with seemingly similar students populations, seven miles apart, used different laboratory activities to teach human anatomy and physiology. At one site nursing students were taught using traditional dissections and laboratory activities; at the other site two of the dissections, specifically cat and sheep pluck, were replaced with the A.D.A.M.RTM (Animated Dissection of Anatomy for Medicine) computer program. Analysis of the attitude data indicated that students at both sites were extremely positive about their laboratory experiences. Analysis of the content data indicated a statistically significant difference in performance between the two sites in two of the eight content areas that were studied. For both topics the students using the computer program scored higher. A detailed analysis of the surveys, interviews with faculty and students, examination of laboratory materials, and observations of laboratory facilities in both sites, and cost-benefit analysis led to the development of seven recommendations. The recommendations call for action at the level of the

Ontology-driven education: Teaching anatomy with intelligent 3D games on the web

NASA Astrophysics Data System (ADS)

Nilsen, Trond

Human anatomy is a challenging and intimidating subject whose understanding is essential to good medical practice, taught primarily using a combination of lectures and the dissection of human cadavers. Lectures are cheap and scalable, but do a poor job of teaching spatial understanding, whereas dissection lets students experience the body's interior first-hand, but is expensive, cannot be repeated, and is often imperfect. Educational games and online learning activities have the potential to supplement these teaching methods in a cheap and relatively effective way, but they are difficult for educators to customize for particular curricula and lack the tutoring support that human instructors provide. I present an approach to the creation of learning activities for anatomy called ontology-driven education, in which the Foundational Model of Anatomy, an ontological representation of knowledge about anatomy, is leveraged to generate educational content, model student knowledge, and support learning activities and games in a configurable web-based educational framework for anatomy.

Human cadavers Vs. multimedia simulation: A study of student learning in anatomy.

Saltarelli, Andrew J; Roseth, Cary J; Saltarelli, William A

2014-01-01

Multimedia and simulation programs are increasingly being used for anatomy instruction, yet it remains unclear how learning with these technologies compares with learning with actual human cadavers. Using a multilevel, quasi-experimental-control design, this study compared the effects of "Anatomy and Physiology Revealed" (APR) multimedia learning system with a traditional undergraduate human cadaver laboratory. APR is a model-based multimedia simulation tool that uses high-resolution pictures to construct a prosected cadaver. APR also provides animations showing the function of specific anatomical structures. Results showed that the human cadaver laboratory offered a significant advantage over the multimedia simulation program on cadaver-based measures of identification and explanatory knowledge. These findings reinforce concerns that incorporating multimedia simulation into anatomy instruction requires careful alignment between learning tasks and performance measures. Findings also imply that additional pedagogical strategies are needed to support transfer from simulated to real-world application of anatomical knowledge. © 2014 American Association of Anatomists.

This article describes a chart-based approach for health sciences libraries to compare anatomy e-resources. The features, functionalities, and user experiences of seven leading subscription-based e-resources were assessed using a chart that was iteratively developed by the investigators. Acland's Video Atlas of Human Anatomy, Thieme Winking Skull, and Visible Body were the preferred products as they respectively excel in cadaver-based videos, self-assessment, and 3D graphical manipulation. Moreover, each product affords a pleasant user experience. The investigative team found that resources specializing in one aspect of anatomy teaching are superior to those that contain a wealth of content for diverse audiences.

2014-01-01

Nowadays more and more modern medical degree programs focus on self-directed and problem-based learning. That requires students to search for high quality and easy to retrieve online resources. YouTube is an emerging platform for learning human anatomy due to easy access and being a free service. The purpose of this study is to make a quantitative and qualitative analysis of the available human heart anatomy videos on YouTube. Using the search engine of the platform we searched for relevant videos using various keywords. Videos with irrelevant content, animal tissue, non-English language, no sound, duplicates, and physiology focused were excluded from further elaboration. The initial search retrieved 55,525 videos, whereas only 294 qualified for further analysis. A unique scoring system was used to assess the anatomical quality and details, general quality, and the general data for each video. Our results indicate that the human heart anatomy videos available on YouTube conveyed our anatomical criteria poorly, whereas the general quality scoring found borderline. Students should be selective when looking up on public video databases as it can prove challenging, time consuming, and the anatomical information may be misleading due to absence of content review. Anatomists and institutions are encouraged to prepare and endorse good quality material and make them available online for the students. The scoring rubric used in the study comprises a valuable tool to faculty members for quality evaluation of heart anatomy videos available on social media platforms.

Student performance in and perceptions of a high structure undergraduate human anatomy course.

PubMed

Shaffer, Justin F

2016-11-01

Human anatomy has usually been taught in a didactic fashion in colleges and universities. However, recent calls from United States governmental agencies have called for the transformation of undergraduate life sciences education to include active learning in the classroom. In addition, high structure courses have been shown to increase student engagement both in and out of the classroom and to improve student performance. Due to these reform efforts and the evidence on the benefits of these student-centered pedagogies, the goal of this study was to develop and assess a high structure college undergraduate human anatomy course with a lecture and laboratory component. The course was taught using a systems anatomy approach that required students to read the textbook and complete assignments before class, actively participate in class, and complete review quizzes after class. Results showed that teaching with high structure methods did not negatively affect any student groups (based on gender, ethnicity, or major) as measured by performance on lecture examinations and laboratory practical examinations. Students reported that reading the textbook and working with anatomical models were the most important towards helping them learn the course material and students' confidence in achieving the course goals significantly increased at the end of the course. The successful development and implementation of this course suggests that it is possible to teach human anatomy using active learning and high structure. Future studies can now be conducted to determine the contributions of specific course components to student success in high structure human anatomy courses.

Harrell, Leigh S.

The purpose of this study was two-fold. First the study was designed to determine student perceptions regarding the perceived degree of original learning from a human anatomy and physiology course, and the student perception of the use of the knowledge in an allied health program. Second, the intention of the study was to establish student beliefs on the characteristics of the transfer of learning including those factors which enhance learning transfer and those that serve as barriers to learning transfer. The study participants were those students enrolled in any allied health program at a community college in a Midwest state, including: nursing, radiology, surgical technology, health information technology, and paramedic. Both quantitative and qualitative data were collected and analyzed from the responses to the survey. A sub-group of participants were chosen to participate in semi-structured formal interviews. From the interviews, additional qualitative data were gathered. The data collected through the study demonstrated student perception of successful transfer experiences. The students in the study were able to provide specific examples of learning transfer experienced from the human anatomy and physiology course in their allied health program. Findings also suggested students who earned higher grades in the human anatomy and physiology course perceived greater understanding and greater use of the course's learning objectives in their allied health program. The study found the students believed the following learning activities enhances the transfer of learning: (1) Providing application of the information or skills being learned during the instruction of the course content enhances the transfer of learning. (2) Providing resource materials and activities which allow the students to practice the content being taught facilitates the transfer of learning. The students made the following recommendations to remove barriers to the transfer of learning: (1

To evaluate the use of polyester resin in preserving anatomical specimens for the study of human anatomy. We used 150 anatomical specimens, comprised of unfixed (fresh), fixed in 10% formalin and vascular casts of organs injected with vinyl acetate and polyester resin. The solution used consisted of polyester resin with the diluent styrene monomer and catalyst (peroxol). After embedding in this solution, models in transparent resin were obtained, allowing full observation of structures and conservation of the specimens used. upon evaluation of the specimens, we observed a high degree of transparency, which promoted a complete visualization of structures with perfect preservation of the anatomy. The average time for the completion of the embedding was 48 hours. Only 14 specimens (9.3%) were lost during the preparation. Polyester resin can be used for preserving anatomical specimens for teaching human anatomy in a practical, aesthetic and durable way.

Pre- and post-evaluations of implantable cardiac devices require innovative and critical testing in all phases of the design process. The Visible Heart ® Project was successfully launched in 1997 and 3 years later the Atlas of Human Cardiac Anatomy website was online. The Visible Heart ® methodologies and Atlas website can be used to better understand human cardiac anatomy, disease states and/or to improve cardiac device design throughout the development process. To date, Visible ® Heart methodologies have been used to reanimate 75 human hearts, all considered non-viable for transplantation. The Atlas is a unique free-access website featuring novel images of functional and fixed human cardiac anatomies from >400 human heart specimens. Furthermore, this website includes education tutorials on anatomy, physiology, congenital heart disease and various imaging modalities. For instance, the Device Tutorial provides examples of commonly deployed devices that were present at the time of in vitro reanimation or were subsequently delivered, including: leads, catheters, valves, annuloplasty rings, leadless pacemakers and stents. Another section of the website displays 3D models of vasculature, blood volumes, and/or tissue volumes reconstructed from computed tomography (CT) and magnetic resonance images (MRI) of various heart specimens. A new section allows the user to interact with various heart models. Visible Heart ® methodologies have enabled our laboratory to reanimate 75 human hearts and visualize functional cardiac anatomies and device/tissue interfaces. The website freely shares all images, video clips and CT/MRI DICOM files in honour of the generous gifts received from donors and their families.

2012-09-01

Digital modeling of human anatomy has become increasingly important and relies on well-documented quantitative anatomy literature. This type of documentation is common for the spine and pelvis; however, significant issues exist due to the lack of standardization in measurement and technique. Existing literature on quantitative anatomy for the spine and pelvis of white adults (aged 18-65 years, separated into decadal categories) was reviewed from the disciplines of anatomy, manipulative therapy, anthropometrics, occupational ergonomics, biomechanics and forensic science. The data were unified into a single normative model of the sub-axial spine. Two-dimensional orthographic drawings were produced from the 590 individual measurements identified, which informed the development of a 3D digital model. A similar review of full range of motion data was conducted as a meta-analysis and the results were applied to the existing model, providing an inter-connected, articulated digital spine. During these data analysis processes several inconsistencies were observed accompanied by an evidential lack of standardization with measurement and recording of data. These have been categorized as: anatomical terminology; scaling of measurements; measurement methodology, dimension and anatomical reference positions; global coordinate systems. There is inconsistency in anatomical terminology where independent researchers use the same terms to describe different aspects of anatomy or different terms for the same anatomy. Published standards exist for measurement methods of the human body regarding spatial interaction, anthropometric databases, automotive applications, clothing industries and for computer manikins, but none exists for skeletal anatomy. Presentation of measurements often lacks formal structure in clinical publications, seldom providing geometric reference points, therefore making digital reconstruction difficult.

The use of two-dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low-quality and high-quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low-quality or high-quality images, and then completed a comprehension test using either 2D images or three-dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high-quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high-quality vs. low-quality for hand anatomy P = 0.018; high-quality vs. low-quality for eye anatomy P = 0.247). Also, the benefit of high-quality images on hand anatomy learning was restricted to performance on short-answer (SA) questions immediately after learning (high-quality vs. low-quality on SA questions P = 0.018), but did not apply to performance on multiple-choice (MC) questions (high-quality vs. low-quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

Virtual Reality is becoming widespread in our society within very different areas, from industry to entertainment. It has many advantages in education as well, since it allows visualizing almost any object or going anywhere in a unique way. We will be focusing on medical education, and more specifically anatomy, where its use is especially interesting because it allows studying any structure of the human body by placing the user inside each one. By allowing virtual immersion in a body structure such as the interior of the cranium, stereoscopic vision goggles make these innovative teaching technologies a powerful tool for training in all areas of health sciences. The aim of this study is to illustrate the teaching potential of applying Virtual Reality in the field of human anatomy, where it can be used as a tool for education in medicine. A Virtual Reality Software was developed as an educational tool. This technological procedure is based entirely on software which will run in stereoscopic goggles to give users the sensation of being in a virtual environment, clearly showing the different bones and foramina which make up the cranium, and accompanied by audio explanations. Throughout the results the structure of the cranium is described in detailed from both inside and out. Importance of an exhaustive morphological knowledge of cranial fossae is further discussed. Application for the design of microsurgery is also commented.

Self-directed learning in gross human anatomy: assessment outcomes and student perceptions.

2008-01-01

Speech pathology students enrolled in a lecture-based gross human anatomy program completed two out of nine topics in self-directed mode. Student performance in quizzes was compared for the two modes, and the students completed questionnaires on their perceptions of the self-directed mode of delivery. Students performed as well in the first self-directed topic as they did in lecture-based material, but performance declined significantly on the second self-directed topic. Correlations showed that students who performed well in lecture-based topics also performed well on self-directed topics. The major issues that arose in the student questionnaires were primarily related to the amount of content in the topics and the length of time required for completion. We conclude that there is a strong need for appropriate design of distance education materials to reflect student perceptions of length, content, and time investment, and more importantly that there is a need to ensure extensive communication and support of students studying in distance education/self-directed modes for the first time.

Utilizing reality anatomy such as dissection and demonstrating using cadavers has been described as a superior way to create meaning. The chemicals used to embalm cadavers differentially alter the tissue of the human body, which has led to the usage of different processes along the hard to soft-fixed spectrum of preserved cadavers. A questionnaire based approach was used to gain a better insight into the opinion of anatomists on the use of preserved cadavers for the teaching of human anatomy. This study focused on anatomy teachers in the United Kingdom and Ireland. From the 125 participating anatomists, 34.4% were medically qualified, 30.4% had a PhD in a non-anatomical science and 22.4% had a PhD in an anatomical science, these figures include ten anatomists who had combinations of MD with the two other PhD qualifications. The main findings from the questionnaire were that 61.6% of participants agreed that hard-fixed formalin cadavers accurately resemble features of a human body whereas 21.6% disagreed. Moreover, anatomists rated the teaching aids on how accurately they resemble features of the human body as follows: plastic models the least accurate followed by plastinated specimens, hard fixed cadavers; soft preserved cadavers were considered to be the most accurate when it comes to resembling features of the human body. Though anatomists considered soft preserved cadavers as the most accurate tool, further research is required in order to investigate which techniques or methods provide better teaching tool for a range of anatomical teaching levels and for surgical training.

This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P < 0.0001). The percentage pass rate for the subject in the first call was higher in the BL group (87.9% versus 71.4%; P = 0.02), reflecting a lower incidence of students who failed to sit the examination (BL 4.3% versus TT 13.8%; P = 0.05). There were no differences regarding overall satisfaction with the teaching received. Blended learning was more effective than traditional teaching for teaching human anatomy.

Honoring our donors: a survey of memorial ceremonies in United States anatomy programs.

Many anatomy programs that incorporate dissection of donated human bodies hold memorial ceremonies of gratitude towards body donors. The content of these ceremonies may include learners' reflections on mortality, respect, altruism, and personal growth told through various humanities modalities. The task of planning is usually student- and faculty-led with participation from other health care students. Objective information on current memorial ceremonies for body donors in anatomy programs in the United States appears to be lacking. The number of programs in the United States that currently plan these memorial ceremonies and information on trends in programs undertaking such ceremonies remain unknown. Gross anatomy program directors throughout the United States were contacted and asked to respond to a voluntary questionnaire on memorial ceremonies held at their institution. The results (response rate 68.2%) indicated that a majority of human anatomy programs (95.5%) hold memorial ceremonies. These ceremonies are, for the most part, student-driven and nondenominational or secular in nature. Participants heavily rely upon speech, music, poetry, and written essays, with a small inclusion of other humanities modalities, such as dance or visual art, to explore a variety of themes during these ceremonies. © 2013 American Association of Anatomists.

Viewpoint: exploring the human interior: the roles of cadaver dissection and radiologic imaging in teaching anatomy.

Gunderman, Richard B; Wilson, Philip K

2005-08-01

For a variety of reasons, new radiological imaging techniques are supplanting traditional cadaver dissection in the teaching of human anatomy. The authors briefly review the historical forces behind this transition, and then explore the advantages and drawbacks of each approach. Cadaver dissection offers an active, hands-on exploration of human structure, provides deep insights into the meaning of human embodiment and mortality, and represents a profound rite of passage into the medical profession. Radiological imaging permits in vivo visualization, offers physiologic as well as anatomic insights, and represents the context in which contemporary practicing physicians most frequently encounter their patients' otherwise hidden internal anatomy. Despite its important strengths, radiology cannot simply substitute for cadaver dissection, and the best models for teaching gross anatomy will incorporate both cadaver dissection and radiological imaging.

An untold story: The important contributions of Muslim scholars for the understanding of human anatomy.

PubMed

Alghamdi, Malak A; Ziermann, Janine M; Diogo, Rui

2017-06-01

It is usually assumed that Galen is one of the fathers of anatomy and that between the Corpus Galenicum and the Renaissance there was no major advance in anatomical knowledge. However, it is also consensually accepted that Muslim scholars had the intellectual leadership from the 8th/9th to 13th centuries, and that they made remarkable progresses in numerous scientific fields including medicine. So, how is it possible that they did not contribute to advance human anatomy during that period? According to the dominant view, Muslim scholars exclusively had a passive role: their transmission of knowledge from the Greeks to the West. Here, we summarize, for the first time in a single paper, the studies of major Muslim scholars that published on human anatomy before Vesalius. This summary is based on analyses of original Arabic texts and of more recent publications by anatomists and historians, and on comparisons between the descriptions provided by Galen and by these Muslim scholars. We show that Arabic speakers and Persians made important advances in human anatomy well before Vesalius. The most notable exception concerns the muscular system: strikingly, there were apparently neither advances made by Muslims nor by Westerners for more than 1000 years. Unbiased discussions of these and other related issues, and particularly of the mainly untold story about the major contributions of Muslim scholars to anatomy, are crucial to our knowledge of the history of anatomy, biology and sciences, and also of our way of thinking, biases, and prejudices.

2012-07-01

To quantifiably measure the impact of self-instructed radiological anatomy modules on anatomy comprehension, demonstrated by radiology, gross, and written exams. Study guides for independent use that emphasized structural relationships were created for use with two online radiology atlases. A guide was created for each module of the first year medical anatomy course and incorporated as an optional course component. A total of 93 of 96 eligible students participated. All exams were normalized to control for variances in exam difficulty and body region tested. An independent t-test was used to compare overall exam scores with respect to guide completion or incompletion. To account for aptitude differences between students, a paired t-test of each student's exam scores with and without completion of the associated guide was performed, thus allowing students to serve as their own controls. Twenty-one students completed no study guides; 22 completed all six guides; and 50 students completed between one and five guides. Aggregate comparisons of all students' exam scores showed significantly improved mean performance when guides were used (radiology, 57.8% [percentile] vs. 45.1%, P < .001; gross, 56.9% vs. 46.5%, P = .001; written, 57.8% vs. 50.2%, P = .011). Paired comparisons among students who completed between one and five guides demonstrated significantly higher mean practical exam scores when guides were used (radiology, 49.3% [percentile] vs. 36.0%, P = .001; gross, 51.5% vs. 40.4%, P = .005), but not higher written scores. Radiological anatomy study guides significantly improved anatomy comprehension on radiology, gross, and written exams. Copyright © 2012 AUR. Published by Elsevier Inc. All rights reserved.

Technological advances in the field of biological imaging now allow multi-modal studies of human embryo anatomy. The aim of this study was to assess the high magnetic field μMRI feasibility in the study of small human embryos (less than 21mm crown-rump) as a new tool for the study of human descriptive embryology and to determine better sequence characteristics to obtain higher spatial resolution and higher signal/noise ratio. Morphological study of four human embryos belonging to the historical collection of the Department of Anatomy in the Faculty of Medicine of Reims was undertaken by μMRI. These embryos had, successively, crown-rump lengths of 3mm (Carnegie Stage, CS 10), 12mm (CS 16), 17mm (CS 18) and 21mm (CS 20). Acquisition of images was performed using a vertical nuclear magnetic resonance spectrometer, a Bruker Avance III, 500MHz, 11.7T equipped for imaging. All images were acquired using 2D (transverse, sagittal and coronal) and 3D sequences, either T1-weighted or T2-weighted. Spatial resolution between 24 and 70μm/pixel allowed clear visualization of all anatomical structures of the embryos. The study of human embryos μMRI has already been reported in the literature and a few atlases exist for educational purposes. However, to our knowledge, descriptive or morphological studies of human developmental anatomy based on data collected these few μMRI studies of human embryos are rare. This morphological noninvasive imaging method coupled with other techniques already reported seems to offer new perspectives to descriptive studies of human embryology.

In this study, MR B(+)(1) imaging is employed to experimentally verify the validity of FDTD simulations of electromagnetic field patterns in human anatomies. Measurements and FDTD simulations of the B(+)(1) field induced by a 3 T MR body coil in a human corpse were performed. It was found that MR B(+)(1) imaging is a sensitive method to measure the radiofrequency (RF) magnetic field inside a human anatomy with a precision of approximately 3.5%. A good correlation was found between the B(+)(1) measurements and FDTD simulations. The measured B(+)(1) pattern for a human pelvis consisted of a global, diagonal modulation pattern plus local B(+)(1) heterogeneties. It is believed that these local B(+)(1) field variations are the result of peaks in the induced electric currents, which could not be resolved by the FDTD simulations on a 5 mm(3) simulation grid. The findings from this study demonstrate that B(+)(1) imaging is a valuable experimental technique to gain more knowledge about the dielectric interaction of RF fields with the human anatomy.

Reasonable classical concepts in human lower limb anatomy from the viewpoint of the primitive persistent sciatic artery and twisting human lower limb.

PubMed

Kawashima, Tomokazu; Sasaki, Hiroshi

2010-11-01

The main aim of this review is (1) to introduce the two previous studies we published human lower limb anatomy based on the conventional macroscopic anatomical [corrected] criteria with hazardous recognition of this description, (2) to activate the discussion whether the limb homology exists, and (3) to contribute to future study filling the gap between the gross anatomy and embryology. One of the topics we discussed was the human persistent sciatic artery. To date, numerous human cases of persistent sciatic artery have been reported in which the anomalous artery was present in the posterior compartment of the thigh alongside the sciatic nerve. As one of the important criteria for assessing the human primitive sciatic artery, its ventral arterial position with respect to the sciatic nerve is reasonable based on the initial positional relationship between ventral arterial and dorsal nervous systems and comparative anatomical findings. We also discuss ways of considering the topography of muscles of the lower limb and their innervations compared to those of the upper limb. We propose a schema of the complex anatomical characteristics of the lower limb based on the vertebrate body plan. According to this reasonable schema, the twisted anatomy of the lower limb can be understood more easily. These two main ideas discussed in this paper will be useful for further understanding of the anatomy of the lower limb and as a first step for future. We hope that the future study in lower limb will be further developed by both viewpoints of the classical gross anatomy and recent embryology.

The anatomy of anatomy: a review for its modernization.

Sugand, Kapil; Abrahams, Peter; Khurana, Ashish

Anatomy has historically been a cornerstone in medical education regardless of nation or specialty. Until recently, dissection and didactic lectures were its sole pedagogy. Teaching methodology has been revolutionized with more reliance on models, imaging, simulation, and the Internet to further consolidate and enhance the learning experience. Moreover, modern medical curricula are giving less importance to anatomy education and to the acknowledged value of dissection. Universities have even abandoned dissection completely in favor of user-friendly multimedia, alternative teaching approaches, and newly defined priorities in clinical practice. Anatomy curriculum is undergoing international reformation but the current framework lacks uniformity among institutions. Optimal learning content can be categorized into the following modalities: (1) dissection/prosection, (2) interactive multimedia, (3) procedural anatomy, (4) surface and clinical anatomy, and (5) imaging. The importance of multimodal teaching, with examples suggested in this article, has been widely recognized and assessed. Nevertheless, there are still ongoing limitations in anatomy teaching. Substantial problems consist of diminished allotted dissection time and the number of qualified anatomy instructors, which will eventually deteriorate the quality of education. Alternative resources and strategies are discussed in an attempt to tackle these genuine concerns. The challenges are to reinstate more effective teaching and learning tools while maintaining the beneficial values of orthodox dissection. The UK has a reputable medical education but its quality could be improved by observing international frameworks. The heavy penalty of not concentrating on sufficient anatomy education will inevitably lead to incompetent anatomists and healthcare professionals, leaving patients to face dire repercussions.

This paper describes how the Atlas of Human Cardiac Anatomy website can be used to improve cardiac device design throughout the process of development. The Atlas is a free-access website featuring novel images of both functional and fixed human cardiac anatomy from over 250 human heart specimens. This website provides numerous educational tutorials on anatomy, physiology and various imaging modalities. For instance, the 'device tutorial' provides examples of devices that were either present at the time of in vitro reanimation or were subsequently delivered, including leads, catheters, valves, annuloplasty rings and stents. Another section of the website displays 3D models of the vasculature, blood volumes and/or tissue volumes reconstructed from computed tomography and magnetic resonance images of various heart specimens. The website shares library images, video clips and computed tomography and MRI DICOM files in honor of the generous gifts received from donors and their families.

Human dissection commonly occurs early in the undergraduate medical school curriculum, thus presenting an immediate opportunity for educators to teach and encourage humanistic qualities of respect, empathy, and compassion. The purpose of this study was to measure the impact of the Donor Luncheon, a unique program in which medical students meet the families of the anatomical donor prior to dissection in the anatomy course at the University of Oklahoma College of Medicine. Students were randomized into groups of 8 to attend the luncheon and either met with family of the donor or attended the luncheon with no donor family present. A questionnaire measured students' attitudes at 2 weeks, 6 weeks, and at the conclusion of the anatomy course. Factor analysis revealed 5 scales. Analysis revealed statistically significant differences across time for Donor as Person, Dissection Process, and Donor as Patient and statistically significant differences between groups for Donor as Person and Donor as Patient. These results suggest that this program can provide students with the opportunity to maintain more humanistic attitudes at the beginning of their medical education career.

Information systems are increasing in importance in biomedical sciences and medical practice. The nomenclature rules of human anatomy were reviewed for adequacy with respect to modern needs. New rules are proposed here to ensure that each Latin term is uniquely associated with an anatomical entity, as short and simple as possible, and machine-interpretable. Observance of these recommendations will also benefit students and translators of the Latin terms into other languages. Clin.

Out of the dissecting room: news media portrayal of human anatomy teaching and research.

PubMed

Regan de Bere, Sam; Petersen, Alan

2006-07-01

Radical changes in medical research and education have recently led to a number of innovative developments in terms of how human anatomy is represented and understood. New ways of introducing medical students to anatomy (including living anatomies and virtual simulations) have provoked widespread debate, with discussion of their relative merits compared to more traditional approaches that use cadaveric dissection. Outside the field of medicine, in the wider public sphere, the practice of anatomical study may often seem mysterious. The dissemination of news on anatomy, we contend, is central to the question of how medical researchers and educators engage with the public. Our analysis of news media coverage in the UK demonstrates that news-making, by giving prominence to certain facts, themes and images, serves to mask issues about anatomy and its practices that need debate. We examine the ways in which news media, through processes of selection and the 'framing' of issues, may perform an agenda-setting role. We draw attention to the use of positive 'awe and amazement' frames including 'miracles of modern science', 'medical heroes', and 'gifts of life', alongside more negative 'guts and gore' coverage including 'Frankenstein', 'Brave New World' and 'Rape of the Body' frames that concentrate on high profile scandals associated with the use and misuse of human bodies, tissues and parts. We also highlight the selective use of commentaries from members of the medical profession, which are more prevalent in positive 'awe and amazement' stories than in stories with negative coverage. We conclude by arguing for greater collaboration between journalists on the one hand, and medical educators and researchers on the other, in the making of news in order to provide portrayals of anatomy which bear a closer relationship to the everyday reality of professional work.

Simulation of radiofrequency ablation in real human anatomy.

PubMed

Zorbas, George; Samaras, Theodoros

2014-12-01

The objective of the current work was to simulate radiofrequency ablation treatment in computational models with realistic human anatomy, in order to investigate the effect of realistic geometry in the treatment outcome. The body sites considered in the study were liver, lung and kidney. One numerical model for each body site was obtained from Duke, member of the IT'IS Virtual Family. A spherical tumour was embedded in each model and a single electrode was inserted into the tumour. The same excitation voltage was used in all cases to underline the differences in the resulting temperature rise, due to different anatomy at each body site investigated. The same numerical calculations were performed for a two-compartment model of the tissue geometry, as well as with the use of an analytical approximation for a single tissue compartment. Radiofrequency ablation (RFA) therapy appears efficient for tumours in liver and lung, but less efficient in kidney. Moreover, the time evolution of temperature for a realistic geometry differs from that for a two-compartment model, but even more for an infinite homogenous tissue model. However, it appears that the most critical parameters of computational models for RFA treatment planning are tissue properties rather than tissue geometry. Computational simulations of realistic anatomy models show that the conventional technique of a single electrode inside the tumour volume requires a careful choice of both the excitation voltage and treatment time in order to achieve effective treatment, since the ablation zone differs considerably for various body sites.

Human patient simulators and airway training manikins are widely used to train airway management skills to medical professionals. Furthermore, these patient simulators are employed as standardized "patients" to evaluate airway devices. However, little is known about how realistic these patient simulators and airway-training manikins really are. This trial aimed to evaluate the upper airway anatomy of four high-fidelity patient simulators and two airway trainers in comparison with actual patients by means of radiographic measurements. The volume of the pharyngeal airspace was the primary outcome parameter. Computed tomography scans of 20 adult trauma patients without head or neck injuries were compared with computed tomography scans of four high-fidelity patient simulators and two airway trainers. By using 14 predefined distances, two cross-sectional areas and three volume parameters of the upper airway, the manikins' similarity to a human patient was assessed. The pharyngeal airspace of all manikins differed significantly from the patients' pharyngeal airspace. The HPS Human Patient Simulator (METI®, Sarasota, FL) was the most realistic high-fidelity patient simulator (6/19 [32%] of all parameters were within the 95% CI of human airway measurements). The airway anatomy of four high-fidelity patient simulators and two airway trainers does not reflect the upper airway anatomy of actual patients. This finding may impact airway training and confound comparative airway device studies.

The Anatomy of the Glenoid Labrum: A Comparison between Human and Dog

The anatomy of the glenohumeral joint in humans is characterized by static and dynamic stabilizing structures. In particular the glenoid labrum (GL), the proximal attachment of the joint capsule and the lateral glenohumeral ligament, is an important passive stabilizer in the human shoulder. Although canine animal models are used frequently to investigate the complex biomechanics of the shoulder, few data regarding the microstructure of the canine GL are available. In this study, the anatomy of the canine GL and related structures (n = 20) was investigated and compared with the human anatomic situation (n = 36). In both human and beagle joints, the GL consisted of 3 zones—the transition zone, shifting zone, and meniscoid fold, but not all 3 zones were present in all joint segments from canine joints. In particular the peripheral parts of the GL showed rich vascularization in both species. The height and width of the GL in the histologic specimens indicated that the GL is of less importance as a passive stabilizer in dogs. Additional differences between the human and canine CL include the joint ligaments, tendons of the shoulder joint, and lack of rotator cuff. The structural and biomechanical characteristics of the joints of quadrupedal animals raise the question of their appropriateness for shoulder research. PMID:19887031

The primary purpose of this study was to determine the effectiveness of implementing desktop 3-dimensional (3D) stereo images of human anatomy into an undergraduate human anatomy distance laboratory. User perceptions of 2D and 3D images were gathered via questionnaire in order to determine ease of use and level of satisfaction associated with the 3D software in the online learning environment. Mayer's (2001, p. 184) principles of design were used to develop the study materials that consisted of PowerPoint presentations and AVI files accessed via Blackboard. The research design employed a mixed-methods approach. Volunteers each were administered a demographic survey and were then stratified into groups based upon pre-test scores. A total sample size of 62 pairs was available for combined data analysis. Quantitative research questions regarding the effectiveness of 2D versus the 3D treatment were analyzed using a doubly-multivariate repeated measures (Doubly-MANOVA) design. Paired test scores achieved by undergraduates on a laboratory practical of identification and spatial relationships of the bones and features of a human skull were used in the analysis. The questionnaire designed to gather user perceptions consisted of quantitative and qualitative questions. Response frequencies were analyzed for the two groups and common themes were noted. Results revealed a statistically significant difference in group means for the main effect of the treatment groups 2D and 3D and for the variables of identification and relationship with the 3D group outperforming the 2D group on both dependent variables. Effect sizes were determined to be small, 0.215 for the identification variable and 0.359 for the relationship variable. Overall, all students liked the convenience of using PowerPoint and AVI files online. The 3D group felt their PowerPoint was more realistic than did the 2D group and both groups appreciated the detailed labeling of the online images. One third of the

DeHoff, Mary Ellen; Clark, Krista L; Meganathan, Karthikeyan

2011-03-01

Alternatives and/or supplements to animal dissection are being explored by educators of human anatomy at different academic levels. Clay modeling is one such alternative that provides a kinesthetic, three-dimensional, constructive, and sensory approach to learning human anatomy. The present study compared two laboratory techniques, clay modeling of human anatomy and dissection of preserved cat specimens, in the instruction of muscles, peripheral nerves, and blood vessels. Specifically, we examined the effect of each technique on student performance on low-order and high-order questions related to each body system as well as the student-perceived value of each technique. Students who modeled anatomic structures in clay scored significantly higher on low-order questions related to peripheral nerves; scores were comparable between groups for high-order questions on peripheral nerves and for questions on muscles and blood vessels. Likert-scale surveys were used to measure student responses to statements about each laboratory technique. A significantly greater percentage of students in the clay modeling group "agreed" or "strongly agreed" with positive statements about their respective technique. These results indicate that clay modeling and cat dissection are equally effective in achieving student learning outcomes for certain systems in undergraduate human anatomy. Furthermore, clay modeling appears to be the preferred technique based on students' subjective perceptions of value to their learning experience.

Systemic Human Anatomy is a full credit, upper year undergraduate course with a (prosection) laboratory component at Western University Canada. To meet enrollment demands beyond the physical space of the laboratory facility, a fully online section was developed to run concurrently with the traditional face to face (F2F) course. Lectures given to F2F students are simultaneously broadcasted to online students using collaborative software (Blackboard Collaborate). The same collaborative software is used by a teaching assistant to deliver laboratory demonstrations in which three-dimensional (3D) virtual anatomical models are manipulated. Ten commercial software programs were reviewed to determine their suitability for demonstrating the virtual models, resulting in the selection of Netter's 3D Interactive Anatomy. Supplementary online materials for the central nervous system were developed by creating 360° images of plastinated prosected brain specimens and a website through which they could be accessed. This is the first description of a fully online undergraduate anatomy course with a live, interactive laboratory component. Preliminary data comparing the online and F2F student grades suggest that previous student academic performance, and not course delivery format, predicts performance in anatomy. Future qualitative studies will reveal student perceptions about their learning experiences in both of the course delivery formats. © 2014 American Association of Anatomists.

Connecting art and science: An interdisciplinary strategy and its impact on the affective domain of community college human anatomy students

NASA Astrophysics Data System (ADS)

Petti, Kevin

Educational objectives are often described within the framework of a three-domain taxonomy: cognitive, affective and psychomotor. While most of the research on educational objectives has focused on the cognitive domain, the research that has been conducted on the affective domain, which speaks to emotions, attitudes, and values, has identified a number of positive outcomes. One approach to enhancing the affective domain is that of interdisciplinary education. Science education research in the realm of interdisciplinary education and affective outcomes is limited; especially research conducted on community college students of human anatomy. This project investigated the relationship between an interdisciplinary teaching strategy and the affective domain in science education by utilizing an interdisciplinary lecture in a human anatomy class. Subjects were anatomy students in a California community college who listened to a one-hour lecture describing the cultural, historical and scientific significance of selected pieces of art depicting human dissection in European medieval and Renaissance universities. The focus was on how these renderings represent the state of anatomy education during their respective eras. After listening to the lecture, subjects were administered a 35-question survey that was composed of 14 demographic questions and 21 Likert-style statements that asked respondents to rate the extent to which the intervention influenced their affective domain. Descriptive statistics were then used to determine which component of the affective domain was most influenced, and multiple regression analysis was used to examine the extent to which individual differences along the affective continuum were explained by select demographic measures such as gender, race/ethnicity, education level, and previous exposure to science courses. Results indicate that the interdisciplinary intervention had a positive impact on every component of the affective domain hierarchy

After a considerable amount of research and experimentation, cat dissection was replaced with rat dissection and clay modeling in the human anatomy and physiology laboratory curricula at La Guardia Community College (LAGCC), a large urban community college of the City University of New York (CUNY). This article describes the challenges faculty overcame and the techniques used to solve them. Methods involved were: developing a laboratory manual in conjunction with the publisher, holding training sessions for faculty and staff, the development of instructional outlines for students and lesson plans for faculty, the installation of storage facilities to hold mannequins instead of cat specimens, and designing mannequin clean-up techniques that could be used by more than one thousand students each semester. The effectiveness of these curricular changes was assessed by examining student muscle practical examination grades and the responses of faculty and students to questionnaires. The results demonstrated that the majority of faculty felt prepared to teach using clay modeling and believed the activity was effective in presenting lesson content. Students undertaking clay modeling had significantly higher muscle practical examination grades than students undertaking cat dissection, and the majority of students believed that clay modeling was an effective technique to learn human skeletal, respiratory, and cardiovascular anatomy, which included the names and locations of blood vessels. Furthermore, the majority of students felt that rat dissection helped them learn nervous, digestive, urinary, and reproductive system anatomy. Faculty experience at LAGCC may serve as a resource to other academic institutions developing new curricula for large, on-going courses. © 2013 American Association of Anatomists.

Singh, Rajani; Shane Tubbs, R; Gupta, Kavita; Singh, Man; Jones, D Gareth; Kumar, Raj

2015-12-01

The continuous decrease in teaching time, the artificially created scarcity of competent anatomical faculties and a reduced allocation of resources have brought about the decline of anatomy in medical education. As a result of this, anatomical knowledge and the standard of medical education have fallen with consequences including safety in clinical practice. The aim of the present study is to analyze this declining phase of anatomy and its impact on medical education and to consider corrective measures. This article expresses comparative viewpoints based on a review of the literature. Anatomy enables doctors to master the language of medical science so they can communicate with patients, the public and fellow doctors and diagnose and treat diseases successfully in all medical fields. No medical specialist or expert can master their field without adequate knowledge of human anatomy. The shrinkage of anatomical schedules, inadequate faculties and declining allocation of resources is therefore unfortunate. These factors produce stress in both student and faculty creating gaps in anatomical knowledge that means insufficient skill is developed to practice medicine safely. This decline is hazardous not only to the medical profession but also to society. Reforms consisting of balanced rescheduling of medical curricula and optimum resource allocation have been proposed to improve the standard of education of doctors.

Practical session assessments in human anatomy: Weightings and performance.

2016-07-08

Assessment weighting within a given module can be a motivating factor for students when deciding on their commitment level and time given to study a specific topic. In this study, an analysis of assessment performances of second year anatomy students was performed over four years to determine if (1) students performed better when a higher weighting was given to a set of practical session assessments and (2) whether an improved performance in the practical session assessments had a carry-over effect on other assessment tasks within that anatomy module and/or other anatomy modules that follow. Results showed that increasing the weighting of practical session assessments improved the average mark in that assessment and also improved the percentage of students passing that assessment. Further, it significantly improved performance in the written end-semester examination within the same module and had a carry-over effect on the anatomy module taught in the next teaching period, as students performed better in subsequent practical session assessments as well as subsequent end-semester examinations. It was concluded that the weighting of assessments had significant influences on a student's performance in that, and subsequent, assessments. It is postulated that practical session assessments, designed to develop deep learning skills in anatomy, improved efficacy in student performance in assessments undertaken in that and subsequent anatomy modules when the weighting of these assessments was greater. These deep learning skills were also transferable to other methods of assessing anatomy.

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11-factor, 132-items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale-level content validity index [total] = 0.646); good response process evidence (scale-level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604-0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X 2  = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

In this study we provide detailed quantification of upper extremity nerve and fascicular anatomy. The purpose is to provide values and trends in neural features useful for clinical applications and neural interface device design. Nerve cross-sections were taken from 4 ulnar, 4 median, and 3 radial nerves from 5 arms of 3 human cadavers. Quantified nerve features included cross-sectional area, minor diameter, and major diameter. Fascicular features analyzed included count, perimeter, area, and position. Mean fascicular diameters were 0.57 ± 0.39, 0.6 ± 0.3, 0.5 ± 0.26 mm in the upper arm and 0.38 ± 0.18, 0.47 ± 0.18, 0.4 ± 0.27 mm in the forearm of ulnar, median, and radial nerves, respectively. Mean fascicular diameters were inversely proportional to fascicle count. Detailed quantitative anatomy of upper extremity nerves is a resource for design of neural electrodes, guidance in extraneural procedures, and improved neurosurgical planning.

Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

Greek anatomist herophilus: the father of anatomy

PubMed Central

Bay, Noel Si-Yang

2010-01-01

One of the most stirring controversies in the history of Anatomy is that Herophilus, an ancient Greek anatomist and his younger contemporary, Erasistratus, were accused of performing vivisections of living humans. However, this does not detract from the fact that Herophilus has made phenomenal anatomical observations of the human body which have contributed significantly towards the understanding of the brain, eye, liver, reproductive organs and nervous system. It is notable that he was the first person to perform systematic dissection of the human body and is widely acknowledged as the Father of Anatomy. He has been hailed as one of the greatest anatomists that ever lived, rivaled only by Andreas Vesalius who is regarded as the founder of modern human anatomy. PMID:21267401

Diffeomorphometry and geodesic positioning systems for human anatomy.

PubMed

Miller, Michael I; Younes, Laurent; Trouvé, Alain

2014-03-01

The Computational Anatomy project has largely been a study of large deformations within a Riemannian framework as an efficient point of view for generating metrics between anatomical configurations. This approach turns D'Arcy Thompson's comparative morphology of human biological shape and form into a metrizable space. Since the metric is constructed based on the geodesic length of the flows of diffeomorphisms connecting the forms, we call it diffeomorphometry . Just as importantly, since the flows describe algebraic group action on anatomical submanifolds and associated functional measurements, they become the basis for positioning information, which we term geodesic positioning . As well the geodesic connections provide Riemannian coordinates for locating forms in the anatomical orbit, which we call geodesic coordinates . These three components taken together - the metric, geodesic positioning of information, and geodesic coordinates - we term the geodesic positioning system . We illustrate via several examples in human and biological coordinate systems and machine learning of the statistical representation of shape and form.

An Allometric Analysis of Sex and Sex Chromosome Dosage Effects on Subcortical Anatomy in Humans

2016-01-01

Structural neuroimaging of humans with typical and atypical sex-chromosome complements has established the marked influence of both Yand X-/Y-chromosome dosage on total brain volume (TBV) and identified potential cortical substrates for the psychiatric phenotypes associated with sex-chromosome aneuploidy (SCA). Here, in a cohort of 354 humans with varying karyotypes (XX, XY, XXX, XXY, XYY, XXYY, XXXXY), we investigate sex and SCA effects on subcortical size and shape; focusing on the striatum, pallidum and thalamus. We find large effect-size differences in the volume and shape of all three structures as a function of sex and SCA. We correct for TBV effects with a novel allometric method harnessing normative scaling rules for subcortical size and shape in humans, which we derive here for the first time. We show that all three subcortical volumes scale sublinearly with TBV among healthy humans, mirroring known relationships between subcortical volume and TBV among species. Traditional TBV correction methods assume linear scaling and can therefore invert or exaggerate sex and SCA effects on subcortical anatomy. Allometric analysis restricts sex-differences to: (1) greater pallidal volume (PV) in males, and (2) relative caudate head expansion and ventral striatum contraction in females. Allometric analysis of SCA reveals that supernumerary X- and Y-chromosomes both cause disproportionate reductions in PV, and coordinated deformations of striatopallidal shape. Our study provides a novel understanding of sex and sex-chromosome dosage effects on subcortical organization, using an allometric approach that can be generalized to other basic and clinical structural neuroimaging settings. SIGNIFICANCE STATEMENT Sex and sex-chromosome dosage (SCD) are known to modulate human brain size and cortical anatomy, but very little is known regarding their impact on subcortical structures that work with the cortex to subserve a range of behaviors in health and disease.

"No interest in human anatomy as such": Frederic Wood Jones dissects anatomical investigation in the United States in the 1920s.

PubMed

Jones, Ross L

2014-03-01

In 1926, Frederic Wood Jones, professor of Anatomy at the University of Adelaide and a leading figure in the British anatomical world, took a Rockefeller Foundation funded trip to the United States in order to inspect anatomy programmes and medical museums and to meet leading figures in the anatomical and anthropological world. His later reflections paint a picture of a discipline in transition. Physical anthropology and gross anatomy were coming to a crisis point in the United States, increasingly displaced by research in histology, embryology and radiological anatomy. Meanwhile, in Britain and its colonial outposts, anatomists such as Wood Jones were attempting to re-invigorate the discipline in the field, studying biological specimens as functional and active agents in their particular milieus, but with human dissection at the core. Thus, an examination of this trip allows us to see how the interaction between two traditions in anatomy informed the process of the development of human biology in this critical period.

2003-10-01

The purpose of this study was to explore the course conditions that support the development of meaningful student learning in an introductory undergraduate human anatomy and physiology course. The study was conducted during an 8-week summer-session at a small mid-western university. Classroom observations and taped recordings of class sessions were used to determine content episodes within the instructional unit, opportunities for learning created by the instructor, demonstrations of information processing by the students, and the ways in which the instructor used the Personal Response System (PRS). Student interviews were used to determine students' level of understanding of pre-test and post-test items. Student interviews and a questionnaire were used to determine students' perceptions of the PRS as a learning tool. Findings reveal that the instructor had different expectations of students when posing verbal questions in-class than he had when posing PRS questions. The use of verbal questions did not permit demonstrations of student understanding; however, the use of the PRS did result in demonstrations of student understanding. Questions posed via the use of the PRS were categorized according to cognitive level. The cognitive level of the questions increased with time over the instructional unit and within the content episodes. Students demonstrated deeper understanding of the topics after instruction than they did before instruction. Students reported more in-class thinking about the content, more discussion of the content with their neighbors, more regular class attendance, more opportunities for deeper learning, and a general preference for the PRS over traditional lectures. Findings of the study indicate that the instructional decisions about the use of questions influences the opportunities for students to process information and demonstrate their understanding of the content and that students valued these opportunities. A better understanding of the

Historically, cadavers have been used for the study of anatomy. Nowadays, the territorial and legal limitations of this approach have led to the introduction of alternative teaching methods such as the use of practical exercise consisting of dissection and observation of animal organs. The aim of this study was to evaluate the use of practical training on animal organs compared with the traditional method of anatomy teaching, based on the dissection of human cadavers. In this study, we seek to demonstrate the usefulness of practical exercise on animal organs. This practical training was held a week after the series of lectures, thus leaving time for the students to learn and understand the topics discussed. Immediately after the lecture, all of the students completed a preliminary test to assess the immediate effect of the lecture. Immediately before the practical exercise, both control and experimental groups completed a second test to assess the effectiveness of personal study. Immediately after practical training, a third test was completed by the experimental group and the control group (no practical activity on animal organs) to highlight the added value of hands-on practice in addition to the lecture. Data obtained from statistical analysis showed a p<0.05 (control group vs. experimental group) only for the third test as expected, highlighting significant differences in anatomy learning between control and experimental groups. Thus, the results of this study emphasize the utility of practical training on animal organs in learning and understanding anatomy, considering the limitations of the use of cadavers.

Anatomy, Development, and Function of the Human Pelvis.

PubMed

DeSilva, Jeremy M; Rosenberg, Karen R

2017-04-01

The pelvis is an anatomically complex and functionally informative bone that contributes directly to both human locomotion and obstetrics. Because of the pelvis' important role in obstetrics, it is one of the most sexually dimorphic bony elements of the human body. The complex intersection of pelvic dimorphism, locomotion, and obstetrics has been reenergized by exciting new research, and many papers in this special issue of the pelvis help provide clarity on the relationship between pelvic form (especially female) and locomotor function. Compared to the pelvis of our ape relatives, the human pelvis is uniquely shaped; it is superoinferiorly short and stout, and mediolaterally wide-critical adaptations for bipedalism that are already present in some form very early in the history of the hominin lineage. In this issue, 13 original research papers address the anatomy, development, variation, and function of the modern human pelvis, with implications for understanding the selection pressures that shaped and continue to shape this bone. This rich collection of scholarship moves our understanding of the pelvis forward, while raising dozens of new questions that we hope will serve as inspiration for colleagues and students (both current and future) puzzled by this fascinatingly complex bone.

2014-01-01

Video and photography are often used for delivering content within the anatomical sciences. However, instructors typically produce these resources to provide instructional or procedural information. Although the benefits of learner-generated content have been explored within educational research, virtually no studies have investigated the use of learner-generated video and photograph content within anatomy dissection laboratories. This study outlines an activity involving learner-generated video diaries and learner-generated photograph assignments produced during anatomy laboratory sessions. The learner-generated photographs and videos provided instructors with a means of formative assessment and allowed instructors to identify evidence of collaborative behavior in the laboratory. Student questionnaires (n = 21) and interviews (n = 5), as well as in-class observations, were conducted to examine student perspectives on the laboratory activities. The quantitative and qualitative data were examined using the framework of activity theory to identify contradictions between student expectations of, and engagement with, the activity and the actual experiences of the students. Results indicate that learner-generated photograph and video content can act as a rich source of data on student learning processes and can be used for formative assessment, for observing collaborative behavior, and as a starting point for class discussions. This study stresses the idea that technology choice for activities must align with instructional goals. This research also highlights the utility of activity theory as a framework for assessing classroom and laboratory activities, demonstrating that this approach can guide the development of laboratory activities. © 2014 American Association of Anatomists.

The hypothenar eminence is the thick soft tissue mass located on the ulnar side of the palm. Understanding its location and contents is important for understanding certain aspects of hand function. Variation in motor nerve distribution of the hypothenar muscles makes surgery of the ulnar side of the palm more challenging. To avoid injury to nerve branches, knowledge of these differences is imperative. This article discusses the muscular anatomy and function, vascular anatomy, and nerve anatomy and innervation of the hypothenar muscles. Copyright © 2012 Elsevier Inc. All rights reserved.

Michelangelo's major interest was the Life of the Soul as expressed in the beautiful structure and movement of the human body, which he often called the "mortal veil" of the divine intentions. This study ascertains Michelangelo's interest in and acquisition of the knowledge of human anatomy, the use of small anatomical models to crystallize his concepts into reality and the application of anatomy to his art. Relatively little is known of this interaction between anatomy and art in Michelangelo's life and work.

Tracheobronchial cast production and use in an undergraduate human anatomy course.

PubMed

Cope, Lee Anne

2008-01-01

Silastic E RTV silicone was used to produce tracheobronchial cast for use in an undergraduate human anatomy course. Following air-drying, the trachea and lungs were injected with E RTV silicone and allowed to cure for 24 hr. The parenchyma was then removed from the tracheobronchial cast by maceration and boiling and then whitened in a 10% solution of hydrogen peroxide. The result was an anatomical replica that illustrates the branching pattern of the tracheobronchial tree and looks very similar to human even though canine lungs were used. In addition, this cast is very flexible and durable enough to stand up to repeated student handling.

This paper presents an empirical study of a formative neural network-based assessment approach by using mobile technology to provide pharmacy students with intelligent diagnostic feedback. An unsupervised learning algorithm was integrated with an audience response system called SIDRA in order to generate states that collect some commonality in responses to questions and add diagnostic feedback for guided learning. A total of 89 pharmacy students enrolled on a Human Anatomy course were taught using two different teaching methods. Forty-four students employed intelligent SIDRA (i-SIDRA), whereas 45 students received the same training but without using i-SIDRA. A statistically significant difference was found between the experimental group (i-SIDRA) and the control group (traditional learning methodology), with T (87) = 6.598, p < 0.001. In four MCQs tests, the difference between the number of correct answers in the first attempt and in the last attempt was also studied. A global effect size of 0.644 was achieved in the meta-analysis carried out. The students expressed satisfaction with the content provided by i-SIDRA and the methodology used during the process of learning anatomy (M = 4.59). The new empirical contribution presented in this paper allows instructors to perform post hoc analyses of each particular student's progress to ensure appropriate training.

Complementing anatomy education using three-dimensional anatomy mobile software applications on tablet computers.

2014-04-01

Anatomy has traditionally been a cornerstone of medical education, which has been taught via dissection and didactic lectures. The rising prevalence of mobile tablet technology means medical software applications ("apps") play an increasingly important role in medical education. The applications highlighted in this article will aid anatomical educators to identify which are the most useful in clinical, academic, and educational environments. These have been systematically identified by downloading all applications with keywords related to anatomy and then carrying out qualitative assessment. Novel anatomy applications from developers such as Visible Body, 3D4Medical, and Pocket Anatomy allow students to visualize and manipulate complex anatomical structures using detailed 3D models. They often contain additional content including clinical correlations and a range of media from instructional videos to interactive quiz functions. The strength of tablet technology lies in its ability to consolidate and present anatomical information to the user in the most appropriate manner for their learning style. The only question mark remains over the level of detail and accuracy of these applications. Innovative medical educators who embrace tablet technology will find that anatomy applications serve as a useful learning tool when used in conjunction with existing teaching setups.

Anatomy teaching methods have evolved as the medical undergraduate curriculum has modernized. Traditional teaching methods of dissection, prosection, tutorials and lectures are now supplemented by anatomical models and e-learning. Despite these changes, the preferences of medical students and anatomy faculty towards both traditional and contemporary teaching methods and tools are largely unknown. This study quantified medical student and anatomy faculty opinion on various aspects of anatomical teaching at the Department of Anatomy, University of Bristol, UK. A questionnaire was used to explore the perceived effectiveness of different anatomical teaching methods and tools among anatomy faculty (AF) and medical students in year one (Y1) and year two (Y2). A total of 370 preclinical medical students entered the study (76% response rate). Responses were quantified and intergroup comparisons were made. All students and AF were strongly in favor of access to cadaveric specimens and supported traditional methods of small-group teaching with medically qualified demonstrators. Other teaching methods, including e-learning, anatomical models and surgical videos, were considered useful educational tools. In several areas there was disharmony between the opinions of AF and medical students. This study emphasizes the importance of collecting student preferences to optimize teaching methods used in the undergraduate anatomy curriculum. © 2013 American Association of Anatomists.

Drawing on student knowledge in human anatomy and physiology

NASA Astrophysics Data System (ADS)

Slominski, Tara Nicole

Prior to instruction, students may have developed alternative conceptions about the mechanics behind human physiology. To help students re-shape these ideas into correct reasoning, the faulty characteristics reinforcing the alternative conceptions need to made explicit. This study used student-generated drawings to expose alternative conceptions Human Anatomy and Physiology students had prior to instruction on neuron physiology. Specifically, we investigated how students thought about neuron communication across a synapse (n=355) and how neuron activity can be modified (n=311). When asked to depict basic communication between two neurons, at least 80% of students demonstrated incorrect ideas about synaptic transmission. When targeting spatial and temporal summation, only eleven students (3.5%) were able to accurately depict at least one form of summation. In response to both drawing questions, student drawings revealed multiple alternative conceptions that resulted in a deeper analysis and characterization of the wide variation of student ideas.

In teaching and learning human anatomy, anatomical autopsy and prosected specimens have always been indispensable. However, alternative methods must often be used to demonstrate particularly delicate structures. Corrosion casting of porcine organs with Biodur E20 ® Plus is valuable for teaching and learning both gross anatomy and, uniquely, the micromorphology of cardiovascular, respiratory, digestive, and urogenital systems. Assessments of casts with a stereomicroscope and/or scanning electron microscope as well as highlighting cast structures using color coding help students to better understand how the structures that they have observed as two-dimensional images actually exist in three dimensions, and students found using the casts to be highly effective in their learning. Reconstructions of cast hollow structures from (micro-)computed tomography scans and videos facilitate detailed analyses of branching patterns and spatial arrangements in cast structures, aid in the understanding of clinically relevant structures and provide innovative visual aids. The casting protocol and teaching manual we offer can be adjusted to different technical capabilities and might also be found useful for veterinary or other biological science classes.

The greater expansion of the frontal lobes along the phylogeny scale has been interpreted as the signature of evolutionary changes underlying higher cognitive abilities in humans functions in humans. However, it is unknown how an increase in number of gyri, sulci and cortical areas in the frontal lobe have coincided with a parallel increase in connectivity. Here, using advanced tractography based on spherical deconvolution, we produced an atlas of human frontal association connections that we compared with axonal tracing studies of the monkey brain. We report several similarities between human and monkey in the cingulum, uncinate, superior longitudinal fasciculus, frontal aslant tract and orbito-polar tract. These similarities suggest to preserved functions across anthropoids. In addition, we found major differences in the arcuate fasciculus and the inferior fronto-occipital fasciculus. These differences indicate possible evolutionary changes in the connectional anatomy of the frontal lobes underlying unique human abilities. Copyright © 2011 Elsevier Srl. All rights reserved.

In nursing education, the personal computer and the Internet facilitate teaching theoretical and practical knowledge. Evaluate an educational technology known as "Anatomy and Vital Signs" with respect to content, appearance and usability. This was a first stage evaluation-by specialists to verify content and functioning, prior to a second validation as to learning by students. A methodological study in which instructional technologists (11 participants) and nursing specialists (17 participants) used the technology in an unguided manner and completed three questionnaires. The evaluation was measured by the difference between disagreement and agreement for each statement in the questionnaires. Most of the items were positively evaluated at a level higher than 70% by most of the evaluators except for the following usability criteria: grouping by shape, minimum actions and user control, which did not attain the 70% agreement level among instructional technologists. The evaluation was useful to improve the technology and guarantee suitable product for nursing education.

The anatomy of the human body based on a special teleological system is one of the greatest miracles of the world. The skull's primary function is the defence of the brain, so every alteration or disease of the brain results in some alteration of the skull. This analogy is to be identified even in the human embryo. Proportions of the 22 bones constituting the skull and of sizes of sutures are not only the result of the phylogeny, but those of the ontogeny as well. E.g. the age of the skeletons in archaeological findings could be identified according to these facts. Present paper outlines the ontogeny and development of the tissues of the skull, of the structure of the bone-tissue, of the changes of the size of the skull and of its parts during the different periods of human life, reflecting to the aesthetics of the skull as well. "Only the human scull can give me an impression of beauty. In spite of all genetical colseness, a skull of a chimpanzee cannot impress me aesthetically"--author confesses. In the second part of the treatise those authors are listed, who contributed to the perfection of our knowledge regarding the skull. First of all the great founder of modern anatomy, Andreas Vesalius, then Pierre Paul Broca, Jacob Benignus Winslow are mentioned here. The most important Hungarian contributors were as follow: Sámuel Rácz, Pál Bugát or--the former assistant of Broca--Aurél Török. A widely used tool for measurement of the size of the skull, the craniometer was invented by the latter. The members of the family Lenhossék have had also important results in this field of research, while descriptive anatomy of the skull was completed by microsopical anatomy thanks the activity of Géza Mihálkovits.

Introduction This paper describes the design, implementation, and potential use of a comparative anatomy information system (CAIS) for querying on similarities and differences between homologous anatomical structures across species, the knowledge base it operates upon, the method it uses for determining the answers to the queries, and the user interface it employs to present the results. The relevant informatics contributions of our work include (1) the development and application of the structural difference method, a formalism for symbolically representing anatomical similarities and differences across species; (2) the design of the structure of a mapping between the anatomical models of two different species and its application to information about specific structures in humans, mice, and rats; and (3) the design of the internal syntax and semantics of the query language. These contributions provide the foundation for the development of a working system that allows users to submit queries about the similarities and differences between mouse, rat, and human anatomy; delivers result sets that describe those similarities and differences in symbolic terms; and serves as a prototype for the extension of the knowledge base to any number of species. Additionally, we expanded the domain knowledge by identifying medically relevant structural questions for the human, the mouse, and the rat, and made an initial foray into the validation of the application and its content by means of user questionnaires, software testing, and other feedback. Methods The anatomical structures of the species to be compared, as well as the mappings between species, are modeled on templates from the Foundational Model of Anatomy knowledge base, and compared using graph-matching techniques. A graphical user interface allows users to issue queries that retrieve information concerning similarities and differences between structures in the species being examined.

Human trafficking is a major global public health concern. It is a grave crime that violates human rights. Contrary to healthcare providers' perceptions, victims of human trafficking come in contact with the healthcare system while being trafficked, with the emergency department being the most frequented setting for medical treatment. In this article, we explore the anatomy of human trafficking, including the scope of the problem, definitions, and types and elements of human trafficking. The roles of clinicians, particularly emergency department nurses and advanced practice nurses, in screening and identifying those at risk are examined. Clinical practice tools and guidelines that may be used by clinicians to guide the treatment of human trafficking victims are reviewed. Finally, current strategies and resources that address human trafficking are presented. For the purpose of this article, the terms "human trafficking" or "trafficking" will be used throughout.

The study was carried out to determine the content of mercury in bone tissue of the proximal femur (head and neck bone) of 95 patients undergoing total hip replacement due to osteoarthritis, using CF-AFS analytical technique. Furthermore, the investigations were aimed at assessing the impact of selected factors, such as age, gender, tobacco smoking, alcohol consumption, exposure to chemical substance at work, type of degenerative changes, clinical evaluation and radiological parameters, type of medications, on the concentration of mercury in the head and neck of the femur, resected in situ. Mercury was obtained in all samples of the head and neck of the femur (n = 190) in patients aged 25-91 years. The mean content of mercury for the whole group of patients was as follows: 37.1 ± 35.0 ng/g for the femoral neck and 24.2 ± 19.5 ng/g for the femoral head. The highest Hg contents were found in femoral neck samples, both in women and men, and they amounted to 169.6 and 176.5 ng/g, respectively. The research showed that the mercury content of bones can be associated with body mass index, differences in body anatomy, and gender. The uses of statistical analysis gave the possibility to define the influence of factors on mercury content in human femoral bones.

Three-dimensional (3D) digital animations were used to teach the human musculoskeletal system to first year kinesiology students. The purpose of this study was to assess the effectiveness of this method by comparing two groups from two different academic years during two of their official required anatomy examinations (trunk and upper limb assessments). During the upper limb section, the teacher used two-dimensional (2D) drawings embedded into PowerPoint(®) slides and 3D digital animations for the first group (2D group) and the second (3D group), respectively. The same 3D digital animations were used for both groups during the trunk section. The only difference between the two was the multimedia used to present the information during the upper limb section. The 2D group surprisingly outperformed the 3D group on the trunk assessment. On the upper limb assessment no difference in the scores on the overall anatomy examination was found. However, the 3D group outperformed the 2D group in questions requiring spatial ability. Data supported that 3D digital animations were effective instructional multimedia material tools in teaching human anatomy especially in recalling anatomical knowledge requiring spatial ability. The importance of evaluating the effectiveness of a new instructional material outside laboratory environment (e.g., after a complete semester and on official examinations) was discussed. © 2014 American Association of Anatomists.

The caecocolonic junction in humans has a sphincteric anatomy and function.

Sphincteric anatomy and function are present at the caecocolonic junction in several mammals. In humans, radiologists and endoscopists have respectively reported a circumferential contraction and a prominent ileocaecal fold at the border area between the caecum and the ascending colon. Anatomical findings on necropsy material failed to confirm its presence. Microscopic studies on surgical specimens showed the existence of muscular and innervational patterns different from those of adjacent areas. The aim of this work was to confirm the existence of a specialised fold at the caecocolonic junction in humans and to ascertain its role by carrying out a study of functional anatomy. Pancolonoscopies were performed on 100 patients and ileocaecal fold behaviour was observed before and after mechanical stimulation. Isolated ileocaecocolonic regions, surgically obtained, were filled with a fixative solution to study their macro and microscopic morphology after stimulation. Endoscopically, the ileocaecal fold was semilunar or circular in shape and spontaneous or evoked spasms occurred in 52 patients. A prominent circular fold could be seen in surgical specimens after stimulation. The entire muscle coat deeply penetrated this fold, showing the features characteristic of the ileocaecal junction. In particular, the inner portion of the circular muscle showed a peculiar arrangement and was thicker than elsewhere. These results show that in humans the caecocolonic junction is provided with a sphincter morphology and function. Little is known about its physiological relevance in ileal flow accommodation and caecal filling and emptying but it should not be underestimated with regard to some colonic motility disorders.

2011-01-01

This paper is concerned with the analysis of the use of Latin terms in the field of human anatomy through the contrastive analysis of examples from anatomy atlases and textbooks, and research papers in the area of human anatomy in English and Serbian. The contrastive analysis of examples has highlighted a certain tendency towards the use of original Latin terms in anatomy literature in the Serbian language, while the tendency of anatomy literature in English is towards the use of English terms which most often have a Latin root. It has also been noted that Serbian literature, in addition to original Latin terms, uses a significant number of terms with a Latin root. The noted tendencies differ depending on the type of literature (anatomy atlas, textbook or research paper). A significantly greater uniformity in the use of terminology has been noted in editions in English as compared to the Serbian anatomy literature where a lack of such a uniform system is evident. Bearing in mind the ever increasing significance of the English language in the world of science, one of the conclusions of this paper is that these differences may be of practical significance for authors from Serbia looking to publish their work in English as well as for translators of medical literature.

This study presents the design, effect and utility of using audiovisual material containing real images of dissected human cadavers as an innovative educational strategy (IES) in the teaching of Human Anatomy. The goal is to familiarize students with the practice of dissection and to transmit the importance and necessity of this discipline, while modulating their anxiety. The study included 303 first-year Human Anatomy students, randomly assigned to two groups (Traditional and Educational Innovation). Their state of anxiety was measured using the State-Trait-Anxiety Inventory. Repeated measures ANOVA with between-subject factors was applied. The between-subject factor was Educational Innovation (EI). Two levels were established for this factor. The within-subject factor was Time, four levels being considered here. The results show that the effects of the Educational Innovation factor, Time factor and EI × Time interaction were statistically significant. These results provide an additional element of efficacy to the use of videos as an IES. That is, the use of video material as an introduction into an anxiety-provoking situation which resembles real-life viewing and interaction with human cadavers for the first time significantly diminishes the anticipatory reaction of dread against which novel students have not had the opportunity to develop any cognitive strategy of emotional control.

This study was designed to assess the grades, self-perceived learning, and satisfaction between occupational therapy students who used a gross anatomy laboratory versus online anatomy software (AnatomyTV) as tools to learn anatomy at a large public university and a satellite campus in the mid-western United States. The goal was to determine if equivalent learning outcomes could be achieved regardless of learning tool used. In addition, it was important to determine why students chose the gross anatomy laboratory over online AnatomyTV. A two group, post-test only design was used with data gathered at the end of the course. Primary outcomes were students' grades, self-perceived learning, and satisfaction. In addition, a survey was used to collect descriptive data. One cadaver prosection was available for every four students in the gross anatomy laboratory. AnatomyTV was available online through the university library. At the conclusion of the course, the gross anatomy laboratory group had significantly higher grade percentage, self-perceived learning, and satisfaction than the AnatomyTV group. However, the practical significance of the difference is debatable. The significantly greater time spent in gross anatomy laboratory during the laboratory portion of the course may have affected the study outcomes. In addition, some students may find the difference in (B+) versus (A-) grade as not practically significant. Further research needs to be conducted to identify what specific anatomy teaching resources are most effective beyond prosection for students without access to a gross anatomy laboratory. © 2015 American Association of Anatomists.

An Interactive 3D Virtual Anatomy Puzzle for Learning and Simulation - Initial Demonstration and Evaluation.

2016-01-01

To inspire young students (grades 6-12) to become medical practitioners and biomedical engineers, it is necessary to expose them to key concepts of the field in a way that is both exciting and informative. Recent advances in medical image acquisition, manipulation, processing, visualization, and display have revolutionized the approach in which the human body and internal anatomy can be seen and studied. It is now possible to collect 3D, 4D, and 5D medical images of patient specific data, and display that data to the end user using consumer level 3D stereoscopic display technology. Despite such advancements, traditional 2D modes of content presentation such as textbooks and slides are still the standard didactic equipment used to teach young students anatomy. More sophisticated methods of display can help to elucidate the complex 3D relationships between structures that are so often missed when viewing only 2D media, and can instill in students an appreciation for the interconnection between medicine and technology. Here we describe the design, implementation, and preliminary evaluation of a 3D virtual anatomy puzzle dedicated to helping users learn the anatomy of various organs and systems by manipulating 3D virtual data. The puzzle currently comprises several components of the human anatomy and can be easily extended to include additional organs and systems. The 3D virtual anatomy puzzle game was implemented and piloted using three display paradigms - a traditional 2D monitor, a 3D TV with active shutter glass, and the DK2 version Oculus Rift, as well as two different user interaction devices - a space mouse and traditional keyboard controls.

A traditional lecture-based pedagogy conveys information and content while lacking sufficient development of critical thinking skills and problem solving. A puzzle-based pedagogy creates a broader contextual framework, and fosters critical thinking as well as logical reasoning skills that can then be used to improve a student's performance on content specific assessments. This paper describes a pedagogical comparison of traditional lecture-based teaching and puzzle-based teaching in a Human Anatomy and Physiology II Lab. Using a single subject/cross-over design half of the students from seven sections of the course were taught using one type of pedagogy for the first half of the semester, and then taught with a different pedagogy for the second half of the semester. The other half of the students were taught the same material but with the order of the pedagogies reversed. Students' performance on quizzes and exams specific to the course, and in-class assignments specific to this study were assessed for: learning outcomes (the ability to form the correct conclusion or recall specific information), and authentic academic performance as described by (Am J Educ 104:280-312, 1996). Our findings suggest a significant improvement in students' performance on standard course specific assessments using a puzzle-based pedagogy versus a traditional lecture-based teaching style. Quiz and test scores for students improved by 2.1 and 0.4% respectively in the puzzle-based pedagogy, versus the traditional lecture-based teaching. Additionally, the assessments of authentic academic performance may only effectively measure a broader conceptual understanding in a limited set of contexts, and not in the context of a Human Anatomy and Physiology II Lab. In conclusion, a puzzle-based pedagogy, when compared to traditional lecture-based teaching, can effectively enhance the performance of students on standard course specific assessments, even when the assessments only test a limited

The development of interactive online learning tools for the study of anatomy.

The study of human anatomy is a core component of health science programs. However large student enrolments and the content-packed curricula associated with these programs have made it difficult for students to have regular access to cadaver laboratories. Adobe Flash MXwas used with cadaver digital photographs and textbook-derived illustrations to develop interactive anatomy images that were made available to undergraduate health science students enrolled in first-year combined anatomy and physiology (ANP) courses at the University of Ottawa. Colour coding was used to direct student attention, facilitate name-structure association, improve visualization of structure contours, assist students in the construction of anatomical pathways, and to reinforce functional or anatomical groupings. The ability of two-dimensional media to support the visualization of three-dimensional structure was extended by developing the fade-through image (students use a sliding bar to move through tissues) as well as the rotating image in which entire organs such as the skull were photographed at eight angles of rotation. Finally, students were provided with interactive exercises that they could repeatedly try to obtain immediate feedback regarding their learning progress. Survey data revealed that the learning and self-testing tools were used widely and that students found them relevant and supportive of their self-learning. Interestingly, student summative examination outcomes did not differ between those students who had access to the online tools and a corresponding student group from the previous academic year who did not. Interactive learning tools can be tailored to meet program-specific learning objectives as a cost-effective means of facilitating the study of human anatomy. Virtual interactive anatomy exercises provide learning opportunities for students outside the lecture room that are of especial value to visual and kinesthetic learners.

This study provides a systematic assessment of different methods of delivering radiologic teaching content (lecture, printed text, and digital content delivery) under standard conditions, enabling comparison of the effectiveness of these methods. A printed atlas of sectional anatomy was used as a standard. Digital content was developed on the basis of the printed atlas. Lecturers used both the printed and the digital content to prepare lectures. Standardized teaching material thus created was presented to second-term undergraduate students who had attended the school's anatomy course, but had not received any radiology teaching. Multiple choice examinations were used to assess the students' ability to recognize anatomical structures in known as well as unknown images. In a survey, the students' subjective experience of the learning process was assessed. No difference was seen between the groups regarding examination results. Students preferred a combination of digital media and lectures by enthusiastic teachers. The shortage of teachers requires a compromise concerning the delivery of radiologic anatomy content in a medical school setting. Based on our results, we recommend a combined approach of lecture and digital content delivery.

Tricuspid regurgitation may be a precursor for heart failure, reduced functional capacity, and poor survival. A human compatible experimental model is required to understand the pathophysiology of the tricuspid valve disease as a basis for validating novel tricuspid valve interventions before clinical use. The study aim was to evaluate and compare the tricuspid valve anatomy of porcine and human hearts. The anatomy of the tricuspid valve and the surrounding structures that affect the valve during a cardiac cycle were examined in detail in 100 fresh and 19 formalin-fixed porcine hearts obtained from Danish Landrace pigs (body weight 80 kg). All valvular dimensions were compared with human data acquired from literature sources. No difference was seen in the tricuspid annulus circumference between porcine and human hearts (13.0 ± 1.2 cm versus 13.5 ± 1.5 cm; p = NS), or in valve area (5.7 ± 1.6 cm2 versus 5.6 ± 1.0 cm2; p = NS). The majority of chordae types exhibited a larger chordal length and thickness in human hearts compared to porcine hearts. In both species, the anterior papillary muscle (PM) was larger than other PMs in the right ventricle, but muscle length varied greatly (range: 5.2-40.3 mm) and was significantly different in pigs and in humans (12.2 ± 3.2 mm versus 19.2 mm; p <0.001). The porcine tricuspid valve was determined to be a valid model for preclinical animal studies, despite various anatomic differences being noted between porcine and human hearts.

Learning by lecture is a passive experience. Many innovative techniques have been presented to stimulate students to assume a more active attitude toward learning. In this study, simultaneous sketch drawing, as an interactive learning technique was applied to teach anatomy to the medical students. We reconstructed a fun interactive model of teaching anatomy as simultaneous anatomic sketching. To test the model's instruction effectiveness, we conducted a quasi- experimental study and then the students were asked to write their learning experiences in their portfolio, also their view was evaluated by a questionnaire. The results of portfolio evaluation revealed that students believed that this method leads to deep learning and understanding anatomical subjects better. Evaluation of the students' views on this teaching approach was showed that, more than 80% of the students were agreed or completely agreed with this statement that leaning anatomy concepts are easier and the class is less boring with this method. More than 60% of the students were agreed or completely agreed to sketch anatomical figures with professor simultaneously. They also found the sketching make anatomy more attractive and it reduced the time for learning anatomy. These number of students were agree or completely agree that the method help them learning anatomical concept in anatomy laboratory. More than 80% of the students found the simultaneous sketching is a good method for learning anatomy overall. Sketch drawing, as an interactive learning technique, is an attractive for students to learn anatomy.

Dissection courses in human anatomy are laborious, and new teaching tools have become available. Therefore, some universities intend to reduce the dissection course. Furthermore, little is known about dissection courses in African universities. The aim of this study is to compare the students' experiences with and evaluations of the dissection courses in two universities: Leipzig (Germany) and Gondar (Ethiopia). Since the Gondar Medical College was founded in cooperation with the Leipzig University in 1978, the anatomy courses in both universities follow roughly the same rules. A structured questionnaire was used to assess the dissection courses from the students' point of view. The sample of students consisted of 109 German and 124 Ethiopian first year undergraduate medical students. Most students in both countries (94% in Germany and 82% in Ethiopia) judge the dissection course to be highly relevant compared to other courses. Perceived health hazards associated with dissection of the cadaver show significant differences between Germany (14%) and Ethiopia (44%). Most students had normal feelings again at the end of the dissection course. Further similarities and differences between the courses in Germany and Ethiopia are described. Dissection courses are highly appreciated also in Africa. The high degree of affirmation of the dissection courses should be taken into consideration when discussing modifications of gross anatomy curriculum or changes in the teacher to student ratio.

Macaque monkeys are used in many research applications, including cerebrovascular investigations. However, detailed catalogs of the relevant vascular anatomy are scarce. We present our experience with macaque vessel patterns as determined by digital subtraction angiography of 34 different monkeys. We retrospectively analyzed digital subtraction angiograms obtained during experimental internal carotid artery (ICA) catheterization and subsequent injection of 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine. Results were catalogued according to vascular distribution and variants observed. Macaque monkeys have a bovine aortic arch. The carotid vessels generally bifurcate, but are occasionally observed to divide into three vessels. The external carotid gives rise primarily to two trunks: an occipital branch and a common vessel that subsequently gives off the lingual, facial, and superior thyroid arteries. The internal maxillary artery may be present as a terminal branch of the external carotid or as a branch of the occipital artery. The ICA is similar in course to that of the human. The anterior circle of Willis was intact in all monkeys in our study. Its primary difference from that of the human is the union of the bilateral anterior cerebral arteries as a single (azygous) median vessel. Macaque cervical carotid and circle of Willis arterial anatomy differs from humans in a couple of specific patterns. Knowledge of these differences and similarities between human and macaque anatomy is important in developing endovascular macaque models of human diseases, such as ischemic stroke.

Links between Evolution, Development, Human Anatomy, Pathology, and Medicine, with A Proposition of A Re-defined Anatomical Position and Notes on Constraints and Morphological "Imperfections".

PubMed

Diogo, Rui; Molnar, Julia

2016-06-01

Surprisingly the oldest formal discipline in medicine (anatomy) has not yet felt the full impact of evolutionary developmental biology. In medical anatomy courses and textbooks, the human body is still too often described as though it is a "perfect machine." In fact, the study of human anatomy predates evolutionary theory; therefore, many of its conventions continue to be outdated, making it difficult to study, understand, and treat the human body, and to compare it with that of other, nonbipedal animals, including other primates. Moreover, such an erroneous view of our anatomy as "perfect" can be used to fuel nonevolutionary ideologies such as intelligent design. In the section An Evolutionary and Developmental Approach to Human Anatomical Position of this paper, we propose the redefinition of the "human standard anatomical position" used in textbooks to be consistent with human evolutionary and developmental history. This redefined position also simplifies, for students and practitioners of the health professions, the study and learning of embryonic muscle groups (each group including muscles derived from the same/ontogenetically closely related primordium/primordia) and joint movements and highlights the topological correspondence between the upper and lower limbs. Section Evolutionary and Developmental Constraints, "Imperfections" and Sports Pathologies continues the theme by describing examples of apparently "illogical" characteristics of the human body that only make sense when one understands the developmental and evolutionary constraints that have accumulated over millions of years. We focus, in particular, on musculoskeletal functional problems and sports pathologies to emphasize the links with pathology and medicine. These examples demonstrate how incorporating evolutionary theory into anatomy education can be helpful for medical students, teachers, researchers, and physicians, as well as for anatomists, functional morphologists, and evolutionary and

2017-01-01

Understanding basic human anatomy can be beneficial for all students, regardless of when, or if, they will later undertake a formal course in the subject. For students who are preparing to undertake a formal anatomy course, educational comics on basic anatomy can serve as a concise and approachable review of the material. For other students, these comics can serve as a helpful and fun introduction to the human body. The objective of the comics in this study was to promote an understanding of fundamental human anatomy through self-learning among students. Based on the authors' previous teaching experience, these anatomy comics were produced in a simple, direct style. The comics were titled after the two main characters, "Anna" (a girl) and "Tommy" (a boy). These comics were then presented to groups of elementary school students, high school students, premedical students, and medical students to assess the comics' ability to enhance student interest and comprehension of basic anatomy. Quiz scores among high school students and premedical students were significantly higher among participants who read the educational comics, indicating a deeper comprehension of the subject. Among medical students, close reading of the comics was associated with improved course grades. These educational anatomy comics may be helpful tools to enrich a broad spectrum of different students in learning basic human anatomy.

We have developed a novel method to describe human white matter anatomy using an approach that is both intuitive and simple to use, and which automatically extracts white matter tracts from diffusion MRI volumes. Further, our method simplifies the quantification and statistical analysis of white matter tracts on large diffusion MRI databases. This work reflects the careful syntactical definition of major white matter fiber tracts in the human brain based on a neuroanatomist’s expert knowledge. The framework is based on a novel query language with a near-to-English textual syntax. This query language makes it possible to construct a dictionary of anatomical definitions that describe white matter tracts. The definitions include adjacent gray and white matter regions, and rules for spatial relations. This novel method makes it possible to automatically label white matter anatomy across subjects. After describing this method, we provide an example of its implementation where we encode anatomical knowledge in human white matter for ten association and 15 projection tracts per hemisphere, along with seven commissural tracts. Importantly, this novel method is comparable in accuracy to manual labeling. Finally, we present results applying this method to create a white matter atlas from 77 healthy subjects, and we use this atlas in a small proof-of-concept study to detect changes in association tracts that characterize schizophrenia.

The public display of plastinates as a challenge to the integrity of anatomy.

PubMed

Jones, David Gareth

2016-01-01

Anatomy has been thrust into the public domain by the highly successful public displays of dissected and plastinated human bodies. This is anatomy in modern guise, anatomy as perceived by the general public. If this is the case, the message it is giving the public about the nature of anatomy is that it is an impersonal analysis of the human body of value within a medical and health care environment. While this is in part true, and while it reflects important aspects of anatomy's history, it fails to reflect the humanistic strands within an increasing swathe of contemporary anatomy. These are manifested in growing recognition of the centrality of informed consent in the practice of anatomy, awareness of the personal dimensions and relationships of those whose bodies are being dissected, and manifested in thanksgiving ceremonies involving staff and students. The notion that the bodies undergoing dissection can be students' first teachers and/or patients is gaining ground, another indication of the human dimensions of the anatomical enterprise. Exhibitions such as Body Worlds ignore these dimensions within anatomy by dislocating it from its clinical and relational base. The significance of this is that loss of these dimensions leads to a loss of the human face of anatomy by isolating it from the people whose body bequests made this knowledge possible. What is required is greater transparency and openness in the practices of all who deal with the dead human body, trends that owe much to the writings of scholars from within a range of humanities disciplines as they have responded to the public displays of dissected plastinated bodies. Anatomists have much to learn from these debates. © 2015 Wiley Periodicals, Inc.

Ever since man started to study systematically medicine for the first time he recognized the value of the knowledge of Anatomy in order to safely cut and treat the human body. However, over the centuries it has been proved that Anatomy is more than just a scientific field of medicine. The fact that Anatomy requires the use of human cadavers as an object to study brought to the surface many moral issues, which adumbrated its turbulent past. Additionally, Anatomy and its inextricable element, illustration, has many times been a source of inspiration for both the anatomists and the artists. This paper aims on the one hand to provide a condensed overview of the history of Anatomy and on the other hand to investigate the way Anatomy penetrates Art and, conversely, Art penetrates Anatomy.

Online instructional anatomy videos: Student usage, self-efficacy, and performance in upper limb regional anatomy assessment.

2017-12-04

Allied health professionals concur that a sound knowledge of practical gross anatomy is vital for the clinician, however, human anatomy courses in allied health programs have been identified as high-risk for attrition and failure. While anatomists and clinicians agree that learning anatomy via human cadaveric instruction is the preferred method, students vary in their reaction to the cadaveric learning experience and have differing levels of anatomy self-efficacy. This study investigated whether student self-efficacy had an effect on student usage of supplemental instructional videos and whether the use of videos had an impact on student self-efficacy and/or learning. Anatomy self-efficacy differed based on gender and prior performance. Student usage of the videos varied widely and students with lower self-efficacy were more inclined to use the resources. The provision of the videos did not improve overall cohort performance as compared to a historical cohort, however, those students that accessed all video sets experienced a greater normalized learning gain compared to students that used none or one of the four sets of videos. Student reports and usage patterns indicate that the videos were primarily used for practical class preparation and revision. Potentially, the videos represent a passive mode of teaching whereas active learning has been demonstrated to result in greater learning gains. Adapting the videos into interactive tutorials which will provide opportunity for feedback and the development of students' self-evaluation may be more appropriate.

[History of anatomy in Strasbourg].

PubMed

Le Minor, J M; Kahn, J L

1989-01-01

When printing came into being, Strasbourg played a crucial role in the dissemination of the knowledge on anatomy, especially with the publication of Brunschwig's famous treatise on surgery in 1497. The first official human dissection in Strasbourg was performed in 1517. The teaching of medicine really began with the establishment of the Academy in 1566, but it was only in 1652 that a specific chair was created for anatomy. The first anatomical theatre was opened in 1670 in a secularized church contiguous to the city hospital. Until 1708, the teaching of anatomy is combined with that of botany; it was only from this date that anatomy was to be associated with surgery, and such was the case until the French Revolution. During the nineteenth century an impressive museum of anatomy was gradually established in Strasbourg. In 1872, after the annexation of Alsace, when the new german university was created, normal and pathological anatomy were separated and each chair attached to a particular institute. The building housing the institutes of normal and pathological anatomy was inaugurated in 1877 and is still used today. In 1919, when the Faculty of medicine was reorganized after Alsace was restored to France, histology and embryology were definitively separated from anatomy. Many famous anatomists worked in Strasbourg, among whom are to be found: J. G. von Andernach (1497-1574), T. Lauth (1758-1826), F. D. Reisseissen (1773-1828), J. F. Lobstein (1777-1835), E. A. Lauth (1803-1837), E. Küss (1815-1871), E. Koeberlé (1828-1915), E. Beaunis (1830-1921), H. D. Bouchard (1833-1899), J. G. Joessel (1838-1892), W. Waldeyer (1836-1921), G. Schwalbe (1844-1916), W. Pfitzner (1853-1903), F. Keibel (1861-1929), A. Forster (1878-1957) and Ph. Bellocq (1888-1962).

Five hundred students attending higher education institutions in northeastern Brazil responded to questionnaires about their anatomy classes; students represented a variety of different health sciences disciplines. Analysis of the responses revealed the participation of teaching assistants in a large percentage of classes and the use of teaching resources, particularly images, from conventional radiographs to magnetic resonance images. The number of classes for cadaver dissection and the number of students with access to that type of class were small. In most cases, dissection was performed according to anatomic regions or systems. Medicine and nursing students had the highest number of practical dissection classes. Most students were assessed using practical and theoretical tests. Findings revealed conditions similar to those found elsewhere. Resources should be renewed and used to improve teaching for students whose courses demand the study of human anatomy.

This study investigates differences in the anatomy of male and female knee joints to contribute to the current debate on sex-specific total knee implants. Morphometric data were obtained from 60 human cadaver knees, and sex differences were calculated. All data were corrected for height, and male and female specimens presenting with an identical length of the femur were analyzed as matched pairs. Male linear knee joint dimensions were significantly larger when compared with females. When corrected for differences in height, medial-lateral dimensions of male knees were significantly larger than female; however, matched paired analysis did not prove these differences to be consistent. Although implant design should focus interindividual variations in knee joint anatomy, our data do not support the concept of a female-specific implant design. Copyright © 2011 Elsevier Inc.

Imaging in anatomy: a comparison of imaging techniques in embalmed human cadavers

PubMed Central

2013-01-01

Background A large variety of imaging techniques is an integral part of modern medicine. Introducing radiological imaging techniques into the dissection course serves as a basis for improved learning of anatomy and multidisciplinary learning in pre-clinical medical education. Methods Four different imaging techniques (ultrasound, radiography, computed tomography, and magnetic resonance imaging) were performed in embalmed human body donors to analyse possibilities and limitations of the respective techniques in this peculiar setting. Results The quality of ultrasound and radiography images was poor, images of computed tomography and magnetic resonance imaging were of good quality. Conclusion Computed tomography and magnetic resonance imaging have a superior image quality in comparison to ultrasound and radiography and offer suitable methods for imaging embalmed human cadavers as a valuable addition to the dissection course.

2012-09-01

The purpose of this study was to evaluate the effectiveness of online mastery quizzes in enhancing dental students' learning and preparedness for anatomy examinations. First-year dental students taking an integrated anatomy course at The Ohio State University were administered online mastery quizzes, made available for five days before each examination. The mastery quizzes were comprised of ten multiple-choice questions representative of the upcoming examination in content and difficulty. The students were allowed to access this resource as many times as they desired during the five-day window before each examination; the highest score for each student was added to his or her final course grade. The results indicate that almost all the students took advantage of this resource to reinforce content, clarify concepts, and prepare for the examinations. Statistical analyses of the students' exam performance showed that the mastery quizzes neither improved nor reduced their exam scores, but multiple regression analyses showed that the initial mastery quiz scores had a predictive value for their examination performance, suggesting a potential for mastery quizzes as an intervention tool for such a course. Online mastery quizzes, when used effectively, may be an effective resource to further engage dental and other students in educational endeavors and examination preparation and as a predictor of success.

Knowledge of gross anatomy, as a basic core subject, is fundamental for medical students and essential to medical practitioners, particularly for those intending a surgical career. However, both medical students and clinical teachers have found a significant gap in teaching basic sciences and the transition into clinical skills. The authors present a Surgical Anatomy Course developed to teach the anatomical basis of surgical procedures with particular emphasis on laparo-scopic skills while incorporating medical simulation. An evaluation of the students' satisfaction of the Surgical Anatomy Course was completed using a mix of multiple choice and open-ended questions, and a six-point Likert Scale. Questions were asked about the students' perceived improvement in surgical and laparoscopic skills. Manual skills were assessed using a laparoscopic simulator. Both evaluation of the course structure and the general impression of the course were positive. Most students believed the course should be an integral part of a modern curriculum. The course supported the traditional surgical classes and improved anatomical knowledge and strengthened students' confidentiality and facilitated understanding and taking surgical rotations. A medical course combining the practical learning of anatomy and surgical-based approaches will bring out the best from the students. Medical students positively evaluated the Surgical Anatomy Course as useful and benefi-cial regarding understanding anatomical structure and relationship necessary for further surgical education.

Body Worlds is an anatomical exhibition that shows human remains to the public. It has been considered controversial since it raises ethical tensions and issues. However, organizers and supporters of Body Worlds have claimed the exhibition is intended to promote visitors' understanding over the human body. Despite these claims, no studies were found that support or refute the hypothesis that a visit to Body Worlds increases the public's objective knowledge on human anatomy. Consequently, the objective of this study was to determine the impact of Body Worlds on anatomical knowledge. We constructed and delivered a questionnaire to both a previsit random sample and a postvisit random sample of visitors of Body Worlds' event Facets of Life, in Berlin. The questionnaire was available in both English and German languages and contained (a) basic sociodemographic questions and (b) a valid and reliable anatomy quiz. The quiz consisted of 16 multiple-choice questions that assessed the ability to identify the location of major anatomical structures on the human body. Average scores achieved on the quiz by the postvisit sample (X¯= 9.08, s = 2.48, n = 164) were significantly higher (unpaired t = 3.3957, P = 0.0008) than those achieved by the previsit sample (X¯= 8.11, s = 2.69, n = 167). Our results suggest that a visit to Body Worlds' event Facets of Life may have a beneficial effect in anatomical knowledge. However, further studies with better empirical designs and fewer limitations are needed to confirm our results. © 2016 Wiley Periodicals, Inc.

Formalin had traditionally been used to preserve human material to teach gross anatomy. In 2008 the Centre for Anatomy and Human Identification (CAHID) at the University of Dundee embarked on the use of the Thiel method of embalming. The aim of this pilot study was to assess the difference between formalin-embalmed cadavers (FEC) and Thiel-embalmed cadavers (TEC) used for teaching and surgical training. Three different questionnaires were prepared for data collection from undergraduate and postgraduate students and clinical staff. All undergraduate and postgraduate students as well as clinical staff commented on the appearance of the TEC. There was no overall consensus concerning the use of TEC, some respondents preferred TEC for the entire dissection, some only for certain areas such as the musculoskeletal system. On a technical level TEC were considered less hazardous then FEC by one-third of participants with fewer than 10% regarding TEC as more irritating than FEC. Psychologically, 32.7% of undergraduate students expressed the view that TEC made them feel more uncomfortable compared with FEC because of their life-like appearance. However, 57.1% of undergraduate students encountered the same uncomfortable feelings when viewing both TEC and FEC. The use of Thiel-embalmed cadavers to teach anatomy has an added value, though further research is required over longer periods of time to identify its best usage. © 2014 American Association of Anatomists.

Educators must select the best tools to teach anatomy to future physicians and traditionally, cadavers have always been considered the "gold standard" simulator for living anatomy. However, new advances in technology and radiology have created new teaching tools, such as virtual dissection, which provide students with new learning opportunities. Virtual dissection is a novel way of studying human anatomy through patient computed tomography (CT) scans. Through touchscreen technology, students can work together in groups to "virtually dissect" the CT scans to better understand complex anatomic relationships. This article presents the anatomic and pedagogic limitations of cadaveric dissection and explains what virtual dissection is and how this new technology may be used to overcome these limitations.

Current undergraduate medical school curricular trends focus on both vertical integration of clinical knowledge into the traditionally basic science-dedicated curricula and increasing basic science education in the clinical years. This latter type of integration is more difficult and less reported on than the former. Here, we present an outline of a course wherein the primary learning and teaching objective is to integrate basic science anatomy knowledge with clinical education. The course was developed through collaboration by a multi-specialist course development team (composed of both basic scientists and physicians) and was founded in current adult learning theories. The course was designed to be widely applicable to multiple future specialties, using current published reports regarding the topics and clinical care areas relying heavily on anatomical knowledge regardless of specialist focus. To this end, the course focuses on the role of anatomy in the diagnosis and treatment of frequently encountered musculoskeletal conditions. Our iterative implementation and action research approach to this course development has yielded a curricular template for anatomy integration into clinical years. Key components for successful implementation of these types of courses, including content topic sequence, the faculty development team, learning approaches, and hidden curricula, were developed. We also report preliminary feedback from course stakeholders and lessons learned through the process. The purpose of this report is to enhance the current literature regarding basic science integration in the clinical years of medical school. © 2014 American Association of Anatomists.

Posterior subscapular dissection: An improved approach to the brachial plexus for human anatomy students.

2014-05-01

Students of human anatomy are required to understand the brachial plexus, from the proximal roots extending from spinal nerves C5 through T1, to the distal-most branches that innervate the shoulder and upper limb. However, in human cadaver dissection labs, students are often instructed to dissect the brachial plexus using an antero-axillary approach that incompletely exposes the brachial plexus. This approach readily exposes the distal segments of the brachial plexus but exposure of proximal and posterior segments require extensive dissection of neck and shoulder structures. Therefore, the proximal and posterior segments of the brachial plexus, including the roots, trunks, divisions, posterior cord and proximally branching peripheral nerves often remain unobserved during study of the cadaveric shoulder and brachial plexus. Here we introduce a subscapular approach that exposes the entire brachial plexus, with minimal amount of dissection or destruction of surrounding structures. Lateral retraction of the scapula reveals the entire length of the brachial plexus in the subscapular space, exposing the brachial plexus roots and other proximal segments. Combining the subscapular approach with the traditional antero-axillary approach allows students to observe the cadaveric brachial plexus in its entirety. Exposure of the brachial dissection in the subscapular space requires little time and is easily incorporated into a preexisting anatomy lab curriculum without scheduling additional time for dissection.

Biomechanical Constraints Underlying Motor Primitives Derived from the Musculoskeletal Anatomy of the Human Arm.

Neural control of movement can only be realized though the interaction between the mechanical properties of the limb and the environment. Thus, a fundamental question is whether anatomy has evolved to simplify neural control by shaping these interactions in a beneficial way. This inductive data-driven study analyzed the patterns of muscle actions across multiple joints using the musculoskeletal model of the human upper limb. This model was used to calculate muscle lengths across the full range of motion of the arm and examined the correlations between these values between all pairs of muscles. Musculoskeletal coupling was quantified using hierarchical clustering analysis. Muscle lengths between multiple pairs of muscles across multiple postures were highly correlated. These correlations broadly formed two proximal and distal groups, where proximal muscles of the arm were correlated with each other and distal muscles of the arm and hand were correlated with each other, but not between groups. Using hierarchical clustering, between 11 and 14 reliable muscle groups were identified. This shows that musculoskeletal anatomy does indeed shape the mechanical interactions by grouping muscles into functional clusters that generally match the functional repertoire of the human arm. Together, these results support the idea that the structure of the musculoskeletal system is tuned to solve movement complexity problem by reducing the dimensionality of available solutions.

"Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy. © 2015 Elsevier B.V.

Animals are commonly used to model the human spine for in vitro and in vivo experiments. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae. However, a quantitative anatomic comparison of calf, pig, and human cervical spines has not been reported. To compare fundamental structural similarities and differences in vertebral bodies from the cervical spines of commonly used experimental animal models and humans. Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs). Multiple morphometric parameters were directly measured from cervical spine specimens of twelve pigs, twelve calves and twelve human adult cadavers. The following anatomical parameters were measured: vertebral body width (VBW), vertebral body depth (VBD), vertebral body height (VBH), spinal canal width (SCW), spinal canal depth (SCD), pedicle width (PW), pedicle depth (PD), pedicle inclination (PI), dens width (DW), dens depth (DD), total vertebral width (TVW), and total vertebral depth (TVD). The atlantoaxial (C1-2) joint in pigs is similar to that in humans and could serve as a human substitute. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4-C6. The width and depth of the calf odontoid process were larger than those in humans. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Calf C7 was relatively similar to human C7, thus, it may be a good substitute. Pig cervical vertebrae were more suitable human substitutions than calf cervical vertebrae, especially with respect to C1, C2, and C7. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

Our purpose in this study was to better understand the muscular anatomy of the ventricular folds in order to help improve biomechanical modeling of phonation and to better understand the role of these muscles during phonatory and nonphonatory tasks. Four human larynges were decalcified, sectioned coronally from posterior to anterior by a CryoJane tape transfer system, and stained with Masson's trichrome. The total and relative areas of muscles observed in each section were calculated and used for characterizing the muscle distribution within the ventricular folds. The ventricular folds contained anteriorly coursing thyroarytenoid and ventricularis muscle fibers that were in the lower half of the ventricular fold posteriorly, and some ventricularis muscle was evident in the upper and lateral portions of the fold more anteriorly. Very little muscle tissue was observed in the medial half of the fold, and the anterior half of the ventricular fold was largely devoid of any muscle tissue. All 4 larynges contained muscle bundles that coursed superiorly and medially through the upper half of the fold, toward the lateral margin of the epiglottis. Although variability of expression was evident, a well-defined thyroarytenoid muscle was readily apparent lateral to the arytenoid cartilage in all specimens.

Detailed Vascular Anatomy of the Human Retina by Projection-Resolved Optical Coherence Tomography Angiography

Optical coherence tomography angiography (OCTA) is a noninvasive method of 3D imaging of the retinal and choroidal circulations. However, vascular depth discrimination is limited by superficial vessels projecting flow signal artifact onto deeper layers. The projection-resolved (PR) OCTA algorithm improves depth resolution by removing projection artifact while retaining in-situ flow signal from real blood vessels in deeper layers. This novel technology allowed us to study the normal retinal vasculature in vivo with better depth resolution than previously possible. Our investigation in normal human volunteers revealed the presence of 2 to 4 distinct vascular plexuses in the retina, depending on location relative to the optic disc and fovea. The vascular pattern in these retinal plexuses and interconnecting layers are consistent with previous histologic studies. Based on these data, we propose an improved system of nomenclature and segmentation boundaries for detailed 3-dimensional retinal vascular anatomy by OCTA. This could serve as a basis for future investigation of both normal retinal anatomy, as well as vascular malformations, nonperfusion, and neovascularization.

Genomic validation of the differential preservation of population history in modern human cranial anatomy.

In modern humans, the significant correlation between neutral genetic loci and cranial anatomy suggests that the cranium preserves a population history signature. However, there is disagreement on whether certain parts of the cranium preserve this signature to a greater degree than other parts. It is also unclear how different quantitative measures of phenotype affect the association of genetic variation and anatomy. Here, we revisit these matters by testing the correlation of genetic distances and various phenotypic distances for ten modern human populations. Geometric morphometric shape data from the crania of adult individuals (n = 224) are used to calculate phenotypic P ST , Procrustes, and Mahalanobis distances. We calculate their correlation to neutral genetic distances, F ST , derived from single nucleotide polymorphisms (SNPs). We subset the cranial data into landmark configurations that include the neurocranium, the face, and the temporal bone in order to evaluate whether these cranial regions are differentially correlated to neutral genetic variation. Our results show that P ST , Mahalanobis, and Procrustes distances are correlated with F ST distances to varying degrees. They indicate that overall cranial shape is significantly correlated with neutral genetic variation. Of the component parts examined, P ST distances for both the temporal bone and the face have a stronger association with F ST distances than the neurocranium. When controlling for population divergence time, only the whole cranium and the temporal bone have a statistically significant association with F ST distances. Our results confirm that the cranium, as a whole, and the temporal bone can be used to reconstruct modern human population history. © 2016 Wiley Periodicals, Inc.

The study of anatomy in England during the 18th and 19th century has become infamous for bodysnatching from graveyards to provide a sufficient supply of cadavers. However, recent discoveries have improved our understanding of how and why anatomy was studied during the enlightenment, and allow us to see the context in which dissection of the human body took place. Excavations of infirmary burial grounds and medical school cemeteries, study of hospital archives, and analysis of the content of surviving anatomical collections in medical museums enables us to re-evaluate the field from a fresh perspective. The pathway from a death in poverty, sale of the corpse to body dealer, dissection by anatomist or medical student, and either the disposal and burial of the remains or preservation of teaching specimens that survive today in medical museums is a complex and fascinating one.

Abed Rabbo, F; Garrigues, F; Lefèvre, C; Seizeur, R

2016-03-01

Hours attributed to teaching anatomy have been reduced in medical curricula through out the world. In consequence, changes in anatomical curriculum as well as in teaching methods are becoming necessary. New methods of teaching are being evaluated. We present in the following paper an example of interactive anatomical teaching associating topographic anatomy with ultrasonographic radiological anatomy. The aim was to explicitly show anatomical structures of the knee and the ankle through dissection and ultrasonography. One cadaver was used as an ultrasonographic model and the other was dissected. Anatomy of the knee and ankle articulations was studied through dissection and ultrasonography. The students were able to simultaneously assimilate both anatomical aspects of radiological and topographic anatomy. They found the teaching very helpful and practical. This body of work provides example of a teaching method combining two important aspects of anatomy to help the students understand both aspects simultaneously. Copyright © 2015 Elsevier Masson SAS.

A new ontology (structured hierarchy) of human developmental anatomy for the first 7 weeks (Carnegie stages 1-20).

PubMed

Bard, Jonathan

2012-11-01

This paper describes a new ontology of human developmental anatomy covering the first 49 days [Carnegie stages (CS)1-20], primarily structured around the parts of organ systems and their development. The ontology includes more than 2000 anatomical entities (AEs) that range from the whole embryo, through organ systems and organ parts down to simple or leaf tissues (groups of cells with the same morphological phenotype), as well as features such as cavities. Each AE has assigned to it a set of facts of the form , with the relationships including starts_at and ends_at (CSs), part_of (there can be several parents) and is_a (this gives the type of tissue, from an organ system down to one of ~ 80 simple tissues predominantly composed of a single cell kind, which is also specified). Leaf tissues also have a develops_from link to its parent tissue. The ontology includes ~14 000 such facts, which are mainly from the literature and an earlier ontology of human developmental anatomy (EHDAA, now withdrawn). The relationships enable these facts to be integrated into a single, complex hierarchy (or mathematical graph) that was made and can be viewed in the OBO-Edit browser (oboedit.org). Each AE has an EHDAA2 ID that may be useful in an informatics context, while the ontology as a whole can be used for organizing databases of human development. It is also a knowledge resource: a user can trace the lineage of any tissue back to the egg, study the changes in cell phenotype that occur as a tissue develops, and use the structure to add further (e.g. molecular) information. The ontology may be downloaded from www.obofoundry.org. Queries and corrections should be sent to j.bard@ed.ac.uk. © 2012 The Author Journal of Anatomy © 2012 Anatomical Society.

On describing human white matter anatomy: the white matter query language.

2013-01-01

The main contribution of this work is the careful syntactical definition of major white matter tracts in the human brain based on a neuroanatomist's expert knowledge. We present a technique to formally describe white matter tracts and to automatically extract them from diffusion MRI data. The framework is based on a novel query language with a near-to-English textual syntax. This query language allows us to construct a dictionary of anatomical definitions describing white matter tracts. The definitions include adjacent gray and white matter regions, and rules for spatial relations. This enables automated coherent labeling of white matter anatomy across subjects. We use our method to encode anatomical knowledge in human white matter describing 10 association and 8 projection tracts per hemisphere and 7 commissural tracts. The technique is shown to be comparable in accuracy to manual labeling. We present results applying this framework to create a white matter atlas from 77 healthy subjects, and we use this atlas in a proof-of-concept study to detect tract changes specific to schizophrenia.

As technology advances, new and innovative ways of viewing and visualizing the human body are developed. Medicine has benefited greatly from imaging modalities that provide ways for us to visualize anatomy that cannot be seen without invasive procedures. As long as medical procedures include invasive operations, students of anatomy will benefit from the cadaveric dissection experience. Teaching proper technique for dissection of human cadavers is a challenging task for anatomy educators. Traditional methods, which have not changed significantly for centuries, include the use of textbooks and pictures to show students what a particular dissection specimen should look like. The ability to properly carry out such highly visual and interactive procedures is significantly constrained by these methods. The student receives a single view and has no idea how the procedure was carried out. The Department of Anatomy at Mayo Medical School recently built a new, state-of-the-art teaching laboratory, including data ports and power sources above each dissection table. This feature allows students to access the Mayo intranet from a computer mounted on each table. The vision of the Department of Anatomy is to replace all paper-based resources in the laboratory (dissection manuals, anatomic atlases, etc.) with a more dynamic medium that will direct students in dissection and in learning human anatomy. Part of that vision includes the use of interactive 3-D visualization technology. The Biomedical Imaging Resource (BIR) at Mayo Clinic has developed, in collaboration with the Department of Anatomy, a system for the control and capture of high resolution digital photographic sequences which can be used to create 3-D interactive visualizations of specimen dissections. The primary components of the system include a Kodak DC290 digital camera, a motorized controller rig from Kaidan, a PC, and custom software to synchronize and control the components. For each dissection procedure, the

We have developed a framework for the visual integration and exploration of multi-scale biomedical data, which includes anatomical and molecular components. We have also created a Java-based software system that integrates molecular information, such as gene expression data, into a three-dimensional digital atlas of the male adult human anatomy. Our atlas is structured according to the Terminologia Anatomica. The underlying data-indexing mechanism uses open standards and semantic ontology-processing tools to establish the associations between heterogeneous data types. The software system makes an extensive use of virtual reality visualization.

The field of anatomy, one of the most ancient sciences, first evolved in Egypt. From the Early Dynastic Period (3100 BC) until the time of Galen at the end of the 2nd century ad, Egypt was the center of anatomical knowledge, including neuroanatomy. Knowledge of neuroanatomy first became important so that sacred rituals could be performed by ancient Egyptian embalmers during mummification procedures. Later, neuroanatomy became a science to be studied by wise men at the ancient temple of Memphis. As religious conflicts developed, the study of the human body became restricted. Myths started to replace scientific research, squelching further exploration of the human body until Alexander the Great founded the city of Alexandria. This period witnessed a revolution in the study of anatomy and functional anatomy. Herophilus of Chalcedon, Erasistratus of Chios, Rufus of Ephesus, and Galen of Pergamon were prominent physicians who studied at the medical school of Alexandria and contributed greatly to knowledge about the anatomy of the skull base. After the Royal Library of Alexandria was burned and laws were passed prohibiting human dissections based on religious and cultural factors, knowledge of human skull base anatomy plateaued for almost 1500 years. In this article the authors consider the beginning of this journey, from the earliest descriptions of skull base anatomy to the establishment of basic skull base anatomy in ancient Egypt.

Evolutionary developmental pathology and anthropology: A new field linking development, comparative anatomy, human evolution, morphological variations and defects, and medicine.

2015-11-01

We introduce a new subfield of the recently created field of Evolutionary-Developmental-Anthropology (Evo-Devo-Anth): Evolutionary-Developmental-Pathology-and-Anthropology (Evo-Devo-P'Anth). This subfield combines experimental and developmental studies of nonhuman model organisms, biological anthropology, chordate comparative anatomy and evolution, and the study of normal and pathological human development. Instead of focusing on other organisms to try to better understand human development, evolution, anatomy, and pathology, it places humans as the central case study, i.e., as truly model organism themselves. We summarize the results of our recent Evo-Devo-P'Anth studies and discuss long-standing questions in each of the broader biological fields combined in this subfield, paying special attention to the links between: (1) Human anomalies and variations, nonpentadactyly, homeotic transformations, and "nearest neighbor" vs. "find and seek" muscle-skeleton associations in limb+facial muscles vs. other head muscles; (2) Developmental constraints, the notion of "phylotypic stage," internalism vs. externalism, and the "logic of monsters" vs. "lack of homeostasis" views about human birth defects; (3) Human evolution, reversions, atavisms, paedomorphosis, and peromorphosis; (4) Scala naturae, Haeckelian recapitulation, von Baer's laws, and parallelism between phylogeny and development, here formally defined as "Phylo-Devo parallelism"; and (5) Patau, Edwards, and Down syndrome (trisomies 13, 18, 21), atavisms, apoptosis, heart malformations, and medical implications. © 2015 Wiley Periodicals, Inc.

The history of anatomy in Persia.

PubMed

Shoja, Mohammadali M; Tubbs, R Shane

2007-04-01

The study of human anatomy can be found throughout the rich history of Persia. For thousands of years, morphological descriptions derived from this part of the world have contributed to and have helped form our current anatomical knowledge base. In this article we review the major influential Persian periods and the individuals who have contributed to the development of anatomy. We have divided the history of Persia into five eras: (1) the period of the Elamites, Medes, early Persians and Babylonians (10th millennium to 6th century BC); (2) following the establishment of the Persian Empire (6th century BC) to the 7th century AD; (3) after the Islamic conquest of Persia to the ascendency of Baghdad (7th to 13th century AD); (4) from the Mongol invasion of Persia to the foundations of modern anatomy (13th to 18th century AD); and (5) modern Persia/Iran (18th century AD to present). Evidence indicates that human dissection was commonplace in the first era, which led to a disciplined practice of surgery in the centuries leading to the foundation of the Persian Empire. By the emergence of Zoroastrianism in the Persian Empire, the microcosm theory was widely used to understand internal anatomy in relation to the external universe. The world's first cosmopolitan university and hospital were built in Gondishapur, south-western Persia, in the third century AD. Greek and Syriac knowledge influenced the second era. With the gradual ruin of Gondishapur and the foundation of Baghdad following the Islamic conquest of Persia (637-651 AD), a great movement took place, which led to the flourishing of the so-called Middle Age or Islamic Golden Age. Of the influential anatomists of this period, Mesue (777-857 AD), Tabbari (838-870 AD), Rhazes (865-925 AD), Joveini (?-983 AD), Ali ibn Abbas (930-994 AD), Avicenna (980-1037 AD) and Jorjani (1042-1137 AD) all hailed from Persia. There is evidence in the Persian literature as to the direct involvement of these scholars in human

Understanding the complexities of the liver has been a long-standing challenge to physicians and anatomists. Significant strides in the understanding of hepatic anatomy have facilitated major progress in liver-directed therapies--surgical interventions, such as transplantation, hepatic resection, hepatic artery infusion pumps, and hepatic ablation, and interventional radiologic procedures, such as transarterial chemoembolization, selective internal radiation therapy, and portal vein embolization. Without understanding hepatic anatomy, such progressive interventions would not be feasible.

It is essential for medical students to learn and comprehend human anatomy in three dimensions (3D). With this in mind, a new system was designed in order to integrate anatomical dissections with diagnostic computed tomography (CT) radiology. Cadavers were scanned by CT scanners, and students then consulted the postmortem CT images during cadaver dissection to gain a better understanding of 3D human anatomy and diagnostic radiology. Students used handheld digital imaging and communications in medicine viewers at the bench-side (OsiriX on iPod touch or iPad), which enabled "pixel-to-tissue" direct comparisons of CT images and cadavers. Students had lectures and workshops on diagnostic radiology, and they completed study assignments where they discussed findings in the anatomy laboratory compared with CT radiology findings. This teaching method for gross and radiological anatomy was used beginning in 2009, and it yielded strongly positive student perspectives and significant improvements in radiology skills in later clinical courses. © 2014 American Association of Anatomists.

Teaching anatomy by dissection is under considerable pressure to evolve and/or even be eliminated, and curricular hours in the dissection laboratory are decreasing. As a possible means of easing this pressure, an online interactive anatomy program has been created to enhance the dissection experience, observational learning, and three-dimensional comprehension of human anatomy. An assessment was made of the utility of the program in preparing students for dissection laboratories and for examinations. The efficacy of the application was evaluated by first-year students and faculty with pre- and post-use surveys in anatomy courses at three medical schools. It was found that students felt better prepared if they utilized the Web site prior to their dissection laboratory, and faculty reported spending less time explaining basic concepts or techniques. It is concluded that a comprehensive online program significantly enhances the quality and efficiency of instruction in human anatomy in the dissection laboratory and could prove to be a useful tool at other institutions.

A visual analysis of gender bias in contemporary anatomy textbooks.

PubMed

Parker, Rhiannon; Larkin, Theresa; Cockburn, Jon

2017-05-01

Empirical research has linked gender bias in medical education with negative attitudes and behaviors in healthcare providers. Yet it has been more than 20 years since research has considered the degree to which women and men are equally represented in anatomy textbooks. Furthermore, previous research has not explored beyond quantity of representation to also examine visual gender stereotypes and, in light of theoretical advancements in the area of intersectional research, the relationship between representations of gender and representations of ethnicity, body type, health, and age. This study aimed to determine the existence and representation of gender bias in the major anatomy textbooks used at Australian Medical Schools. A systematic visual content analysis was conducted on 6044 images in which sex/gender could be identified, sourced from 17 major anatomy textbooks published from 2008 to 2013. Further content analysis was performed on the 521 narrative images, which represent an unfolding story, found within the same textbooks. Results indicate that the representation of gender in images from anatomy textbooks remain predominantly male except within sex-specific sections. Further, other forms of bias were found to exist in: the visualization of stereotypical gendered emotions, roles and settings; the lack of ethnic, age, and body type diversity; and in the almost complete adherence to a sex/gender binary. Despite increased attention to gender issues in medicine, the visual representation of gender in medical curricula continues to be biased. The biased construction of gender in anatomy textbooks designed for medical education provides future healthcare providers with inadequate and unrealistic information about patients.

2012-07-01

In a problem-based learning curriculum, most medical students research the Internet for information for their "learning issues." Internet sites such as "YouTube" have become a useful resource for information. This study aimed at assessing YouTube videos covering surface anatomy. A search of YouTube was conducted from November 8 to 30, 2010 using research terms "surface anatomy," "anatomy body painting," "living anatomy," "bone landmarks," and "dermatomes" for surface anatomy-related videos. Only relevant video clips in the English language were identified and related URL recorded. For each videotape the following information were collected: title, authors, duration, number of viewers, posted comments, and total number of days on YouTube. The data were statistically analyzed and videos were grouped into educationally useful and non-useful videos on the basis of major and minor criteria covering technical, content, authority, and pedagogy parameters. A total of 235 YouTube videos were screened and 57 were found to have relevant information to surface anatomy. Analysis revealed that 15 (27%) of the videos provided useful information on surface anatomy. These videos scored (mean ± SD, 14.0 ± 0.7) and mainly covered surface anatomy of the shoulder, knee, muscles of the back, leg, and ankle, carotid artery, dermatomes, and anatomical positions. The other 42 (73%) videos were not useful educationally, scoring (mean ± SD, 7.4 ± 1.8). The total viewers of all videos were 1,058,634. Useful videos were viewed by 497,925 (47% of total viewers). The total viewership per day was 750 for useful videos and 652 for non-useful videos. No video clips covering surface anatomy of the head and neck, blood vessels and nerves of upper and lower limbs, chest and abdominal organs/structures were found. Currently, YouTube is an inadequate source of information for learning surface anatomy. More work is needed from medical schools and educators to add useful videos on You

On making nursing undergraduate human reproductive physiology content meaningful and relevant: discussion of human pleasure in its biological context.

PubMed

McClusky, Leon Mendel

2012-01-01

The traditional presentation of the Reproductive Physiology component in an Anatomy and Physiology course to nursing undergraduates focuses on the broad aspects of hormonal regulation of reproduction and gonadal anatomy, with the role of the higher centres of the brain omitted. An introductory discussion is proposed which could precede the lectures on the reproductive organs. The discussion gives an overview of the biological significance of human pleasure, the involvement of the neurotransmitter dopamine, and the role of pleasure in the survival of the individual and even species. Pleasure stimuli (positive and negative) and the biological significance of naturally-induced pleasurable experiences are briefly discussed in the context of reproduction and the preservation of genetic material with an aim to foster relevancy between subject material and human behaviour in any type of society. The tenderness of this aspect of the human existence is well-understood because of its invariable association with soul-revealing human expressions such as love, infatuation, sexual flirtations, all of which are underpinned by arousal, desire and/or pleasure. Assuming that increased knowledge correlates with increased confidence, the proposed approach may provide the nurse with an adequate knowledge base to overcome well-known barriers in communicating with their patients about matters of sexual health and intimacy.

In medicine, anatomy is considered as the most discussed field and results in a huge amount of knowledge, which is heterogeneous and covers aspects that are mostly independent in nature. Visual and symbolic modalities are mainly adopted for exemplifying knowledge about human anatomy and are crucial for the evolution of computational anatomy. In particular, a tight integration of visual and symbolic modalities is beneficial to support knowledge-driven methods for biomedical investigation. In this paper, we review previous work on the presentation and sharing of anatomical knowledge, and the development of advanced methods for computational anatomy, also focusing on the key research challenges for harmonizing symbolic knowledge and spatial 3D data.

Deep dissection: motivating students beyond rote learning in veterinary anatomy.

PubMed

Cake, Martin A

2006-01-01

The profusion of descriptive, factual information in veterinary anatomy inevitably creates pressure on students to employ surface learning approaches and "rote learning." This phenomenon may contribute to negative perceptions of the relevance of anatomy as a discipline. Thus, encouraging deep learning outcomes will not only lead to greater satisfaction for both instructors and learners but may have the added effect of raising the profile of and respect for the discipline. Consideration of the literature reveals the broad scope of interventions required to motivate students to go beyond rote learning. While many of these are common to all disciplines (e.g., promoting active learning, making higher-order goals explicit, reducing content in favor of concepts, aligning assessment with outcomes), other factors are peculiar to anatomy, such as the benefits of incorporating clinical tidbits, "living anatomy," the anatomy museum, and dissection classes into a "learning context" that fosters deep approaches. Surprisingly, the 10 interventions discussed focus more on factors contributing to student perceptions of the course than on drastic changes to the anatomy course itself. This is because many traditional anatomy practices, such as dissection and museum-based classes, are eminently compatible with active, student-centered learning strategies and the adoption of deep learning approaches by veterinary students. Thus the key to encouraging, for example, dissection for deep learning ("deep dissection") lies more in student motivation, personal engagement, curriculum structure, and "learning context" than in the nature of the learning activity itself.

Both in mainland China and around the world, regional anatomy stands as one of the most important basic science courses in medical school curricula. As such, dissection of human cadavers and use of prosected specimens remains the most essential teaching method in anatomy education. However, medical educators have raised increasing concerns about an ongoing shortage of cadavers for medical use in mainland China, a problem which may seriously limit the future development of human anatomy education. Based on a survey on cadaver usage in anatomy education in mainland China, this study found that the cadaver resources of most given medical schools in mainland China are associated with their geographic location, academic ranking, and local support for body donation policies. Effective measures to alleviate this shortage of cadavers may include future efforts to promote national-level body donation legislation, broader acceptance of body donation among Chinese citizens, and an efficient and humane protocol for body donation.

Properties of publications on anatomy in medical education literature.

Vorstenbosch, Marc; Bolhuis, Sanneke; van Kuppeveld, Sascha; Kooloos, Jan; Laan, Roland

2011-01-01

Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to "best evidence medical education" (BEME) and second to evaluate the development of this literature toward more "best evidence" between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words "anatomy," "anatomical," or "anatomist." Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about "teaching methods" and 17% about "teaching content," 8% referred to "practical value," and 10% to "side effects" of anatomy education. Ten percent of the statements were "positional," five percent "traditional," four percent "self-evident," and two percent referred to "quality of care." Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education. Copyright © 2011 American Association of Anatomists.

Are children competent producing anatomy cross-sections? To answer this question, we carried out a case study research aimed at testing graphic production skills in anatomy of nutrition. The graphics produced by 118 children in the final year of primary education were analysed. The children had to draw a diagram of a human cross section, integrating knowledge of anatomy acquired from longitudinal sections. The results show that they have very limited skills in producing these graphics judging by the dimensions (scale, shape, organs represented and its organization inside the section) and their conception of human anatomy at thoracic level (location of the organs, elements in the spaces between them and connections between organs). The results also indicate that the only exposure to cross-sections in daily life is not enough by itself to draw them correctly, so this type of graphic production should be addressed from the earliest stages of education, since it contributes to the development of visual literacy, and this is a crucial skill when it comes to learning science concepts and developing scientific literacy.

Constructing a biological model using an established ontology provides a unique opportunity to perform content auditing on the ontology. We built a Markov chain model to study tumor metastasis in the regional lymphatics of patients with head and neck squamous cell carcinoma (HNSCC). The model attempts to determine regions with high likelihood for metastasis, which guides surgeons and radiation oncologists in selecting the boundaries of treatment. To achieve consistent anatomical relationships, the nodes in our model are populated using lymphatic objects extracted from the Foundational Model of Anatomy (FMA) ontology. During this process, we discovered several classes of inconsistencies in the lymphatic representations within the FMA. We were able to use this model building opportunity to audit the entities and connections in this region of interest (ROI). We found five subclasses of errors that are computationally detectable and resolvable, one subclass of errors that is computationally detectable but unresolvable, requiring the assistance of a content expert, and also errors of content, which cannot be detected through computational means. Mathematical descriptions of detectable errors along with expert review were used to discover inconsistencies and suggest concepts for addition and removal. Out of 106 organ and organ parts in the ROI, 8 unique entities were affected, leading to the suggestion of 30 concepts for addition and 4 for removal. Out of 27 lymphatic chain instances, 23 were found to have errors, with a total of 32 concepts suggested for addition and 15 concepts for removal. These content corrections are necessary for the accurate functioning of the FMA and provide benefits for future research and educational uses.

The history of anatomy in Persia

The study of human anatomy can be found throughout the rich history of Persia. For thousands of years, morphological descriptions derived from this part of the world have contributed to and have helped form our current anatomical knowledge base. In this article we review the major influential Persian periods and the individuals who have contributed to the development of anatomy. We have divided the history of Persia into five eras: (1) the period of the Elamites, Medes, early Persians and Babylonians (10th millennium to 6th century BC); (2) following the establishment of the Persian Empire (6th century BC) to the 7th century AD; (3) after the Islamic conquest of Persia to the ascendency of Baghdad (7th to 13th century AD); (4) from the Mongol invasion of Persia to the foundations of modern anatomy (13th to 18th century AD); and (5) modern Persia/Iran (18th century AD to present). Evidence indicates that human dissection was commonplace in the first era, which led to a disciplined practice of surgery in the centuries leading to the foundation of the Persian Empire. By the emergence of Zoroastrianism in the Persian Empire, the microcosm theory was widely used to understand internal anatomy in relation to the external universe. The world's first cosmopolitan university and hospital were built in Gondishapur, south-western Persia, in the third century AD. Greek and Syriac knowledge influenced the second era. With the gradual ruin of Gondishapur and the foundation of Baghdad following the Islamic conquest of Persia (637–651 AD), a great movement took place, which led to the flourishing of the so-called Middle Age or Islamic Golden Age. Of the influential anatomists of this period, Mesue (777–857 AD), Tabbari (838–870 AD), Rhazes (865–925 AD), Joveini (?−983 AD), Ali ibn Abbas (930–994 AD), Avicenna (980–1037 AD) and Jorjani (1042–1137 AD) all hailed from Persia. There is evidence in the Persian literature as to the direct involvement of these scholars in

Ultrasound simulator-assisted teaching of cardiac anatomy to preclinical anatomy students: A pilot randomized trial of a three-hour learning exposure.

Ultrasound simulation allows students to virtually explore internal anatomy by producing accurate, moving, color, three-dimensional rendered slices from any angle or approach leaving the organs and their relationships intact without requirement for consumables. The aim was to determine the feasibility and efficacy of self-directed learning of cardiac anatomy with an ultrasound simulator compared to cadavers and plastic models. After a single cardiac anatomy lecture, fifty university anatomy students participated in a three-hour supervised self-directed learning exposure in groups of five, randomized to an ultrasound simulator or human cadaveric specimens and plastic models. Pre- and post-tests were conducted using pictorial and non-pictorial multiple-choice questions (MCQs). Simulator students completed a survey on their experience. Four simulator and seven cadaver group students did not attend after randomization. Simulator use in groups of five students was feasible and feedback from participants was very positive. Baseline test scores were similar (P = 0.9) between groups. After the learning intervention, there was no difference between groups in change in total test score (P = 0.37), whether they were pictorial (P = 0.6) or non-pictorial (P = 0.21). In both groups there was an increase in total test scores (simulator +19.8 ±12.4%% and cadaver: +16.4% ± 10.2, P < 0.0001), pictorial question scores (+22.9 ±18.0%, 19.7 ±19.3%, P < 0.001) and non-pictorial question scores (+16.7 ±18.2%, +13 ±15.4%, P = 0.002). The ultrasound simulator appears equivalent to human cadaveric prosections for learning cardiac anatomy. © 2014 American Association of Anatomists.

Human perception considerations for 3D content creation

Green, G. Almont

2011-03-01

Observation and interviews with people viewing autostereoscopic 3D imagery provides evidence that there are many human perception considerations required for 3D content creation. A study was undertaken whereby it was witnessed that certain test autostereoscopic imagery elicited a highly emotional response and engagement, while other test autostereoscopic imagery was given only a passing glance. That an image can be viewed with a certain level of stereopsis does not make it compelling. By taking into consideration the manner in which humans perceive depth and the space between objects, 3D content can achieve a level of familiarity and realness that is not possible with single perspective imagery. When human perception issues are ignored, 3D imagery can be undesirable to viewers and a negative bias against 3D imagery can occur. The preparation of 3D content is more important than the display technology. Where human perception, as it is used to interpret reality, is not mimicked in the creation of 3D content, the general public typically express a negative bias against that imagery (where choices are provided). For some, the viewing of 3D content that could not exist naturally, induces physical discomfort.

Drainage of the maxillary sinus: a comparative anatomy study in humans and goats.

Ford, Rebecca L; Barsam, Alon; Velusami, Prabhu; Ellis, Harold

2011-02-01

The maxillary sinuses are the most frequently infected paranasal sinuses in humans. It has been suggested that infection occurs relatively commonly in the maxillary sinuses owing to the position of their ostia high on their superomedial walls, which may be suboptimal for natural drainage. This may represent evolutionary lag, whereby the ostia remained in a quadrupedal position as bipedal humans evolved from their primate ancestors. This study examined the hypothesis that drainage of the maxillary sinus is optimal in the quadrupedal position. The drainage of the human maxillary sinus and an analogous quadruped, the goat, was examined and compared in the upright, quadrupedal, and intermediate positions. Department of Anatomy, King's College London. Cadaveric human and goat maxillary sinuses were filled with saline in each position and the volume at which saline overflowed through the ostia was noted. Volume at which spontaneous drainage occurred through ostia. The volume of saline instilled before drainage was maximal in the upright position and reduced with each increase in anterior tilt, with drainage occurring most easily at 90° for both human and goat sinuses. Drainage was significantly better in the quadrupedal head position than upright in both species (p < .01). This study demonstrated that human maxillary sinuses exhibit better passive drainage through their ostia when tilted anteriorly to mimic a quadrupedal head position. This may be an example of an evolutionary lag phenomenon and could be one etiologic factor in the prevalence of maxillary sinusitis in humans.

Hematological deficiencies increase with aging, including anemias, reduced responses to hematopoietic stress and myelodysplasias. This investigation tested the hypothesis that increased bone marrow (BM) fat content in humans with age was associated with decreased numbers of side population (SP) hematopoietic stem cells, and this decrease correlated with changes in cytokine levels. BM was obtained from the femoral head and trochanteric region of the femur removed at surgery for total hip replacement (N = 100 subjects). In addition, BM from cadavers (N = 36), with no evidence of hip disease, was evaluated for fat content. Whole trabecular marrow samples were ground in a sterile mortar and pestle, and cellularity and lipid content determined. Marrow cells were stained with Hoechst dye and SP profiles were acquired. Plasma levels of insulin-like growth factor (IGF)-1, stromal-derived factor (SDF)-1 and interleukin (IL)-6 were measured using ELISA. Fat content in the BM of human subjects and cadavers increased with age. The numbers of SP stem cells in BM as well as plasma IGF-1 and SDF-1 levels decreased in correlation with increased BM fat. IL-6 had no relationship to changes in marrow fat. These data suggest that increased BM fat may be associated with a decreased number of SP stem cells and IGF-1 and SDF-1 levels with aging. These data further raise a more general question as to the role of adipose cells in the regulation of tissue stem cells. © 2011 The Authors.

Petroclival meningiomas are a challenge for neurosurgeons due to the complex anatomy of the region that is rich of vessels and nerves. A perfect and detailed knowledge of the anatomy is very demanding in neurosurgery, especially in skull base surgery. The authors describe the microsurgical anatomy to perform an anterior petrosectomy based on their anatomical and surgical experience and perform a literature review. The temporal bone is the most complex and fascinating bone of skull base. The apex is located in the angle between the greater wing of the sphenoid and the occipital bone. Removing the petrous apex exposes the clivus. The approach directed through the temporal bone in this anatomical area is referred to as an anterior petrosectomy. The area that must be drilled is the rhomboid fossa that is defined by the Kawase, premeatal, and postmeatal triangles. In Division of Neurosurgery - University of Turin, 130 patients, from August 2013 to September 2015, underwent surgical resection of intracranial meningiomas. In this group, we have operated 7 PCMs and 5 of these were approached performing an anterior petrosectomy with good results. In our conclusions, we feel that this surgery require an advanced knowledge of human anatomy and a specialized training in interpretation of radiological and microsurgical anatomy both in the dissection lab and in the operating room.

Prevocational doctors aspiring to surgical careers are commonly recruited as anatomy demonstrators for undergraduate and graduate medical programmes. Entry into Surgical Education and Training (SET) is highly competitive and a unique opportunity exists to align anatomy demonstrator programmes with the selection criteria and core competencies of SET programmes. This study used a qualitative approach to (i) determine what criteria applicants for SET are assessed on and (ii) identify criteria that could be aligned with and enhanced by an anatomy demonstrator programme. The selection guidelines of all nine surgical specialties for the 2017 intake of SET trainees were analysed using qualitative content analysis methodology. The Royal Australasian College of Surgeons adopted a holistic approach to trainee selection that assessed both discipline-specific and discipline-independent skills. Qualitative content analysis identified eight categories of key selection criteria: medical expertise, scholarly activity, professional identity, interpersonal skills, integrity, self-management, insight and self-awareness and community involvement. The structured curriculum vitae was heavily weighted towards discipline-specific skills, such as medical expertise and scholarly activity. Insufficient information was available to determine the weighting of selection criteria assessed by the structured referee reports or interviews. Anatomy demonstrator programmes provide prevocational doctors with unique opportunities to develop surgical skills and competencies in a non-clinical setting. Constructively aligned anatomy demonstrator programmes may be particularly beneficial for prevocational doctors seeking to improve their anatomical knowledge, teaching skills or scholarly activity. © 2017 Royal Australasian College of Surgeons.

When confronted with the representation of human anatomy, natural language processing (NLP) system designers are facing an unsolved and frequent problem: the lack of a suitable global reference. The available sources in electronic format are numerous, but none fits adequately all the constraints and needs of language analysis. These sources are usually incomplete, difficult to use or tailored to specific needs. The anatomist's or ontologist's view does not necessarily match that of the linguist. The purpose of this paper is to review most recognized sources of knowledge in anatomy usable for linguistic analysis. Their potential and limits are emphasized according to this point of view. Focus is given on the role of the consensus work of the International Federation of Associations of Anatomists (IFAA) giving the Terminologia Anatomica. PMID:12463780

Active learning exercises were developed to allow advanced medical students to revisit and review anatomy in a clinically meaningful context. In our curriculum, students learn anatomy two to three years before they participate in the radiology clerkship. These educational exercises are designed to review anatomy content while highlighting its relevance to the study of radiology. Laboratory exercises were developed using inexpensive materials in the form of hands-on stations designed for use by students working together in small groups. Station exercises include model building, exploring relevant radiological imaging, and practicing clinical techniques. Students are encouraged to move from abstract conceptualization of the anatomy using models to applying knowledge to living tissues by using a portable ultrasound to explore superficial anatomy on each other. Stations are designed to integrate knowledge and reemphasize concepts in different contexts, so that upon completion students have a reinforced understanding of the three-dimensional anatomy of the region in question, the appearance of the anatomy on radiological images, and an appreciation of the relevance of the anatomy to radiological procedures.

Dermatologic problems of the face affect both function and aesthetics, which are based on complex anatomical features. Treating dermatologic problems while preserving the aesthetics and functions of the face requires knowledge of normal anatomy. When performing successfully invasive procedures of the face, it is essential to understand its underlying topographic anatomy. This chapter presents the anatomy of the facial musculature and neurovascular structures in a systematic way with some clinically important aspects. We describe the attachments of the mimetic and masticatory muscles and emphasize their functions and nerve supply. We highlight clinically relevant facial topographic anatomy by explaining the course and location of the sensory and motor nerves of the face and facial vasculature with their relations. Additionally, this chapter reviews the recent nomenclature of the branching pattern of the facial artery. © 2013 Elsevier Inc. All rights reserved.

Introductory anatomy and physiology in an undergraduate nursing curriculum.

Using an educational data mining approach, first-year academic achievement of undergraduate nursing students, which included two compulsory courses in introductory human anatomy and physiology, was compared with achievement in a final semester course that transitioned students into the workplace. We hypothesized that students could be grouped according to their first-year academic achievement using a two-step cluster analysis method and that grades achieved in the human anatomy and physiology courses would be strong predictors of overall achievement. One cohort that graduated in 2014 (n = 105) and one that graduated in 2015 (n = 94) were analyzed separately, and for both cohorts, two groups were identified, these being "high achievers" (HIGH) and "low achievers" (LOW). Consistently, the anatomy and physiology courses were the strongest predictors of group assignment, such that a good grade in these was much more likely to put a student into a high-achieving group. Students in the HIGH groups also scored higher in the Transition to Nursing course when compared with students in the LOW groups. The higher predictor importance of the anatomy and physiology courses suggested that if a first-year grade-point average was calculated for students, an increased weighting should be attributed to these courses. Identifying high-achieving students based on first-year academic scores may be a useful method to predict future academic performance. Copyright © 2017 the American Physiological Society.

The rat is the most used experimental model in surgical research. Virtually all procedures in clinical liver surgery can be performed in the rat. However, the use of the rat model in liver surgery is limited by its small size and limited knowledge of the liver anatomy. As in humans, the rat liver vasculature and biliary system have many anatomical variations. The development of surgical techniques, and the study of liver function and diseases require detailed knowledge of the regional anatomy. The objective of this study was to describe and illustrate systematically the surgical anatomy of the rat liver to facilitate the planning and performance of studies in this animal. Knowledge of the diameter and length of liver vessels is also important for the selection of catheters and perivascular devices. Twelve Wistar rat livers were dissected using a surgical microscope. Hepatic and extrahepatic anatomical structures were measured under magnification with a millimeter scale. In this study, we describe the rat liver topographical anatomy, compare it with the human liver and review the literature. Increased knowledge of the rat liver anatomy and microsurgical skills permit individualized dissection, parenchymal section, embolization and ligature of vascular and biliary branches.

The very word "anatomy" tells us about this branch's connection with dissection. Studies of anatomy have taken place for approximately 2.300 years already. Anatomy's birthplace lies in Greece and Egypt. Knowledge in this specific field of science was necessary during surgical procedures in ophthalmology and obstetrics. Embalming took place without public disapproval just like autopsies and manipulation with relics. Thus, anatomical dissection became part of later forensic sciences. Anatomical studies on humans themselves, which needed to be compared with the knowledge gained through studying procedures performed on animals, elicited public disapprobation and prohibition. When faced with a shortage of cadavers, anatomists resorted to obtaining bodies of the executed and suicide victims - since torture, public display of the mutilated body, (including anatomical autopsy), were perceived as an intensification of the death penalty. Decapitation and hanging were the main execution methods meted out for death sentences. Anatomists preferred intact bodies for dissection; hence, convicts could thus avoid torture. This paper lists examples of how this process was resolved. It concerns the manners of killing, vivisection on people in the antiquity and middle-ages, experiments before the execution and after, vivifying from seeming death, experiments with galvanizing electricity on fresh cadavers, evaluating of sensibility after guillotine execution, and making perfect anatomical preparations and publications during Nazism from fresh bodies of the executed.

Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was first to describe the maxillary sinus. PMID:24386595

The purpose of this study was to use the body painting method to teach hand anatomy to a group of preclinical medical students. Students reviewed hand anatomy using the traditional method and body painting exercise. Feedback and retention of the anatomy-related information were examined by a questionnaire and multiple-choice questions, respectively, immediately and 1 month after the painting exercise. Students agreed that the exercise was advantageous and helped facilitate self-active learning after in-class anatomy lessons. While there was no significant difference in knowledge retention between the control and experimental groups, the students appreciated the exercise in which they applied body paint to the human body to learn anatomy. The body painting was an efficient tool for aiding the interactive learning of medical students and increasing the understanding of gross anatomy.

Multimodal integration of anatomy and physiology classes: How instructors utilize multimodal teaching in their classrooms

NASA Astrophysics Data System (ADS)

McGraw, Gerald M., Jr.

Multimodality is the theory of communication as it applies to social and educational semiotics (making meaning through the use of multiple signs and symbols). The term multimodality describes a communication methodology that includes multiple textual, aural, and visual applications (modes) that are woven together to create what is referred to as an artifact. Multimodal teaching methodology attempts to create a deeper meaning to course content by activating the higher cognitive areas of the student's brain, creating a more sustained retention of the information (Murray, 2009). The introduction of multimodality educational methodologies as a means to more optimally engage students has been documented within educational literature. However, studies analyzing the distribution and penetration into basic sciences, more specifically anatomy and physiology, have not been forthcoming. This study used a quantitative survey design to determine the degree to which instructors integrated multimodality teaching practices into their course curricula. The instrument used for the study was designed by the researcher based on evidence found in the literature and sent to members of three associations/societies for anatomy and physiology instructors: the Human Anatomy and Physiology Society; the iTeach Anatomy & Physiology Collaborate; and the American Physiology Society. Respondents totaled 182 instructor members of two- and four-year, private and public higher learning colleges collected from the three organizations collectively with over 13,500 members in over 925 higher learning institutions nationwide. The study concluded that the expansion of multimodal methodologies into anatomy and physiology classrooms is at the beginning of the process and that there is ample opportunity for expansion. Instructors continue to use lecture as their primary means of interaction with students. Email is still the major form of out-of-class communication for full-time instructors. Instructors with

2002-01-01

Since the anatomy school of Alexandria during the fourth og third century before Christ dissection of the human body seems not to have been practiced until late Medieval or early Renaissance period, undoubtedly due to ethical and religious aversions. The teaching of anatomy was based on Galen using animal dissection. In the fourteenth and fifteenth centuries, however, anatomical examinations of the human body slowly began, seemingly for the purpose of describing both the normal structure and the abnormal structure caused by diseases, maldevelopment or trauma. This latter branch of anatomy was called practical, medical or correlative anatomy and corresponds to what we today name as patho-anatomy. Antonio Benivieni of Florence (1442-1502) is the first one to collect (and publish) a series of clinical observations some of which could be correlated to post mortem findings. It is unknown, however, whether the autopsies were performed by himself; and there is no mentioning of technique or circumstances for sectioning. Studies of the dead body by incision for the purpose of displaying diseased organs (autopsy) seem to have been an accepted practice for which relatives consented in those days. Other medical doctors in the years to follow, as for instance Fernel (1485-1558) in Paris, Eustachius (1524-1574) in Rome, Felix Plater (1536-1614) in Basle and Th. Bartholin (1616-1680) in Copenhagen have used the anatomical method for the study of diseases. Further, Schenck (1530-1598) in Freiburg and Bonet (1620-1689) in Genéva collected and published large series of clinical symptoms which had been related to post mortem findings dating back to ancient observers. This is the scientific background for anatomists as Morgagni, Lieutaud, Baillie, Bichât and others who founded the morbid anatomy on which the study of disease flourished in the classical patho-anatomical era of the nineteenth century with names as Rokitanski and Virchow.

Exploring Deep Space - Uncovering the Anatomy of Periventricular Structures to Reveal the Lateral Ventricles of the Human Brain.

Anatomy students are typically provided with two-dimensional (2D) sections and images when studying cerebral ventricular anatomy and students find this challenging. Because the ventricles are negative spaces located deep within the brain, the only way to understand their anatomy is by appreciating their boundaries formed by related structures. Looking at a 2D representation of these spaces, in any of the cardinal planes, will not enable visualisation of all of the structures that form the boundaries of the ventricles. Thus, using 2D sections alone requires students to compute their own mental image of the 3D ventricular spaces. The aim of this study was to develop a reproducible method for dissecting the human brain to create an educational resource to enhance student understanding of the intricate relationships between the ventricles and periventricular structures. To achieve this, we created a video resource that features a step-by-step guide using a fiber dissection method to reveal the lateral and third ventricles together with the closely related limbic system and basal ganglia structures. One of the advantages of this method is that it enables delineation of the white matter tracts that are difficult to distinguish using other dissection techniques. This video is accompanied by a written protocol that provides a systematic description of the process to aid in the reproduction of the brain dissection. This package offers a valuable anatomy teaching resource for educators and students alike. By following these instructions educators can create teaching resources and students can be guided to produce their own brain dissection as a hands-on practical activity. We recommend that this video guide be incorporated into neuroanatomy teaching to enhance student understanding of the morphology and clinical relevance of the ventricles.

Anatomy comic strips.

Comics are powerful visual messages that convey immediate visceral meaning in ways that conventional texts often cannot. This article's authors created comic strips to teach anatomy more interestingly and effectively. Four-frame comic strips were conceptualized from a set of anatomy-related humorous stories gathered from the authors' collective imagination. The comics were drawn on paper and then recreated with digital graphics software. More than 500 comic strips have been drawn and labeled in Korean language, and some of them have been translated into English. All comic strips can be viewed on the Department of Anatomy homepage at the Ajou University School of Medicine, Suwon, Republic of Korea. The comic strips were written and drawn by experienced anatomists, and responses from viewers have generally been favorable. These anatomy comic strips, designed to help students learn the complexities of anatomy in a straightforward and humorous way, are expected to be improved further by the authors and other interested anatomists.

2014-01-01

This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy-one first-year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post-test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions. © 2013 American Association of Anatomists.

Leonardo da Vinci (1452-1519) can be called one of the earliest contributors to the history of anatomy and, by extension, the study of medicine. He may have even overshadowed Andreas Vesalius (1514-1564), the so-called founder of human anatomy, if his works had been published within his lifetime. While some of the best illustrations of their time, with our modern knowledge of anatomy, it is clear that many of da Vinci's depictions of human anatomy are inaccurate. However, he also made significant discoveries in anatomy and remarkable predictions of facts he could not yet discover with the technology available to him. Additionally, da Vinci was largely influenced by Greek anatomists, as indicated from his ideas about anatomical structure. In this historical review, we describe da Vinci's history, influences, and discoveries in anatomical research and his depictions and errors with regards to the musculoskeletal system, cardiovascular system, nervous system, and other organs.

Background The purpose of this study was to use the body painting method to teach hand anatomy to a group of preclinical medical students. Methods Students reviewed hand anatomy using the traditional method and body painting exercise. Feedback and retention of the anatomy-related information were examined by a questionnaire and multiple-choice questions, respectively, immediately and 1 month after the painting exercise. Results Students agreed that the exercise was advantageous and helped facilitate self-active learning after in-class anatomy lessons. While there was no significant difference in knowledge retention between the control and experimental groups, the students appreciated the exercise in which they applied body paint to the human body to learn anatomy. Conclusion The body painting was an efficient tool for aiding the interactive learning of medical students and increasing the understanding of gross anatomy.

Medical schools revise their curricula in order to develop physicians best skilled to serve the public's needs. To ensure a smooth transition to residency programs, undergraduate medical education is often driven by the six core competencies endorsed by the Accreditation Council for Graduate Medical Education (ACGME): patient care, medical knowledge, practice-based learning, interpersonal skills, professionalism, and systems-based practice. Recent curricular redesign at Mayo Medical School provided an opportunity to restructure anatomy education and integrate radiology with first-year gross and developmental anatomy. The resulting 6-week (120-contact-hour) human structure block provides students with opportunities to learn gross anatomy through dissection, radiologic imaging, and embryologic correlation. We report more than 20 educational interventions from the human structure block that may serve as a model for incorporating the ACGME core competencies into basic science and early medical education. The block emphasizes clinically-oriented anatomy, invites self- and peer-evaluation, provides daily formative feedback through an audience response system, and employs team-based learning. The course includes didactic briefing sessions and roles for students as teachers, leaders, and collaborators. Third-year medical students serve as teaching assistants. With its clinical focus and competency-based design, the human structure block connects basic science with best-practice clinical medicine.

An anatomy precourse enhances student learning in veterinary anatomy.

2016-07-08

Veterinary anatomy is often a source of trepidation for many students. Currently professional veterinary programs, similar to medical curricula, within the United States have no admission requirements for anatomy as a prerequisite course. The purpose of the current study was to evaluate the impact of a week-long precourse in veterinary anatomy on both objective student performance and subjective student perceptions of the precourse educational methods. Incoming first year veterinary students in the Louisiana State University School of Veterinary Medicine professional curriculum were asked to participate in a free precourse before the start of the semester, covering the musculoskeletal structures of the canine thoracic limb. Students learned the material either via dissection only, instructor-led demonstrations only, or a combination of both techniques. Outcome measures included student performance on examinations throughout the first anatomy course of the professional curriculum as compared with those who did not participate in the precourse. This study found that those who participated in the precourse did significantly better on examinations within the professional anatomy course compared with those who did not participate. Notably, this significant improvement was also identified on the examination where both groups were exposed to the material for the first time together, indicating that exposure to a small portion of veterinary anatomy can impact learning of anatomical structures beyond the immediate scope of the material previously learned. Subjective data evaluation indicated that the precourse was well received and students preferred guided learning via demonstrations in addition to dissection as opposed to either method alone.

2017-12-28

To improve student preparedness for anatomy laboratory dissection, the dental gross anatomy laboratory was transformed using flipped classroom pedagogy. Instead of spending class time explaining the procedures and anatomical structures for each laboratory, students were provided online materials to prepare for laboratory on their own. Eliminating in-class preparation provided the opportunity to end each period with integrative group activities that connected laboratory and lecture material and explored clinical correlations. Materials provided for prelaboratory preparation included: custom-made, three-dimensional (3D) anatomy videos, abbreviated dissection instructions, key atlas figures, and dissection videos. Data from three years of the course (n = 241 students) allowed for analysis of students' preferences for these materials and detailed tracking of usage of 3D anatomy videos. Students reported spending an average of 27:22 (±17:56) minutes preparing for laboratory, similar to the 30 minutes previously allocated for in-class dissection preparation. The 3D anatomy videos and key atlas figures were rated the most helpful resources. Scores on laboratory examinations were compared for the three years before the curriculum change (2011-2013; n = 242) and three years after (2014-2016; n = 241). There was no change in average grades on the first and second laboratory examinations. However, on the final semi-cumulative laboratory examination, scores were significantly higher in the post-flip classes (P = 0.04). These results demonstrate an effective model for applying flipped classroom pedagogy to the gross anatomy laboratory and illustrate a meaningful role for 3D anatomy visualizations in a dissection-based course.

2016-10-01

Blended learning has become increasingly common, in a variety of disciplines, to take advantage of new technology and potentially increase the efficiency and flexibility of delivery. This study aimed to describe blended delivery of a gross anatomy course and to evaluate the effectiveness of the delivery in terms of student outcomes. A gross anatomy course for second-year physiotherapy students across two campuses was delivered in traditional face-to-face teaching mode in 2013 (n = 150 students), some online content was introduced in 2014 (n = 160) and the subject was fully blended in 2015 (n = 151). The final 'blend' consisted of one lecture per week with most content delivered using online video resources (prepared by staff using a structured peer-reviewed process) and retention of face-to-face practical classes. Outcomes evaluated included student grades, student engagement with content through online discussion forums and student feedback using both quantitative and qualitative analysis. Grades were higher in 2014 and 2015 than in 2013 (P < 0.01). There were no differences in student engagement with online discussion forums. Student feedback identified some negative comments and lower levels of intellectual stimulation (P < 0.05) with the initial introduction of online content in 2014. The fully blended version in 2015 resulted in more balanced comments about online content but higher perceived workload (P < 0.05). All cohorts listed practical classes as a major factor contributing to learning. Blended learning appears to be well-suited to gross anatomy teaching on the proviso that face-to-face practical classes are maintained, but may result in higher perceived workloads.

Tobii glasses can record corneal infrared light reflection to track pupil position and to map gaze focusing in the video recording. Eye tracking has been proposed for use in training and coaching as a visually guided control interface. The aim of our study was to test the potential use of these glasses in various situations: explanations of anatomical structures on tablet-type electronic devices, explanations of anatomical models and dissected cadavers, and during the prosection thereof. An additional aim of the study was to test the use of the glasses during laparoscopies performed on Thiel-embalmed cadavers (that allows pneumoinsufflation and exact reproduction of the laparoscopic surgical technique). The device was also tried out in actual surgery (both laparoscopy and open surgery). We performed a pilot study using the Tobii glasses. Dissection room at our School of Medicine and in the operating room at our Hospital. To evaluate usefulness, a survey was designed for use among students, instructors, and practicing physicians. The results were satisfactory, with the usefulness of this tool supported by more than 80% positive responses to most questions. There was no inconvenience for surgeons and that patient safety was ensured in the real laparoscopy. To our knowledge, this is the first publication to demonstrate the usefulness of eye tracking in practical instruction of human anatomy, as well as in teaching clinical anatomy and surgical techniques in the dissection and operating rooms.

The use of online social networks in medical education can remodel and enhance anatomy teaching and learning; one such network is the video-sharing site YouTube. Limited research in the literature exists on the use of YouTube as a platform for anatomy education. The aim of this study is to assess student's perceptions and patterns of usage of this resource, as well as the effectiveness of YouTube videos within a problem-based learning (PBL) curriculum. The study was conducted on 91 second-year medical students for whom video links were suggested throughout the academic year. In addition, the Human Anatomy Education (HAE) Channel was launched on YouTube to support classroom teaching with videos that emphasized applied aspects of anatomy. The results demonstrated that 98% of the students used YouTube as an online information resource, albeit in different frequencies. Out of the 86% who have been to the HAE Channel, 92% agreed/strongly agreed that the channel helped them learn anatomy. The study also reports the popularity of and awareness about using YouTube as a social network as well as in learning. Based on these findings, YouTube can be considered as an effective tool to enhance anatomy instruction if the videos are scrutinized, diversified, and aimed toward course objectives. Faculty of average computer literacy should be enabled to produce videos on their own YouTube channels to support independent learning and integration in a PBL curriculum. The methods described for capturing and editing the videos can be used as a prototype. Copyright © 2012 American Association of Anatomists.

Worldwide there is a growing reliance on sessional teachers in universities. This has impacted all disciplines in higher education including medical anatomy programs. The objective of this review was to define the role and support needs of sessional anatomy teachers by reporting on the (1) qualifications, (2) teaching role, (3) training, and (4) performance management of this group of educators. A systematic literature search was conducted on the 27 July 2017 in Scopus, Web of Science, and several databases on the Ovid, ProQuest and EBSCOhost platforms. The search retrieved 5,658 articles, with 39 deemed eligible for inclusion. The qualifications and educational distance between sessional anatomy teachers and their students varied widely. Reports of cross-level, near-peer and reciprocal-peer teaching were identified, with most institutes utilizing recent medical graduates or medical students as sessional teachers. Sessional anatomy teachers were engaged in the full spectrum of teaching-related duties from assisting students with cadaveric dissection, to marking student assessments and developing course materials. Fourteen institutes reported that training was provided to sessional anatomy teachers, but the specific content, objectives, methods and effectiveness of the training programs were rarely defined. Evaluations of sessional anatomy teacher performance primarily relied on subjective feedback measures such as student surveys (n = 18) or teacher self-assessment (n = 3). The results of this systematic review highlight the need for rigorous explorations of the use of sessional anatomy teachers in medical education, and the development of evidence-based policies and training programs that regulate and support the use of sessional teachers in higher education.

Is a Team-based Learning Approach to Anatomy Teaching Superior to Didactic Lecturing?

PubMed

Ghorbani, Naghme; Karbalay-Doust, Saied; Noorafshan, Ali

2014-02-01

Team-based learning (TBL) is used in the medical field to implement interactive learning in small groups. The learning of anatomy and its subsequent application requires the students to recall a great deal of factual content. The aims of this study were to evaluate the students' satisfaction, engagement and knowledge gain in anatomy through the medium of TBL in comparison to the traditional lecture method. This study, carried out from February to June 2012, included 30 physical therapy students of the Shiraz University of Medical Science, School of Rehabilitation Sciences. Classic TBL techniques were modified to cover lower limb anatomy topics in the first year of the physical therapy curriculum. Anatomy lectures were replaced with TBL, which required the preparation of assigned content, specific discussion topics, an individual self-assessment test (IRAT) and the analysis of discussion topics. The teams then subsequently retook the assessment test as a group (GRAT). The first eight weeks of the curriculum were taught using traditional didactic lecturing, while during the second eight weeks the modified TBL method was used. The students evaluated these sessions through a questionnaire. The impact of TBL on student engagement and educational achievement was determined using numerical data, including the IRAT, GRAT and final examination scores. Students had a higher satisfaction rate with the TBL teaching according to the Likert scale. Additionally, higher scores were obtained in the TBL-based final examination in comparison to the lecture-based midterm exam. The students' responses showed that the TBL technique could be used alone or in conjunction with traditional didactic lecturing in order to teach anatomy more effectively.

A fully online section of an existing face-to-face (F2F) systemic human anatomy course with a prosection laboratory was offered for the first time in 2012-2013. Lectures for F2F students (N = 365) were broadcast in both live and archived format to online students (N = 40) using virtual classroom software. Laboratories were delivered online by a teaching assistant who manipulated 3D computer models in the virtual classroom environment. An exploratory sequential mixed methods approach was undertaken to determine the most important deciding factors that drive students' preferences for a given format and then to generate theory on the strengths and weaknesses of the online format. Students (20 online; 310 F2F) volunteered to participate in a crossover period of one week to expose them to the course section in which they were not originally registered. Open ended interviews (20 online; 20 F2F) and quantitative surveys (270 F2F) were conducted following a crossover. Students valued pace control, schedule, and location flexibility of learning from archived materials and being assessed online. In the online laboratory they had difficulty using the 3D models and preferred the unique and hands-on experiences of cadaveric specimens. The F2F environment was conducive to learning in both lecture and laboratory because students felt more engaged by instructors in person and were less distracted by their surroundings. These results suggest the need to improve the online experience by increasing the quality of student-instructor communication and in turn student-content interaction with the 3D models.

The aim of this article is to systematically review the anatomy and action of the corrugator muscle. PubMed and Scopus were searched using the terms "corrugator" AND "anatomy." Among the 60 full texts from the 145 relevant abstracts, 34 articles without sufficient content were excluded and 4 articles drawn from the reference lists were added. Among the 30 articles analyzed (721 hemifaces), 28% classified by oblique head and transverse head, and 72% did not. Corrugator originated mostly from the medial supraorbital rim (45%), followed by the medial frontal bone (31%), the medial infraorbital rim (17%), and the upper nasal process (7%). Corrugator extended through the frontalis and orbicularis oculi (41%), only the frontalis (41%), or only the orbicularis oculi (18%). Corrugator ran superolaterally (59%), or laterally (41%). Corrugators inserted mostly to the middle of the eyebrow (57%), or the medial half of the eyebrow (36%), but also to the glabella region (7%). The length of the corrugator ranged 38 to 53 mm. The transverse head (23.38 mm) was longer than the oblique head (19.75 mm). Corrugator was thicker at the medial canthus than at the midpupillary line. Corrugator was innervated by the temporal branch of the facial nerve (66%), the zygomatic branch (17%), or the angular nerve (zygomatic branch and buccal branch, 17%). Supraorbital nerve (60%) or supratrochlear nerve (40%) penetrated the corrugator. The action was depressing, pulling the eyebrow medially (91%), or with medial eyebrow elevation and lateral eyebrow depression (9%). Surgeons must keep this anatomy in mind during surgical procedures.

We introduce a concept to model subtle part-whole-semantics for the use with interactive 3d-models of human anatomy. Similar to experiences with modeling partonomies for physical artifacts like machines or buildings we found one unique part-whole-relation to be insufficient to represent anatomical reality. This claim will be illustrated with anatomical examples. According to the requirements these examples demand, a semantic classification of part-whole-relations is introduced. Initial results in modeling anatomical partonomies for a 3d-visualization environment proved this approach to be an promising way to represent anatomy and to enable powerful complex inferences.

An Anatomy Pre-Course Predicts Student Performance in a Professional Veterinary Anatomy Curriculum.

PubMed

McNulty, Margaret A; Lazarus, Michelle D

2018-01-18

Little to no correlation has been identified between previous related undergraduate coursework or outcomes on standardized tests and performance in a veterinary curriculum, including anatomy coursework. Therefore, a relatively simplistic method to predict student performance before entrance would be advantageous to many. The purpose of this study was to evaluate whether there is a correlation between performance in a veterinary anatomy pre-course and subsequent performance within a professional anatomy curriculum. Incoming first-year veterinary students at the Louisiana State University School of Veterinary Medicine were asked to participate in a free weeklong pre-course, before the start of the semester. The pre-course covered the musculoskeletal anatomy of the canine thoracic limb using dissection-based methods. Student performance, as evaluated by test grades in the pre-course, did indeed correlate with test grades in professional veterinary anatomy courses. A significant and positive correlation was identified between pre-course final exam performance and performance on examinations in each of 3 professional anatomy courses. Qualitative analyses of student comments pertaining to their experience within the pre-course indicated differences in the perceived benefits of the pre-course between high-, middle-, and low-performing students. These varied perceptions may provide predictive feedback as well as guidance for supporting lower performing students. Together, these results indicate that performance in a weeklong pre-course covering only a small portion of canine anatomy is a strong predictor of performance within a professional anatomy curriculum. In addition, the pre-course differentially affected student perceptions of their learning experience.

Repeated Exposure to Dissection Does Not Influence Students' Attitudes towards Human Body Donation for Anatomy Teaching

The use of unclaimed bodies for anatomical dissection has been the main method of instruction at our institution. There is however a shortage of cadavers for dissection given the increase in the number of medical schools as well as in the number of students enrolling in these schools. This shortage could be mitigated by having voluntary human body donation programs. This study aimed at assessing the attitudes of medical students and surgical residents towards body donation for anatomy learning. We conducted an online survey involving 72 first-year medical students and 41 surgical residents at University of Nairobi who had completed one year of anatomy dissection. For the medical students, this was their first dissection experience while it was the second exposure for the surgery trainees. Most of the surgical trainees (70.7%) and medical students (68.1%) were opposed to self-body donation. This was mainly due to cultural (37%) and religious (20%) barriers. Surprisingly, of those not willing to donate themselves, 67.9% (82.8% surgical trainees, 59.2% medical students) would recommend the practice to other people. Exposure to repeated dissection does not change the perceptions towards body donation. It is noteworthy that culture and religion rank high as clear barriers amongst this “highly informed” group of potential donors. PMID:27190650

Anatomy has been at the foundation of medical students' training. In recent decades, medical programs in many countries have undergone major reform in both pedagogy and content. These reforms generated intense debates, focusing mainly on the way the new programs affected medical graduates' knowledge of anatomy and their clinical capabilities. Anatomy, however, is not only core to medicine, but also to a number of allied and complementary health disciplines. While the evaluation of anatomy teaching and learning in the medical programs has been heavily scrutinized, anatomy education in the complementary and alternative medicine (CAM) professions, including those, such as chiropractic, in which anatomy has traditionally been one of the main preclinical subjects, has been less frequently evaluated. The study aimed to make a preliminary assessment of the final year chiropractic students' knowledge of anatomy using the "carpal bone test." The testing was conducted on the final-year chiropractic students at Macquarie University in 2009. In this test, the students were given 5 minutes to label an illustration of the bony skeleton of the carpal region. The results of this assessment were then compared to results of previously published surveys using the "carpal bone test." A total of 84 students participated in the study. Thirty-eight percent (38%) of students identified all eight bones, while 60% of students identified five or more carpal bones. The most frequent correctly identified bone was the pisiform, followed by the scaphoid bone (82% and 74% of students, respectively). The trapezium and trapezoid bones were least frequently identified: both by 52% of students each. These results were generally better than those of the previously tested final-year medical students. The importance of anatomy in chiropractors' education has been generally acknowledged. This study suggests that the comparatively high number of hours devoted to anatomy in Macquarie University

The broad ligament is a double fold of peritoneum forming a mesentery for the human female genital tract. We investigated the anatomy of the broad ligament in different species and its hormonal regulation to determine if it had a role in gonadal positioning. The medical and veterinary literature was reviewed for descriptions of broad ligament anatomy and development. In addition, four adult female rats were dissected to compare the macroscopic anatomy of the broad ligament with any homologous structures in the male (n = 2). Detailed review was made of human males with persistent Müllerian duct syndrome (PMDS) and of bovine freemartin calves to determine the effect of abnormal hormonal environments on broad ligament development. Human and veterinary texts show variable broad ligament development between species, most being consistent with the size and shape of the uterus and uterine tubes. The broad ligament in adult female rats is a simple peritoneal fold and is homologous with the mesentery of the testis and vas deferens in males. Patients with PMDS and bovine freemartins have a broad ligament with intermediate anatomy. In PMDS the broad ligament is elongated and narrow, and not attached to the pelvic wall. The broad ligament is the mesentery of the genital ducts, and its anatomy varies with the degree of Müllerian duct fusion. The absence of a human male homologue is unusual, as the genital mesentery persists in male rodents. Apparent lack of a male homologue in the human may relate to obliteration of the processus vaginalis. The variable development of the broad ligament in pathological conditions is consistent with a role for steroid hormones in its development. Copyright 2004 Wiley-Liss, Inc.

A new wave of virtual reality headsets has become available. A potential benefit for the study of human anatomy is the reintroduction of stereopsis and absolute size. We report a randomized controlled trial to assess the contribution of stereopsis to anatomy learning, for students of different visuospatial ability. Sixty-three participants engaged in a one-hour session including a study phase and posttest. One group studied 3D models of the anatomy of the deep neck in full stereoptic virtual reality; one group studied those structures in virtual reality without stereoptic depth. The control group experienced an unrelated virtual reality environment. A post hoc questionnaire explored cognitive load and problem solving strategies of the participants. We found no effect of condition on learning. Visuospatial ability however did impact correct answers at F(1) = 5.63 and p = .02. No evidence was found for an impact of cognitive load on performance. Possibly, participants were able to solve the posttest items based on visuospatial information contained in the test items themselves. Additionally, the virtual anatomy may have been complex enough to discourage memory based strategies. It is important to control the amount of visuospatial information present in test items.

Purpose: The purpose of this study is to provide the first comprehensive description of gross anatomy course design in chiropractic colleges internationally and to provide baseline data for future investigation, future comparison with other health care professions, and identification of trends. Methods: A 72-question cross-sectional electronic survey was sent to the anatomy department chair at 36 chiropractic colleges internationally using Zoomerang, a web-based survey instrument. To augment the survey response data, public sources of data also were collected. Results: Forty-four percent of the electronic surveys were returned and information was gathered for 31 institutions from public sources. These results indicate (1) the most common degrees held by anatomy faculty were MS and PhD in anatomy, and DC degrees; (2) 75% of institutions utilized human cadavers and 75% presented laboratory anatomical demonstrations; (3) 62% used PowerPoint and 100% provided students with copies of lecture presentations; (4) 88% required attendance in laboratory and 50% in lecture; (5) 69% issued one grade for lecture and laboratory; (6) 100% of laboratory examinations were anatomical identification; and (7) 80% of written examinations were multiple-choice format. Conclusions: While individual variations existed, chiropractic institutions internationally have similar gross anatomy faculty, course design, delivery methods, and assessment methods. PMID:23362365

Radiological anatomy education is an important aspect of the medical curriculum. The purpose of this study was to establish and demonstrate the use of plastinated anatomical specimens, specifically human hearts, for use in radiological anatomy education. Four human hearts were processed with routine plastination procedures at room temperature. Specimens were subjected to cone beam computed tomography and a graphics program (ER3D) was applied to generate 3D cardiac models. A comparison was conducted between plastinated hearts and their corresponding computer models based on a list of morphological cardiac features commonly studied in the gross anatomy laboratory. Results showed significant correspondence between plastinations and CBCT-generated 3D models (98 %; p < .01) for external structures and 100 % for internal cardiac features, while 85 % correspondence was achieved between plastinations and 2D CBCT slices. Complete correspondence (100 %) was achieved between key observations on the plastinations and internal radiological findings typically required of medical student. All pathologic features seen on the plastinated hearts were also visualized internally with the CBCT-generated models and 2D slices. These results suggest that CBCT-derived slices and models can be successfully generated from plastinated material and provide accurate representations for radiological anatomy education.

This study was undertaken to develop a functional model of otitis media with effusion (OME) in the pig (Sus scrofa), with the purpose of investigating the origin of lymphocytes populating the middle ear during the course of an inflammatory process. The relevance of the model to the human condition of OME is to a large extent dependent on the anatomical and physiological similarities between the middle ear cavity and the pharyngeal lymphoid tissue of the pig and man. Anatomical specimens were collected from 7 young Large White pigs to determine the gross anatomy of the middle ear cavity and the histological characteristics of the middle ear mucosa. It was found that the anatomy of the 3 parts of the middle ear cavity in man and in the pig is broadly similar, although some minor differences were observed. The porcine eustachian tube was seen to be cartilaginous throughout its length in contrast to the part osseous, part cartilaginous structure found in man; the porcine ossicles were slightly different in shape to those of man and the air cell system was situated inferior to the tympanic cavity in the pig as opposed to posteriorly in man. This paper describes the structure and morphology of the pig middle ear cavity and compares and contrasts it with that of man. The minor differences observed are of anatomical importance but do not diminish the usefulness of the pig middle ear cleft as a potential model for human middle ear disorders. PMID:9688502

The study of human anatomy has traditionally served as a fundamental component in the basic science education of medical students, yet there exists a remarkable lack of firm guidance on essential features that must be included in a gross anatomy course, which would constitute a "Core Syllabus" of absolutely mandatory structures and related clinical pathologies. While universal agreement on the details of a core syllabus is elusive, there is a general consensus that a core syllabus aims to identify the minimum level of knowledge expected of recently qualified medical graduates in order to carry out clinical procedures safely and effectively, while avoiding overloading students with unnecessary facts that have less immediate application to their future careers as clinicians. This paper aims to identify consensus standards of essential features of Head and Neck anatomy via a Delphi Panel consisting of anatomists and clinicians who evaluated syllabus content structures (greater than 1,000) as "essential", "important", "acceptable", or "not required." The goal is to provide guidance for program/course directors who intend to provide the optimal balance between establishing a comprehensive list of clinically relevant essential structures and an overwhelming litany, which would otherwise overburden trainees in their initial years of medical school with superficial rote learning, which potentially dilutes the key and enduring fundamental lessons that prepare students for training in any medical field.

The Relationship between Muscle Fiber Type-Specific PGC-1α Content and Mitochondrial Content Varies between Rodent Models and Humans

PGC-1α regulates critical processes in muscle physiology, including mitochondrial biogenesis, lipid metabolism and angiogenesis. Furthermore, PGC-1α was suggested as an important regulator of fiber type determination. However, whether a muscle fiber type-specific PGC-1α content exists, whether PGC-1α content relates to basal levels of mitochondrial content, and whether such relationships are preserved between humans and classically used rodent models are all questions that have been either poorly addressed or never investigated. To address these issues, we investigated the fiber type-specific content of PGC-1α and its relationship to basal mitochondrial content in mouse, rat and human muscles using in situ immunolabeling and histochemical methods on muscle serial cross-sections. Whereas type IIa fibers exhibited the highest PGC-1α in all three species, other fiber types displayed a hierarchy of type IIx>I>IIb in mouse, type I = IIx> IIb in rat, and type IIx>I in human. In terms of mitochondrial content, we observed a hierarchy of IIa>IIx>I>IIb in mouse, IIa >I>IIx> IIb in rat, and I>IIa> IIx in human skeletal muscle. We also found in rat skeletal muscle that type I fibers displayed the highest capillarization followed by type IIa >IIx>IIb. Finally, we found in human skeletal muscle that type I fibers display the highest lipid content, followed by type IIa>IIx. Altogether, our results reveal that (i) the fiber type-specific PGC-1α and mitochondrial contents were only matched in mouse, (ii) the patterns of PGC-1α and mitochondrial contents observed in mice and rats do not correspond to that seen in humans in several respects, and (iii) the classical phenotypes thought to be regulated by PGC-1α do not vary exclusively as a function of PGC-1α content in rat and human muscles.

This study investigated the integration, implementation, and use of cadaver dissection, hospital radiology modalities, surgical tools, and AV technology during a 12-week contemporary anatomy course suggesting a millennial laboratory. The teaching of anatomy has undergone the greatest fluctuation of any of the basic sciences during the past 100 years in order to make room for the meteoric rise in molecular sciences. Classically, anatomy consisted of a 2-year methodical, horizontal, anatomy course; anatomy has now morphed into a 12-week accelerated course in a vertical curriculum, at most institutions. Surface and radiological anatomy is the language for all clinicians regardless of specialty. The objective of this study was to investigate whether integration of full-body dissection anatomy and modern hospital technology, during the anatomy laboratory, could be accomplished in a 12-week anatomy course. Literature search was conducted on anatomy text, journals, and websites regarding contemporary hospital technology integrating multiple image mediums of 37 embalmed cadavers, surgical suite tools and technology, and audio/visual technology. Surgical and radiology professionals were contracted to teach during the anatomy laboratory. Literature search revealed no contemporary studies integrating full-body dissection with hospital technology and behavior. About 37 cadavers were successfully imaged with roentograms, CT, and MRI scans. Students were in favor of the dynamic laboratory consisting of multiple activity sessions occurring simultaneously. Objectively, examination scores proved to be a positive outcome and, subjectively, feedback from students was overwhelmingly positive. Despite the surging molecular based sciences consuming much of the curricula, full-body dissection anatomy is irreplaceable regarding both surface and architectural, radiological anatomy. Radiology should not be a small adjunct to understand full-body dissection, but rather, full-body dissection

Gorilla-like anatomy on Australopithecus afarensis mandibles suggests Au. afarensis link to robust australopiths.

Mandibular ramus morphology on a recently discovered specimen of Australopithecus afarensis closely matches that of gorillas. This finding was unexpected given that chimpanzees are the closest living relatives of humans. Because modern humans, chimpanzees, orangutans, and many other primates share a ramal morphology that differs from that of gorillas, the gorilla anatomy must represent a unique condition, and its appearance in fossil hominins must represent an independently derived morphology. This particular morphology appears also in Australopithecus robustus. The presence of the morphology in both the latter and Au. afarensis and its absence in modern humans cast doubt on the role of Au. afarensis as a modern human ancestor. The ramal anatomy of the earlier Ardipithecus ramidus is virtually that of a chimpanzee, corroborating the proposed phylogenetic scenario.

Near-peer teaching is an educational format which utilizes tutors who are more advanced in a curriculum's content to supervise students' activities and to act as instructors in laboratory settings. This format is often used in anatomy laboratory courses. The goal of the present study is to describe the design and implementation of near-peer teaching in an anatomy course and to evaluate students' perceptions of the program. A total of 700 students were registered for this anatomy course which employed near-peer instructors. Of enrolled students, 558 (79.7%) agreed to participate in this study. In general, the practical section (e.g., the clinical hour, image-based anatomy session, and gross anatomy laboratory) of the course was viewed more favorably compared to the theory section (54.8%, n = 306), with dissection and prosection in the laboratory rated as the most valued experiences (34.9%, n = 195). Near-peer teaching is a viable option that satisfies the demands of modern curricula using small groups. This format stimulates learning within courses that have large numbers of students and low faculty-to-student ratios. Copyright © 2012 American Association of Anatomists.

From macro-scale to micro-scale computational anatomy: a perspective on the next 20 years.

PubMed

Mori, Kensaku

2016-10-01

This paper gives our perspective on the next two decades of computational anatomy, which has made great strides in the recognition and understanding of human anatomy from conventional clinical images. The results from this field are now used in a variety of medical applications, including quantitative analysis of organ shapes, interventional assistance, surgical navigation, and population analysis. Several anatomical models have also been used in computational anatomy, and these mainly target millimeter-scale shapes. For example, liver-shape models are almost completely modeled at the millimeter scale, and shape variations are described at such scales. Most clinical 3D scanning devices have had just under 1 or 0.5 mm per voxel resolution for over 25 years, and this resolution has not changed drastically in that time. Although Z-axis (head-to-tail direction) resolution has been drastically improved by the introduction of multi-detector CT scanning devices, in-plane resolutions have not changed very much either. When we look at human anatomy, we can see different anatomical structures at different scales. For example, pulmonary blood vessels and lung lobes can be observed in millimeter-scale images. If we take 10-µm-scale images of a lung specimen, the alveoli and bronchiole regions can be located in them. Most work in millimeter-scale computational anatomy has been done by the medical-image analysis community. In the next two decades, we encourage our community to focus on micro-scale computational anatomy. In this perspective paper, we briefly review the achievements of computational anatomy and its impacts on clinical applications; furthermore, we show several possibilities from the viewpoint of microscopic computational anatomy by discussing experimental results from our recent research activities.

Appreciating the contribution of donor-cadavers to medical education is a well observed practice among anatomists. However, the appreciation of their contribution in research and scientific articles remains dubious. We aimed to evaluate how much data anatomists provide about specimens they have used and how frequently anatomists acknowledge their cadavers in published articles. We evaluated all articles performed on human cadaveric specimens that were published in Clinical Anatomy and Surgical and Radiologic Anatomy between January 2011 and December 2015. We evaluated how much data on the demographics, preservation method(s), source, and ethical/legal permissions regarding cadavers were provided. We also evaluated the number of articles that acknowledged donor-cadavers. The majority of articles provided demographic data (age and sex) and preservation method used in the article. The source of the specimens was not mentioned in 45.6 % of the articles. Only 26.2 % of the articles provided a degree of consent and only 32.4 % of the articles reported some form of ethical approval for the study. The cadavers and their families were acknowledged in 17.7 % of the articles. We observed that no standard method for reporting data has been established. Anatomists should collaborate to create awareness among the scientific community for providing adequate information regarding donor-cadavers, including source and consent. Acknowledging donor-cadavers and/or their families should also be promoted. Scientific articles should be used to create a transparent relationship of trust between anatomists and their society.

Anatomy education often consists of a combination of lectures and laboratory sessions, the latter frequently including surface anatomy. Studying surface anatomy enables students to elaborate on their knowledge of the cadaver's static anatomy by enabling the visualization of structures, especially those of the musculoskeletal system, move and function in a living human being. A recent development in teaching methods for surface anatomy is body painting, which several studies suggest increases both student motivation and knowledge acquisition. This article focuses on a teaching approach and is a translational contribution to existing literature. In line with best evidence medical education, the aim of this article is twofold: to briefly inform teachers about constructivist learning theory and elaborate on the principles of constructive, collaborative, contextual, and self-directed learning; and to provide teachers with an example of how to implement these learning principles to change the approach to teaching surface anatomy. Student evaluations of this new approach demonstrate that the application of these learning principles leads to higher student satisfaction. However, research suggests that even better results could be achieved by further adjustments in the application of contextual and self-directed learning principles. Successful implementation and guidance of peer physical examination is crucial for the described approach, but research shows that other options, like using life models, seem to work equally well. Future research on surface anatomy should focus on increasing the students' ability to apply anatomical knowledge and defining the setting in which certain teaching methods and approaches have a positive effect.

The purpose of this study was to assess dental student learning in a dental anatomy module between traditional lecture and flipped classroom cohorts. Two cohorts of predoctoral dental students (N = 70 within each cohort) participated in a dental anatomy module within an Introduction to the Dental Patient (IDP) course ([traditional/lecture cohort: academic year (AY) 2012, 2013] and [flipped classroom cohort: AY 2014, 2015]). For the dental anatomy module, both cohorts were evaluated on pre-clinical tooth waxing exercises immediately after each of five lectures and tooth identification after all lectures were given. Additionally, the cohorts' performance on the overall IDP course examination was compared. The flipped classroom cohort had statistically significant higher waxing scores (dental anatomy module) than students in the traditional classroom. There was no statistically significant difference for tooth identification scores and the overall IDP course examination between the traditional vs flipped approach cohorts. This is due to the latter two assessments conducted at the end of the course gave all students enough time to review the lecture content prior to the assessment resulting in similar scores for both cohorts. The flipped classroom cohort promoted students' individual learning and resulted in improved students' performance on immediate evaluation but not on the end of the course evaluation. Redesign of courses to include a new pedagogical approach should be carefully implemented and evaluated for student's educational success. © 2017 John Wiley & Sons A/S.

Opinions differ regarding the scientific quality of the atlas by Govard Bidloo, Ontleding des Menschelijken Lichaams (Dissection of the Human Body) (1689) and the plagiarism made thereof by William Cowper, The Anatomy of Humane Bodies (1698). Both books were also published in Latin; the Society of the Dutch Journal of Medicine has acquired a copy of all 4 atlases. The anatomical plates were made by the artist Gerard de Lairesse (Liège 1640-Amsterdam 1711) and their great artistic value is beyond all doubt. De Lairesse settled in Amsterdam in 1665, a few months after the reopening of the city theatre, and subsequently achieved fame as an innovative creator of theatre sets. He also became one of the favourite artists of prince William III and many other well-to-do citizens of Amsterdam. The great artistic value of his anatomical plates justifies more attention for his importance as a medical illustrator in medical history.

Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages. © 2013 American Association of Anatomists.

Information security involves many branches of effort, including information assurance, host level security, physical security, and network security. Computer network security methods and implementations are given a top-down description to permit a medically focused audience to anchor this information to their daily practice. The depth of detail of network functionality and security measures, like that of the study of human anatomy, can be highly involved. Presented at the level of major gross anatomical systems, this paper will focus on network backbone implementation and perimeter defenses, then diagnostic tools, and finally the user practices (the human element).

The ramal anatomy of the earlier Ardipithecus ramidus is virtually that of a chimpanzee, corroborating the proposed phylogenetic scenario. PMID:17426152

Skull Base Anatomy.

2016-02-01

The anatomy of the skull base is complex with multiple neurovascular structures in a small space. Understanding all of the intricate relationships begins with understanding the anatomy of the sphenoid bone. The cavernous sinus contains the carotid artery and some of its branches; cranial nerves III, IV, VI, and V1; and transmits venous blood from multiple sources. The anterior skull base extends to the frontal sinus and is important to understand for sinus surgery and sinonasal malignancies. The clivus protects the brainstem and posterior cranial fossa. A thorough appreciation of the anatomy of these various areas allows for endoscopic endonasal approaches to the skull base. Copyright © 2016 Elsevier Inc. All rights reserved.

Anatomy and histology of the lower urinary tract.

2011-01-01

The function of the lower urinary tract is basically storage of urine in the bladder and the at-will periodic evacuation of the stored urine. Urinary incontinence is one of the most common lower urinary tract disorders in adults, but especially in the elderly female. The urethra, its sphincters, and the pelvic floor are key structures in the achievement of continence, but their basic anatomy is little known and, to some extent, still incompletely understood. Because questions with respect to continence arise from human morbidity, but are often investigated in rodent animal models, we present findings in human and rodent anatomy and histology. Differences between males and females in the role that the pelvic floor plays in the maintenance of continence are described. Furthermore, we briefly describe the embryologic origin of ureters, bladder, and urethra, because the developmental origin of structures such as the vesicoureteral junction, the bladder trigone, and the penile urethra are often invoked to explain (clinical) observations. As the human pelvic floor has acquired features in evolution that are typical for a species with bipedal movement, we also compare the pelvic floor of humans with that of rodents to better understand the rodent (or any other quadruped, for that matter) as an experimental model species. The general conclusion is that the "Bauplan" is well conserved, even though its common features are sometimes difficult to discern.

Glycogen provides an important glucose reservoir in the brain since the concentration of glucosyl units stored in glycogen is several fold higher than free glucose available in brain tissue. We have previously reported 3–4 µmol/g brain glycogen content using in vivo 13C magnetic resonance spectroscopy (MRS) in conjunction with [1-13C]glucose administration in healthy humans, while higher levels were reported in the rodent brain. Due to the slow turnover of bulk brain glycogen in humans, complete turnover of the glycogen pool, estimated to take 3–5 days, was not observed in these prior studies. In an attempt to reach complete turnover and thereby steady state 13C labeling in glycogen, here we administered [1-13C]glucose to healthy volunteers for 80 hours. To eliminate any net glycogen synthesis during this period and thereby achieve an accurate estimate of glycogen concentration, volunteers were maintained at euglycemic blood glucose levels during [1-13C]glucose administration and 13C-glycogen levels in the occipital lobe were measured by 13C MRS approximately every 12 hours. Finally, we fitted the data with a biophysical model that was recently developed to take into account the tiered structure of the glycogen molecule and additionally incorporated blood glucose levels and isotopic enrichments as input function in the model. We obtained excellent fits of the model to the 13C-glycogen data, and glycogen content in the healthy human brain tissue was found to be 7.8 ± 0.3 µmol/g, a value substantially higher than previous estimates of glycogen content in the human brain.

All eukaryotic cells utilize autophagy for protein and organelle turnover, thus assuring subcellular quality control, homeostasis, and survival. In order to address recent advances in identification of human autophagy associated genes, and to describe autophagy on a system-wide level, we established an autophagy-centered gene interaction network by merging various primary data sets and by retrieving respective interaction data. The resulting network (‘AXAN’) was analyzed with respect to subnetworks, e.g. the prime gene subnetwork (including the core machinery, signaling pathways and autophagy receptors) and the transcription subnetwork. To describe aspects of evolution within this network, we assessed the presence of protein orthologs across 99 eukaryotic model organisms. We visualized evolutionary trends for prime gene categories and evolutionary tracks for selected AXAN genes. This analysis confirms the eukaryotic origin of autophagy core genes while it points to a diverse evolutionary history of autophagy receptors. Next, we used module identification to describe the functional anatomy of the network at the level of pathway modules. In addition to obvious pathways (e.g., lysosomal degradation, insulin signaling) our data unveil the existence of context-related modules such as Rho GTPase signaling. Last, we used a tripartite, image-based RNAi – screen to test candidate genes predicted to play a role in regulation of autophagy. We verified the Rho GTPase, CDC42, as a novel regulator of autophagy-related signaling. This study emphasizes the applicability of system-wide approaches to gain novel insights into a complex biological process and to describe the human autophagy pathway at a hitherto unprecedented level of detail.

The patellofemoral joint, due to its particular bone anatomy and the numerous capsuloligamentous structures and muscles that act dynamically on the patella, is considered one of the most complex joints in the human body from the biomechanical point of view. The medial patellofemoral ligament (MPFL) has been demonstrated to contribute 60% of the force that opposes lateral displacement of the patella, and MPFL injury results in an approximately 50% reduction in the force needed to dislocate the patella laterally with the knee extended. For this reason, recent years have seen a growing interest in the study of this important anatomical structure, whose aponeurotic nature has thus been demonstrated. The MPFL acts as a restraint during motion, playing an active role under conditions of laterally applied stress, but an only marginal role during natural knee flexion. However, it remains extremely difficult to clearly define the anatomy of the MPFL and its relationships with other anatomical structures. PMID:25606512

The interest in the physical perfection and the corporal forms brings as a result the creation of new anatomical studies. The anatomical knowledge progressed in the second half of the XV century, conceiving the knowledge of the human body as a basic reality of Medicine. One of the greater contributions of the Italian Universities to medicine was the teaching of anatomy. The Universities of Padua, Bologna, and Pisa educated in their classrooms great physicians like Andres Vesalio, Gabriel Fallopio, Realdo Colombo, Mondino de Luzzi, Julio Ceasar Aranzio, and Gaspare Tagliacozzi, among others. The teaching of anatomy during the Renaissance was characterized by the development of dissection techniques and autopsy practice, which was recognized as an extremely valuable skill for anatomical study. The dissections were made in circular amphitheatres in the following way: a Medicine professor read the text book, another one made the dissection, and a third one indicated the structures referred.

Rejuvenative procedures of the face are increasing in numbers, and a plethora of different therapeutic options are available today. Every procedure should aim for the patient's safety first and then for natural and long-lasting results. The face is one of the most complex regions in the human body and research continuously reveals new insights into the complex interplay of the different participating structures. Bone, ligaments, muscles, fat, and skin are the key players in the layered arrangement of the face.Aging occurs in all involved facial structures but the onset and the speed of age-related changes differ between each specific structure, between each individual, and between different ethnic groups. Therefore, knowledge of age-related anatomy is crucial for a physician's work when trying to restore a youthful face.This review focuses on the current understanding of the anatomy of the human face and tries to elucidate the morphological changes during aging of bone, ligaments, muscles, and fat, and their role in rejuvenative procedures.

[Laurentius on anatomy].

PubMed

Sawai, Tadashi; Sakai, Tatsuo

2005-03-01

Andreas Laurentius wrote Opera anatomica (1593) and Historia anatomica (1600). These books were composed of two types of chapters; 'historia' and 'quaestio'. His description is not original, but take from other anatomists. 'Historia' describes the structure, action and usefulness of the body parts clarified after dissection. 'Quaestio' treats those questions which could not be solved only by dissection. Laurentius cited many previous contradicting interpretations to these questions and choose a best interpretation for the individual questions. In most cases, Laurentius preferred Galen's view. Historia anatomica retained almost all the 'historia' and 'quaestio' from Opera anatomica, and added some new 'historia' and 'quaestio', especially in regard to the components of the body, such as ligaments, membranes, vessels, nerves and glands. Other new 'historia' and 'quaestio' in Historia anatomica concerned several topics on anatomy in general to comprehensively analyze the history of anatomy, methods of anatomy, and usefulness of anatomy. Historia anatomica reviewed what was anatomy by describing in 'historia' what was known and in 'quaestio' what was unresolved. Till now Laurentius's anatomical works have attracted little attention because his description contained few original findings and depended on previous books. However, the important fact that Historia anatomica was very popular in the 17th century tells us that people needed non-original and handbook style of this textbook. Historia anatomica is important for further research on the propagation of anatomical knowledge from professional anatomists to non-professionals in the 17th century.

2014-09-01

The porcine model has contributed significantly to biomedical research over many decades. The similar size and anatomy of pig and human organs make this model particularly beneficial for translational research in areas such as medical device development, therapeutics and xenotransplantation. In recent years, a major limitation with the porcine model was overcome with the successful generation of gene-targeted pigs and the publication of the pig genome. As a result, the role of this model is likely to become even more important. For the respiratory medicine field, the similarities between pig and human lungs give the porcine model particular potential for advancing translational medicine. An increasing number of lung conditions are being studied and modeled in the pig. Genetically modified porcine models of cystic fibrosis have been generated that, unlike mouse models, develop lung disease similar to human cystic fibrosis. However, the scientific literature relating specifically to porcine lung anatomy and airway histology is limited and is largely restricted to veterinary literature and textbooks. Furthermore, methods for in vivo lung procedures in the pig are rarely described. The aims of this review are to collate the disparate literature on porcine lung anatomy, histology, and microbiology; to provide a comparison with the human lung; and to describe appropriate bronchoscopy procedures for the pig lungs to aid clinical researchers working in the area of translational respiratory medicine using the porcine model.

Little is known about the effect of advanced maternal age upon macronutrients of human milk. This study was designed to study contents of macronutrients (fat, lactose, and protein) in human milk collected in the first 2 weeks of life in older (≥35 years) compared with younger (<35 years) mothers. Seventy-two lactating mothers (38 older, 34 younger) of newborns were recruited within the first 3 days of delivery. Macronutrient contents were measured at 72 hours, 7 days, and 14 days after delivery using infrared transmission spectroscopy. The groups did not differ in terms of maternal prepregnancy weight, height, and diet or infant birth weight or gestational age. They differed significantly in terms of maternal age and maternal weight after pregnancy. Fat content in colostrum and carbohydrate content in mature milk were significantly higher in the older mothers group. Moreover, carbohydrates in mature milk correlated positively with maternal age. Fat content at an infant age of 7 days and 2 weeks was not affected by maternal age. There was no significant relationship between maternal body weight for height (or body mass index) and energy, protein, fat or lactose content at any stage. Fat content of colostrum and carbohydrate content of mature milk obtained from mothers with advanced age are elevated compared with those of younger mothers. Moreover, there is a positive correlation between maternal age and carbohydrate content in mature milk. The biological significance of our findings is yet to be determined.

Nearly eleven years have passed since the International Agency for Research on Cancer classified Formaldehyde (FA) as a known human carcinogen (group 1), yet the safety of anatomy pathology workers who are currently exposed to FA is still a matter of concern. The purpose of this study was to evaluate the literature to discover which topics have been focused on and what the latest developments are in managing FA indoor pollution in anatomy pathology departments. which topics have been focused on and what the latest developments in managing FA indoor pollution in anatomy pathology departments. For the purpose of this review, we searched for publications in PubMed and Web of Science using selected keywords. The articles were reviewed and categorized into one or more of the following three categories based on subject matter: exposure levels exposure controls and alternatives. Our search resulted in a total of 31 publications that matched our inclusion criteria. The topics discussed, in order of frequency (from highest to lowest), were: "exposure controls", "exposure levels" and "alternatives". The most frequently suggested intervention was to improve local exhaust ventilation systems to minimize FA levels in gross anatomy laboratories. We found a lack of evidence-based improvement interventions that aimed to control exposure to FA. According to this finding, and pending a valid chemical substitute for FA, we suggest the need for more in-depth studies targeting measures to minimize exposures to FA in pathology departments.

Knowledge of skull base anatomy and surgical implications of human sacrifice among pre-Columbian Mesoamerican cultures.

Human sacrifice became a common cultural trait during the advanced phases of Mesoamerican civilizations. This phenomenon, influenced by complex religious beliefs, included several practices such as decapitation, cranial deformation, and the use of human cranial bones for skull mask manufacturing. Archaeological evidence suggests that all of these practices required specialized knowledge of skull base and upper cervical anatomy. The authors conducted a systematic search for information on skull base anatomical and surgical knowledge among Mesoamerican civilizations. A detailed exposition of these results is presented, along with some interesting information extracted from historical documents and pictorial codices to provide a better understanding of skull base surgical practices among these cultures. Paleoforensic evidence from the Great Temple of Tenochtitlan indicates that Aztec priests used a specialized decapitation technique, based on a deep anatomical knowledge. Trophy skulls were submitted through a stepwise technique for skull mask fabrication, based on skull base anatomical landmarks. Understanding pre-Columbian Mesoamerican religions can only be realized by considering them in their own time and according to their own perspective. Several contributions to medical practice might have arisen from anatomical knowledge emerging from human sacrifice and decapitation techniques.

Anatomical education is becoming modernized, not only in its teaching and learning, but also in its assessment formats. Traditional "steeplechase" examinations are being replaced with online gross anatomy examinations. The aims of this study were to: (1) determine if online anatomy practical examinations are equivalent to traditional anatomy practical examinations; and (2) to examine if students' perceptions of the online or laboratory testing environments influenced their performance on the examinations. In phase one, 10 third-year students were interviewed to generate perception items to which five anatomy lecturers assigned content validity. In phase two, students' gross anatomical knowledge was assessed by examinations in two modes and their perceptions were examined using the devised survey instrument. Forty-five second-year chiropractic students voluntarily participated in Phase Two. The two randomly allocated groups completed the examinations in a sequential cross-over manner. Student performance on the gross anatomy examination was not different between traditional "steeplechase" (mean ± standard deviation (SD): 69 ± 11%) and online (68 ± 15%) modes. The majority of students (87%) agreed that they felt comfortable using computers for gross anatomy examinations. However, fewer students found it easy to orientate images of cadaver specimens online. The majority of students (85%) agreed that they felt comfortable working with cadavers but there was less agreement on the effect of moving around the laboratory during practical examinations. This data will allow anatomists to confidently implement online assessments without fear of jeopardizing academic rigor or student performance. © 2015 American Association of Anatomists.

Felix Vicq d'Azyr: anatomy, medicine and revolution.

Parent, André

2007-02-01

Félix Vicq d'Azyr was born in 1748 in the small town of Valognes, Normandy. He studied medicine in Paris but he was particularly impressed by the lectures given at the Jardin du Roi by the comparative anatomist Louis Daubenton and the surgeon Antoine Petit. In 1773, Vicq d'Azyr initiated a series of successful lectures on human and animal anatomy at the Paris Medical School, from which he received his medical degree in 1774. He was elected the same year at the Academy of Sciences at age 26, thanks to his outstanding contributions to comparative anatomy. Vicq d'Azyr became widely known after his successful management of a severe cattle plague that occurred in the southern part of France in 1774, an event that led to the foundation of the Royal Society of Medicine in 1778. As Permanent Secretary of this society, Vicq d'Azyr wrote several eulogies that were models of eloquence and erudition and worth him a seat at the French Academy in 1788. Vicq d'Azyr published in 1786 a remarkable anatomy and physiology treatise: a large in-folio that contained original descriptions illustrated by means of nature-sized, colored, human brain figures of a quality and exactitude never attained before. In 1789, Vicq d'Azyr was appointed physician to the Queen Marie-Antoinette and, in 1790, he presented to the Constituent Assembly a decisive plan to reform the teaching of medicine in France. Unfortunately, Vicq d'Azyr did not survive the turmoil of the French Revolution; he died at age 46 on June 20, 1794.

Student perceptions about learning anatomy

NASA Astrophysics Data System (ADS)

Notebaert, Andrew John

This research study was conducted to examine student perceptions about learning anatomy and to explore how these perceptions shape the learning experience. This study utilized a mixed-methods design in order to better understand how students approach learning anatomy. Two sets of data were collected at two time periods; one at the beginning and one at the end of the academic semester. Data consisted of results from a survey instrument that contained open-ended questions and a questionnaire and individual student interviews. The questionnaire scored students on a surface approach to learning (relying on rote memorization and knowing factual information) scale and a deep approach to learning (understanding concepts and deeper meaning behind the material) scale. Students were asked to volunteer from four different anatomy classes; two entry-level undergraduate courses from two different departments, an upper-level undergraduate course, and a graduate level course. Results indicate that students perceive that they will learn anatomy through memorization regardless of the level of class being taken. This is generally supported by the learning environment and thus students leave the classroom believing that anatomy is about memorizing structures and remembering anatomical terminology. When comparing this class experience to other academic classes, many students believed that anatomy was more reliant on memorization techniques for learning although many indicated that memorization is their primary learning method for most courses. Results from the questionnaire indicate that most students had decreases in both their deep approach and surface approach scores with the exception of students that had no previous anatomy experience. These students had an average increase in surface approach and so relied more on memorization and repetition for learning. The implication of these results is that the learning environment may actually amplify students' perceptions of the anatomy

The “Ice Age” of Anatomy and Obstetrics:

PubMed Central

Al-Gailani, Salim

2016-01-01

summary In the late nineteenth century anatomists claimed a new technique—slicing frozen corpses into sections—translated the three-dimensional complexity of the human body into flat, visually striking, and unprecedentedly accurate images. Traditionally hostile to visual aids, elite anatomists controversially claimed frozen sections had replaced dissection as the “true anatomy.” Some obstetricians adopted frozen sectioning to challenge anatomists’ authority and reform how clinicians made and used pictures. To explain the successes and failures of the technique, this article reconstructs the debates through which practitioners learned to make and interpret, to promote or denigrate frozen sections in teaching and research. Focusing on Britain, the author shows that attempts to introduce frozen sectioning into anatomy and obstetrics shaped and were shaped by negotiations over the epistemological standing of hand and eye in medicine.

Kish, Gary; Cook, Samuel A; Kis, Gréta

2013-01-01

The University of Debrecen's Faculty of Medicine has an international, multilingual student population with anatomy courses taught in English to all but Hungarian students. An elective computer-assisted gross anatomy course, the Computer Human Anatomy (CHA), has been taught in English at the Anatomy Department since 2008. This course focuses on an introduction to anatomical digital images along with clinical cases. This low-budget course has a large visual component using images from magnetic resonance imaging and computer axial tomogram scans, ultrasound clinical studies, and readily available anatomy software that presents topics which run in parallel to the university's core anatomy curriculum. From the combined computer images and CHA lecture information, students are asked to solve computer-based clinical anatomy problems in the CHA computer laboratory. A statistical comparison was undertaken of core anatomy oral examination performances of English program first-year medical students who took the elective CHA course and those who did not in the three academic years 2007-2008, 2008-2009, and 2009-2010. The results of this study indicate that the CHA-enrolled students improved their performance on required anatomy core curriculum oral examinations (P < 0.001), suggesting that computer-assisted learning may play an active role in anatomy curriculum improvement. These preliminary results have prompted ongoing evaluation of what specific aspects of CHA are valuable and which students benefit from computer-assisted learning in a multilingual and diverse cultural environment.

A new ontology (structured hierarchy) of human developmental anatomy for the first 7 weeks (Carnegie stages 1–20)

Bard, Jonathan

2012-01-01

This paper describes a new ontology of human developmental anatomy covering the first 49 days [Carnegie stages (CS)1–20], primarily structured around the parts of organ systems and their development. The ontology includes more than 2000 anatomical entities (AEs) that range from the whole embryo, through organ systems and organ parts down to simple or leaf tissues (groups of cells with the same morphological phenotype), as well as features such as cavities. Each AE has assigned to it a set of facts of the form , with the relationships including starts_at and ends_at (CSs), part_of (there can be several parents) and is_a (this gives the type of tissue, from an organ system down to one of ∼ 80 simple tissues predominantly composed of a single cell kind, which is also specified). Leaf tissues also have a develops_from link to its parent tissue. The ontology includes ∼14 000 such facts, which are mainly from the literature and an earlier ontology of human developmental anatomy (EHDAA, now withdrawn). The relationships enable these facts to be integrated into a single, complex hierarchy (or mathematical graph) that was made and can be viewed in the OBO-Edit browser (http://oboedit.org). Each AE has an EHDAA2 ID that may be useful in an informatics context, while the ontology as a whole can be used for organizing databases of human development. It is also a knowledge resource: a user can trace the lineage of any tissue back to the egg, study the changes in cell phenotype that occur as a tissue develops, and use the structure to add further (e.g. molecular) information. The ontology may be downloaded from http://www.obofoundry.org. Queries and corrections should be sent to j.bard@ed.ac.uk. PMID:22973865

FASH and MASH: female and male adult human phantoms based on polygon mesh surfaces: I. Development of the anatomy

Among computational models, voxel phantoms based on computer tomographic (CT), nuclear magnetic resonance (NMR) or colour photographic images of patients, volunteers or cadavers have become popular in recent years. Although being true to nature representations of scanned individuals, voxel phantoms have limitations, especially when walled organs have to be segmented or when volumes of organs or body tissues, like adipose, have to be changed. Additionally, the scanning of patients or volunteers is usually made in supine position, which causes a shift of internal organs towards the ribcage, a compression of the lungs and a reduction of the sagittal diameter especially in the abdominal region compared to the regular anatomy of a person in the upright position, which in turn can influence organ and tissue absorbed or equivalent dose estimates. This study applies tools developed recently in the areas of computer graphics and animated films to the creation and modelling of 3D human organs, tissues, skeletons and bodies based on polygon mesh surfaces. Female and male adult human phantoms, called FASH (Female Adult meSH) and MASH (Male Adult meSH), have been designed using software, such as MakeHuman, Blender, Binvox and ImageJ, based on anatomical atlases, observing at the same time organ masses recommended by the International Commission on Radiological Protection for the male and female reference adult in report no 89. 113 organs, bones and tissues have been modelled in the FASH and the MASH phantoms representing locations for adults in standing posture. Most organ and tissue masses of the voxelized versions agree with corresponding data from ICRP89 within a margin of 2.6%. Comparison with the mesh-based male RPI_AM and female RPI_AF phantoms shows differences with respect to the material used, to the software and concepts applied, and to the anatomies created.

Ultrasound (US) can enhance anatomy education, yet is incorporated into few non-medical anatomy programs. This study is the first to evaluate the impact of US training in gross anatomy for non-medical students in the United States. All 32 master's students enrolled in gross anatomy with the anatomy-centered ultrasound (ACUS) curriculum were recruited. Mean Likert ratings on pre- and post-course surveys (100% response rates) were compared to evaluate the effectiveness of the ACUS curriculum in developing US confidence, and gauge its impact on views of US. Post-course, students reported significantly higher (P < 0.001) mean confidence ratings in five US skills (pre-course versus post-course mean): obtaining scans (3.13 ±1.04 versus 4.03 ±0.78), optimizing images (2.78 ±1.07 versus 3.75 ±0.92), recognizing artifacts (2.94 ±0.95 versus 3.97 ±0.69), distinguishing tissue types (2.88 ±0.98 versus 4.09 ±0.69), and identifying structures (2.97 ±0.86 versus 4.03 ±0.59), demonstrating the success of the ACUS curriculum in students with limited prior experience. Views on the value of US to anatomy education and to students' future careers remained positive after the course. End-of-semester quiz performance (91% response rate) provided data on educational outcomes. The average score was 79%, with a 90% average on questions about distinguishing tissues/artifacts, demonstrating positive learning outcomes and retention. The anatomy-centered ultrasound curriculum significantly increased confidence with and knowledge of US among non-medical anatomy students with limited prior training. Non-medical students greatly value the contributions that US makes to anatomy education and to their future careers. It is feasible to enhance anatomy education outside of medical training by incorporating US.

The purpose of this study was to investigate whether learning thinking strategies within the context of a community college course in Human Anatomy and Physiology would result in increased academic performance and the incidence of critical thinking skills. Included in the study sample were 68 community college students, many of whom would be categorized as "at-risk," who were enrolled in four sections of a Human Anatomy and Physiology class. Two of the class sections served as the experimental group and two sections served as the control group. During the course of one semester, members of the experimental group participated in the use of a student-generated questioning technique in conjunction with lecture presentations, while members of the control group did not. All students were pretested using the Learning and Study Strategies Inventory (LASSI) and the California Critical Thinking Skills Test (CCTST). Posttesting was completed using these same instruments and an end-of-course comprehensive examination. Analysis of data revealed no significant differences between the experimental and control groups with regard to their overall achievement, their ability to process information, or their demonstration of critical thinking. It was interesting to note, however, that members of the experimental group did exhibit a change in their ability to select main ideas, apply deductive reasoning, and use inference. While the use of thinking strategies within the context of the course did not effect a significant change in academic achievement or critical thinking among at-risk community college students, it should be noted that application of a non-lecture method of class participation had no negative impact on student performance. Whether more abstruse changes have occurred with regard to the acquisition of cognitive skills remains to be elucidated.

Lymphatic Anatomy.

2016-12-01

Recent development of new lymphatic imaging and intervention techniques, such as intranodal lymphangiogram, dynamic contrast enhanced magnetic resonance lymphangiography and lymphatic embolization, have resulted in the resurgence of interest in the lymphatic anatomy. The lymphatic system is a continuous maze of interlacing vessels and lymph nodes and is extremely complex and variable. This presents a significant challenge for interpretation of imaging and performance of interventions on this system. There is an embryological reason for this complexity and variability; the lymphatic system sprouts off of primordia from several locations in the body, which later fuse together at different stages of development of the embryo. The lymphatic system can be divided in three distinct parts: soft tissue lymphatics, intestinal lymphatics, and liver lymphatics. Liver and intestinal lymphatics generate approximately 80% of the body lymph and are functionally the most important parts of the lymphatic system. However, their normal anatomy and pathological changes are relatively unknown. In this chapter we will explore the anatomy of these three systems relevant to lymphatic imaging and interventions.

Interactive teaching techniques have been used mainly in clinical teaching, with little attention given to their use in basic science teaching. With the aim of partially filling this gap, this study outlines an interactive approach to teaching anatomy based on the use of "brainstorming." The results of the students' critique of the teaching techniques are also included. Seventy-five students from the first-year nursing curriculum were tested by a structured questionnaire after three brainstorming sessions. The overall response to these sessions was very positive, indicating that students perceived this interactive technique as both interesting and useful. Furthermore, this approach may provide a useful strategy when learning the clinical courses of the upcoming academic years. Copyright 2002 Wiley-Liss, Inc.

The history and illustration of anatomy in the Middle Ages.

2013-11-01

This article reviews the influence of key figures on the pictorial representation of anatomy and the evolution of anatomical illustration during the Middle Ages until the time of the Renaissance, based on medical history books, journals and ancient medical books. During the early period in the Middle Ages, most illustrations were traditional drawings of emblematic nature, oftentimes unrealistic, not only because the precise knowledge of anatomy was lacking but also because the objective was to elucidate certain principles for teaching purposes. Five figure-series that came down to us through ancient manuscripts and textbooks represent the best examples of such traditional illustrations. With the advent of human dissection in the 13th and 14th centuries, a significant transformation in the depiction of anatomy began to project the practice of human dissection, as we see in the works of Mondino de Luzzi, Henri de Mondeville and Guido de Vigevano. After the invention of book printing in the second half of the 15th century, the reproduction of books was commonly practised and the woodcut made multiplication of pictures easier. Peter of Abano, Hieronymous Brunschwig, Johannes de Ketham, Johannes Peyligk, Gregory Reisch, Magnus Hundt, Laurentius Phryesen and many more included several anatomical illustrations in their treatises that demonstrated the development of anatomical illustration during the later Middle Ages.

The aim of this study was to analyze the topographical anatomy of the dorsal spinal cord (SC) in relation to the posterior median septum (PMS). This included the course and variations in the PMS, and its relationship to and distance from other dorsal spinal landmarks. Microsurgical anatomy of the PMS was examined in 12 formalin-fixed adult cadaveric SCs. Surface landmarks such as the dorsal root entry zone (DREZ), the denticulate ligament, the architecture of the leptomeninges and pial vascular distribution were noted. The PMS was examined histologically in all spinal segments. The PMS extended most deeply at spinal segments C7 and S4. This was statistically significant for all spinal segments except C5. The PMS was shallowest at segments T4 and T6, where it was statistically significantly thinner than at any other segment. In 80% of the SCs, small blood vessels were identified that traveled in a rostrocaudal direction in the PMS. The longest distance between the PMS and the DREZ was at the C1-C4 vertebral levels and the shortest distance was at the S5 level. Prevention of deficits following a dorsal midline neurosurgical approach to deep-seated SC lesions requires careful identification of the midline of the cord. The PMS and septum define the midline on the dorsum of the SC and their accurate identification is essential for a safe midline surgical approach. In this anatomical study, we describe the surface anatomy of the dorsal SC and its relationship with the PMS, which can be used to determine a safe entry zone into the SC. © 2014 Wiley Periodicals, Inc.

Effectiveness of a Radiographic Anatomy Software Application for Enhancing Learning of Veterinary Radiographic Anatomy.

Reiter, Rachel; Viehdorfer, Matt; Hescock, Kimmy; Clark, Terri; Nemanic, Sarah

The goal of this study was to determine the effectiveness of an interactive radiology software application that we developed to enhance learning of normal canine radiographic anatomy. All first-year veterinary medical students were eligible to participate in this subject pre-test-post-test experimental design. When presented with the software application, all students had completed two terms of gross anatomy in which the complete anatomy of the dog had been taught using a combination of lectures and laboratory dissections, including radiographic examples. The software application was divided into four body regions: front limb, hind limb, skull/spine, and thorax/abdomen, each with a learning mode and a quiz mode. Quizzes were composed of 15 questions drawn pseudo-randomly without repeat from all structures within a region (median 206 structures). Students were initially given the software application with only the quiz mode activated. After completing four quizzes, one for each body region, students were given access to the software application with both learning mode and quiz mode activated. Students were instructed to spend 30 minutes using the learning mode to study the radiographic anatomy of each region and to retake each quiz. Quiz scores after using the learning mode were significantly higher for each body region (p<.001), with a large effect size for all four regions (Cohen's d=0.83-1.56). These results suggest that this radiographic anatomy software application is an effective tool for students to use to learn normal radiographic anatomy.

Although cadavers constitute the gold standard for teaching anatomy to medical and health science students, there are substantial financial, ethical, and supervisory constraints on their use. In addition, although anatomy remains one of the fundamental areas of medical education, universities have decreased the hours allocated to teaching gross anatomy in favor of applied clinical work. The release of virtual (VR) and augmented reality (AR) devices allows learning to occur through hands-on immersive experiences. The aim of this research was to assess whether learning structural anatomy utilizing VR or AR is as effective as tablet-based (TB) applications, and whether these modes allowed enhanced student learning, engagement and performance. Participants (n = 59) were randomly allocated to one of the three learning modes: VR, AR, or TB and completed a lesson on skull anatomy, after which they completed an anatomical knowledge assessment. Student perceptions of each learning mode and any adverse effects experienced were recorded. No significant differences were found between mean assessment scores in VR, AR, or TB. During the lessons however, VR participants were more likely to exhibit adverse effects such as headaches (25% in VR P < 0.05), dizziness (40% in VR, P < 0.001), or blurred vision (35% in VR, P < 0.01). Both VR and AR are as valuable for teaching anatomy as tablet devices, but also promote intrinsic benefits such as increased learner immersion and engagement. These outcomes show great promise for the effective use of virtual and augmented reality as means to supplement lesson content in anatomical education.

Didactic lessons are only one part of the multimodal teaching strategies used in gross anatomy courses today. Increased emphasis is placed on providing more opportunities for students to develop lifelong learning and critical thinking skills during medical training. In a pilot program designed to promote more engaged and independent learning in anatomy, self-study modules were introduced to supplement human gross anatomy instruction at Joan C. Edwards School of Medicine at Marshall University. Modules use three-dimensional constructs to help students understand complex anatomical regions. Resources are self-contained in portable bins and are accessible at any time. Students use modules individually or in groups in a structured self-study format that augments material presented in lecture and laboratory. Pilot outcome data, measured by feedback surveys and examination performance statistics, suggest that the activity may be improving learning in gross anatomy. Positive feedback on both pre- and post-examination surveys showed that students felt the activity helped to increase their understanding of the topic. In concordance with student perception, average examination scores on module-related laboratory and lecture questions were higher in the two years of the pilot program compared with the year before its initiation. Modules can be fabricated on a modest budget using minimal resources, making implementation practical for smaller institutions. Upper level medical students assist in module design and upkeep, enabling continuous opportunities for vertical integration across the curriculum. This resource offers a feasible mechanism for enhancing independent and lifelong learning competencies, which could be a valuable complement to any gross anatomy curriculum. © 2014 American Association of Anatomists.

An improved understanding of the relationship between anatomy learning performance and approaches to learning can lead to the development of a more tailored approach to delivering anatomy teaching to medical students. This study investigated the relationship between learning style preferences, as measured by Visual, Aural, Read/write, and Kinesthetic (VARK) inventory style questionnaire and Honey and Mumford's learning style questionnaire (LSQ), and anatomy and clinical skills assessment performance at an Irish medical school. Additionally, mode of entry to medical school [undergraduate/direct-entry (DEM) vs. graduate-entry (GEM)], was examined in relation to individual learning style, and assessment results. The VARK and LSQ were distributed to first and second year DEM, and first year GEM students. DEM students achieved higher clinical skills marks than GEM students, but anatomy marks did not differ between each group. Several LSQ style preferences were shown to be weakly correlated with anatomy assessment performance in a program- and year-specific manner. Specifically, the "Activist" style was negatively correlated with anatomy scores in DEM Year 2 students (rs = -0.45, P = 0.002). The "Theorist" style demonstrated a weak correlation with anatomy performance in DEM Year 2 (rs = 0.18, P = 0.003). Regression analysis revealed that, among the LSQ styles, the "Activist" was associated with poorer anatomy assessment performance (P < 0.05), while improved scores were associated with students who scored highly on the VARK "Aural" modality (P < 0.05). These data support the contention that individual student learning styles contribute little to variation in academic performance in medical students.

This review focuses on how the study of anatomy in India has evolved through the centuries. Anatomical knowledge in ancient India was derived principally from animal sacrifice, chance observations of improperly buried human bodies, and examinations of patients made by doctors during treatment. The Vedic philosophies form the basis of the Ayurvedic tradition, which is considered to be one of the oldest known systems of medicine. Two sets of texts form the foundation of Ayurvedic medicine, the Susruta Samhita and the Charaka Samhita. The Susruta Samhita provided important surgical and anatomical information of the understanding of anatomy by Indians in the 6th century BCE. Here we review the anatomical knowledge known to this society. PMID:20887391

Animal models have been commonly used for in vivo and in vitro spinal research. However, the extent to which animal models resemble the human spine has not been well known. We conducted a systematic review to compare the morphometric features of vertebrae between human and animal species, so as to give some suggestions on how to choose an appropriate animal model in spine research. A literature search of all English language peer-reviewed publications was conducted using PubMed, OVID, Springer and Elsevier (Science Direct) for the years 1980-2008. Two reviewers extracted data on the anatomy of large animal spines from the identified articles. Each anatomical study of animals had to include at least three vertebral levels. The anatomical data from all animal studies were compared with the existing data of the human spine in the literature. Of the papers retrieved, seven were included in the review. The animals in the studies involved baboon, sheep, porcine, calf and deer. Distinct anatomical differences of vertebrae were found between the human and each large animal spine. In cervical region, spines of the baboon and human are more similar as compared to other animals. In thoracic and lumbar regions, the mean pedicle height of all animals was greater than the human pedicles. There was similar mean pedicle width between animal and the human specimens, except in thoracic segments of sheep. The human spinal canal was wider and deeper in the anteroposterior plane than any of the animals. The mean human vertebral body width and depth were greater than that of the animals except in upper thoracic segments of the deer. However, the mean vertebral body height was lower than that of all animals. This paper provides a comprehensive review to compare vertebrae geometries of experimental animal models to the human vertebrae, and will help for choosing animal model in vivo and in vitro spine research. When the animal selected for spine research, the structural similarities and

Anatomy and Physiology is a core course in pre-registration nursing programs, yet many students have difficulty successfully negotiating the large volume of content and the complex concepts in these bioscience courses. Typically students perform poorly in these 'threshold' courses', despite multiple interventions to support student engagement. Investigation of the shortcomings in these courses, based on feedback from students indicated several key areas of difficulty in the course, especially focused around a relative lack of hands-on 'concrete' activities in laboratories and tutorials. To attempt to address this, academic and technical staff developed activities for students that promoted discussion and allowed students to interact easily and repetitively with content. Interactive tables and posters that needed to be labelled or 'filled-in' using pre-prepared Velcro dots, as well as pre-prepared flash cards to promote group work, were some examples of the activities used to enhance student experiences and promote hands-on learning. Over the academic year of 2013 these activities were introduced into the laboratory and tutorial classes for first year Bachelor of Nursing anatomy and physiology students. Staff and student participants positively rated implementation of these new activities on surveys, as they allowed them to explore the difficult aspects of anatomy and physiology, utilising various learning styles that may have been neglected in the past.

Most anatomists agree that cadaver dissection serves as a superior teaching tool in human anatomy education. However, attitudes toward body donation vary widely between different individuals. A questionnaire was developed to determine the attitudes toward body and organ donation among those who learn the most from cadavers: medical students, medical student teaching assistants, medical students involved in research, and anatomy professors. A cross-sectional, prospective study was designed in which the questionnaire was distributed among first-year human anatomy students before undertaking cadaver dissection at the beginning of the semester, and then again after a commemoration service at the end of the course. The questionnaire items included demographic data, as well as questions designed to characterize participants' attitudes regarding body/organ donation from strangers, family members, and whether participants would consider such practices with their own bodies. Out of a total of 517 students enrolled in the Human Anatomy course in the Medical School at the Universidad Autónoma de Nuevo León, Mexico during January to June 2016, 95% responded to the first (491) and second (490) surveys. Participants' opinions on their own organ donation was similar before and after exposure to cadaver dissection, with between 87% and 81% in favor of such practices, and only 3% against it, in both surveys. Participants' willingness to donate their own bodies, as well as those of family members, increased, while reluctance regarding such practices decreased by half (P < 0.0001 and P < 0.05). Professors had the highest rates of positive opinions regarding their own body donation (74.9%), with 18.8% undecided. Low opposition toward organ and body donation remains prevalent among both anatomists and physicians in training in Mexico.

Anatomy of the clitoris.

2005-10-01

We present a comprehensive account of clitoral anatomy, including its component structures, neurovascular supply, relationship to adjacent structures (the urethra, vagina and vestibular glands, and connective tissue supports), histology and immunohistochemistry. We related recent anatomical findings to the historical literature to determine when data on accurate anatomy became available. An extensive review of the current and historical literature was done. The studies reviewed included dissection and microdissection, magnetic resonance imaging (MRI), 3-dimensional sectional anatomy reconstruction, histology and immunohistochemical studies. The clitoris is a multiplanar structure with a broad attachment to the pubic arch and via extensive supporting tissue to the mons pubis and labia. Centrally it is attached to the urethra and vagina. Its components include the erectile bodies (paired bulbs and paired corpora, which are continuous with the crura) and the glans clitoris. The glans is a midline, densely neural, non-erectile structure that is the only external manifestation of the clitoris. All other components are composed of erectile tissue with the composition of the bulbar erectile tissue differing from that of the corpora. The clitoral and perineal neurovascular bundles are large, paired terminations of the pudendal neurovascular bundles. The clitoral neurovascular bundles ascend along the ischiopubic rami to meet each other and pass along the superior surface of the clitoral body supplying the clitoris. The neural trunks pass largely intact into the glans. These nerves are at least 2 mm in diameter even in infancy. The cavernous or autonomic neural anatomy is microscopic and difficult to define consistently. MRI complements dissection studies and clarifies the anatomy. Clitoral pharmacology and histology appears to parallel those of penile tissue, although the clinical impact is vastly different. Typical textbook descriptions of the clitoris lack detail and

Recognition of anatomical landmarks in live animals (and humans) is key for clinical practice, but students often find it difficult to translate knowledge from dissection-based anatomy onto the live animal and struggle to acquire this vital skill. The purpose of this study was to create and evaluate the use of an equine anatomy rug ("Anato-Rug") depicting topographical anatomy and key areas of lung, heart, and gastrointestinal auscultation, which could be used together with a live horse to aid learning of "live animal" anatomy. Over the course of 2 weeks, 38 third year veterinary students were randomly allocated into an experimental group, revising topographical anatomy from the "Anato-Rug," or a control group, learning topographical anatomy from a textbook. Immediately post activity, both groups underwent a test on live anatomy knowledge and were retested 1 week later. Both groups then completed a questionnaire to ascertain their perceptions of their learning experiences. Results showed that the experimental groups scored significantly higher than the control group at the first testing session, experienced more enjoyment during the activity and gained more confidence in identifying anatomical landmarks than the control group. There was not a significant difference in scores between groups at the second testing session. The findings indicate that the anatomy rug is an effective learning tool that aids understanding, confidence, and enjoyment in learning equine thorax and abdominal anatomy; however it was not better than traditional methods with regards to longer term memory recall.

Orsbon, Courtney P; Kaiser, Rebecca S; Ross, Callum F

2014-01-01

Pre-clinical anatomy curricula must provide medical students with the knowledge needed in a variety of medical and surgical specialties. But do physicians within specialties agree about what anatomical knowledge is most important in their practices? And, what is the common core of anatomical knowledge deemed essential by physicians in different specialties? Answers to these questions would be useful in designing pre-clinical anatomy courses. The primary aim of this study was to assess the importance of a human gross anatomy course by soliciting the opinions of physicians from a range of specialties. We surveyed 93 physicians to determine the importance of specific anatomical topics in their own practices. Their responses were analyzed to assess variation in intra- and inter-departmental attitudes toward the importance of anatomy. Nearly all of the topics taught in the course were deemed important by the clinicians as a group, but respondents showed little agreement on the rank order of importance of anatomical topics. Overall, only medical imaging received high importance by nearly all respondents, and lower importance was attached to embryology and lymphatic anatomy. Our survey data, however, also suggested distinct hierarchies in the importance assigned to anatomical topics within specialties. Given that physicians view the importance of anatomy differently, we suggest that students revisit anatomy through a vertically integrated curriculum tailored to provide specialty-specific anatomical training to advanced students based on their areas of clinical interest. Integration of medical imaging into pre-clinical anatomy courses, already underway in many medical schools, is of high clinical relevance. © 2013 American Association of Anatomists.

The study aims to investigate anatomy learning styles and strategies of Jordanian and Malaysian medical students at the Jordan University of Science and Technology. The study is a cross-sectional questionnaire-based study. Students' responses for the questionnaire were numerically coded, and the results were analyzed to reveal statistically significant differences between Jordanian and Malaysian students. The results showed that Jordanian medical students were less interested in using cadavers in learning anatomy than Malaysian medical students. However, similar to their Malaysian counterparts, they prefer to employ other tools to learn anatomy like plastinated models and Internet-based resources. In addition to the aforementioned tools, Malaysian students were more interested in using cross-sectional images and making their own revision cards. Both Jordanian and Malaysian medical students were more interested in learning anatomy through clinical cases, and by system rather than by region. Moreover, it was revealed that Jordanian medical students learn anatomy more efficiently when they formulate a general view of a particular topic. Both Jordanian and Malaysian medical students also relied on reciting definitions and memorizing facts to learn anatomy. The study also reported significant differences between Jordanian and Malaysian students' perspectives on learning anatomy. The findings of the study suggest that Jordanian and Malaysian medical students posses different cultures of learning. Jordanian anatomy instructors need to consider these different learning cultures when they prepare their instructional methods and teaching materials to fulfill the educational needs of their culturally diverse students.

Clinical anatomy of the subserous layer: An amalgamation of gross and clinical anatomy.

PubMed

Yabuki, Yoshihiko

2016-05-01

The 1998 edition of Terminologia Anatomica introduced some currently used clinical anatomical terms for the pelvic connective tissue or subserous layer. These innovations persuaded the present author to consider a format in which the clinical anatomical terms could be reconciled with those of gross anatomy and incorporated into a single anatomical glossary without contradiction or ambiguity. Specific studies on the subserous layer were undertaken on 79 Japanese women who had undergone surgery for uterine cervical cancer, and on 26 female cadavers that were dissected, 17 being formalin-fixed and 9 fresh. The results were as follows: (a) the subserous layer could be segmentalized by surgical dissection in the perpendicular, horizontal and sagittal planes; (b) the segmentalized subserous layer corresponded to 12 cubes, or ligaments, of minimal dimension that enabled the pelvic organs to be extirpated; (c) each ligament had a three-dimensional (3D) structure comprising craniocaudal, mediolateral, and dorsoventral directions vis-á-vis the pelvic axis; (d) these 3D-structured ligaments were encoded morphologically in order of decreasing length; and (e) using these codes, all the surgical procedures for 19th century to present-day radical hysterectomy could be expressed symbolically. The establishment of clinical anatomical terms, represented symbolically through coding as demonstrated in this article, could provide common ground for amalgamating clinical anatomy with gross anatomy. Consequently, terms in clinical anatomy and gross anatomy could be reconciled and compiled into a single anatomical glossary. © 2015 Wiley Periodicals, Inc.

Medical student preferences for self-directed study resources in gross anatomy.

Gross anatomy instruction in medical curricula involve a range of resources and activities including dissection, prosected specimens, anatomical models, radiological images, surface anatomy, textbooks, atlases, and computer-assisted learning (CAL). These resources and activities are underpinned by the expectation that students will actively engage in self-directed study (SDS) to enhance their knowledge and understanding of anatomy. To gain insight into preclinical versus clinical medical students' preferences for SDS resources for learning gross anatomy, and whether these vary on demographic characteristics and attitudes toward anatomy, students were surveyed at two Australian medical schools, one undergraduate-entry and the other graduate-entry. Lecture/tutorial/practical notes were ranked first by 33% of 156 respondents (mean rank ± SD, 2.48 ± 1.38), textbooks by 26% (2.62 ± 1.35), atlases 20% (2.80 ± 1.44), videos 10% (4.34 ± 1.68), software 5% (4.78 ± 1.50), and websites 4% (4.24 ± 1.34). Among CAL resources, Wikipedia was ranked highest. The most important factor in selecting CAL resources was cost (ranked first by 46%), followed by self-assessment, ease of use, alignment with curriculum, and excellent graphics (each 6-9%). Compared with preclinical students, clinical students ranked software and Acland's Video Atlas of Human Anatomy higher and felt radiological images were more important in selecting CAL resources. Along with other studies reporting on the quality, features, and impact on learning of CAL resources, the diversity of students' preferences and opinions on usefulness and ease of use reported here can help guide faculty in selecting and recommending a range of CAL and other resources to their students to support their self-directed study. © 2015 American Association of Anatomists.

This study was conducted to assess the relative usefulness of canine intestinal contents and simulated media in the prediction of solubility of two weak bases (dipyridamole and ketoconazole) in fasted and fed human intestinal aspirates that were collected under conditions simulating those in bioavailability/bioequivalence studies. After administration of 250 mL of water or 500 mL of Ensure plus [both containing 10 mg/mL polyethylene glycol (PEG) 4000 as nonabsorbable marker], intestinal aspirates were collected from the fourth part of the duodenum of 12 healthy adults and from the mid-jejunum of four Labradors. Pooled samples were analyzed for PEG, pH, buffer capacity, osmolality, surface tension, pepsin, total carbohydrates, total protein content, bile salts, phospholipids, and neutral lipids. The shake-flask method was used to measure the solubility of dipyridamole and ketoconazole in pooled human and canine intestinal contents and in fasted-state-simulating intestinal fluid (FaSSIF) and fed-state-simulating intestinal fluid (FeSSIF) containing various bile salts and pH-buffering agents. For both compounds, solubility in canine contents may be predictive of human intralumenal solubility in the fasting state but not in the fed state. The poor agreement of results in canine and human aspirates can be attributed to the higher bile salt content in canine bile. Solubility in FaSSIF containing a mixture of bile salts from crude bile predicted satisfactorily the intralumenal solubility of both drugs in the fasted state in humans. Solubility in FeSSIF, regardless of the identity of bile salts or of the buffering species, deviated from intralumenal values in the fed human aspirates by up to 40%. This was attributed to the lack of lipolytic products in FeSSIF, the higher bile salt content of FeSSIF, and the lower pH of FeSSIF. FaSSIF containing a mixture of bile salts from crude bile, and FeSSIF containing lipolytic products and, perhaps, having lower bile salt content but

Certain negative factors such as fear, loss of concentration and interest in the course, lack of confidence, and undue stress have been associated with the study of anatomy. These are factors most often provoked by the unusually large curriculum, nature of the course, and the psychosocial impact of dissection. As a palliative measure, Anatomy Adventure, a board game on anatomy was designed to reduce some of these pressures, emphasize student centered and collaborative learning styles, and add fun to the process of learning while promoting understanding and retention of the subject. To assess these objectives, 95 out of over 150 medical and dental students who expressed willingness to be part of the study were recruited and divided into a Game group and a Non-game group. A pretest written examination was given to both groups, participants in the Game group were allowed to play the game for ten days, after which a post-test examination was also given. A 20-item questionnaire rated on a three-point scale to access student's perception of the game was given to the game group. The post-test scores of the game group were significantly higher (P < 0.05) than those of the non-game counterparts. Also the post-test score of the game based group was significantly better (P < 0.05) than their pretest. The students in their feedback noted in very high proportions that the game was interesting, highly informative, encouraged team work, improved their attitude, and perception to gross anatomy. © 2013 American Association of Anatomists.

It is shown that the infrared irradiation decreases the content of β-carotene and lycopene carotenoids in human skin. A decrease in the content of β-carotene and lycopene may indicate that the IR radiation, as well as the UV radiation, is capable of forming free radicals in human skin. The investigations were performed in vivo using the technique of resonance Raman scattering developed by us for the noninvasive determination of antioxidant potential in skin.

Clinical Anatomy of the Lingual Nerve: A Review.

2017-05-01

Knowledge of lingual nerve anatomy is of paramount importance to dental practitioners and maxillofacial surgeons. The purpose of this article is to review lingual nerve anatomy from the cranial base to its insertion in the tongue and provide a more detailed explanation of its course to prevent procedural nerve injuries. Fifteen human cadavers from the University of Alabama at Birmingham School of Medicine's Anatomical Donor Program were reviewed. The anatomic structures and landmarks were identified and confirmed by anatomists. Lingual nerve dissection was carried out and reviewed on 15 halved human cadaver skulls (total specimens, 28). Cadaveric dissection provides a detailed examination of the lingual nerve from the cranial base to tongue insertion. The lingual nerve receives the chorda tympani nerve approximately 1 cm below the bifurcation of the lingual and inferior alveolar nerves. The pathway of the lingual nerve is in contact with the periosteum of the mandible just behind the internal oblique ridge. The lingual nerve crosses the submandibular duct at the interproximal space between the mandibular first and second molars. The submandibular ganglion is suspended from the lingual nerve at the distal area of the second mandibular molar. A zoning classification is another way to more accurately describe the lingual nerve based on close anatomic landmarks as seen in human cadaveric specimens. This system could identify particular areas of interest that might be at greater procedural risk. Published by Elsevier Inc.

Purpose The purpose of this study is to provide better understanding as to how the "double" vascular arcades, in contrast to other intestinal marginal vessels, develop along the right margin of the pancreatic head. Materials and Methods In human fetuses between 8-30 weeks, we described the topographical anatomy of the vessels, bile duct, duodenum as well as the ventral and dorsal primordia of the pancreatic head with an aid of pancreatic polypeptide immunohisto-chemistry. Results The contents of the hepatoduodenal ligament crossed the superior side of the pylorus. Moreover, the right hepatic artery originating from the superior mesenteric artery ran along the superior aspect of the pancreatic head. An arterial arcade, corresponding to the posterior pancreaticoduodenal arteries, encircled the superior part of the pancreatic head, whereas another arcade, corresponding to the anterior pancreaticoduodenal arteries, surrounded the inferior part. The dorsal promordium of the pancreas surrounded and/or mixed the ventral primordium at 13-16 weeks. Thus, both arterial arcades were likely to attach to the dorsal primordium. Conclusion The fetal anatomy of the pancreaticoduodenal vascular arcades as well as that of the hepatoduodenal ligament were quite different from adults in topographical relations. Thus, in the stage later than 30 weeks, further rotation of the duodenum along a horizontal axis seemed to be required to move the pylorus posterosuperiorly and to reflect the superior surface of the pancreatic head posteriorly. However, to change the topographical anatomy of the superior and inferior arterial arcades into the final position, re-arrangement of the pancreatic parenchyma might be necessary in the head.

The use of cadavers in human anatomy teaching requires adequate number of anatomy instructors who can provide close supervision of the students. Most medical schools are facing challenges of lack of trained individuals to teach anatomy. Innovative techniques are therefore needed to impart adequate and relevant anatomical knowledge and skills. This study was conducted in order to evaluate the traditional teaching method and reciprocal peer teaching (RPT) method during anatomy dissection. Debriefing surveys were administered to the 227 first year medical students regarding merits, demerits and impact of both RPT and Traditional teaching experiences on student's preparedness prior to dissection, professionalism and communication skills. Out of this, 159 (70 %) completed the survey on traditional method while 148 (65.2 %) completed survey on RPT method. An observation tool for anatomy faculty was used to assess collaboration, professionalism and teaching skills among students. Student's scores on examinations done before introduction of RPT were compared with examinations scores after introduction of RPT. Our results show that the mean performance of students on objective examinations was significantly higher after introduction of RPT compared to the performance before introduction of RPT [63.7 ± 11.4 versus 58.6 ± 10, mean difference 5.1; 95 % CI = 4.0-6.3; p-value < 0.0001]. Students with low performance prior to RPT benefited more in terms of examination performance compared to those who had higher performance [Mean difference 7.6; p-value < 0.0001]. Regarding student's opinions on traditional method versus RPT, 83 % of students either agreed or strongly agreed that they were more likely to read the dissection manual before the RPT dissection session compared to 35 % for the traditional method. Over 85 % of respondents reported that RPT improved their confidence and ability to present information to peers and faculty compared to 38 % for

Systematic research on the history of anatomy in National Socialism (NS) has only started in recent years. It has shown that anatomists used the bodies of NS victims for anatomical teaching and research purposes. In this they became complicit with the NS regime. There was a high percentage of Nazi party members among the anatomists, but at the same time there were anatomists whose careers were disrupted for so-called "racial" and political reasons. Decisive aspects of this history are first, the fact that traditional sources of anatomical body procurement included increasing numbers of NS victims and second, the gradual change of the traditional anatomical paradigm of working with the dead to a new paradigm of working with the "future dead" in human experimentation. This history has importance for the development of new ethical guidelines in anatomy.

The need to increase the efficiency of dissection in the gross anatomy laboratory has been the driving force behind the technologic changes we have recently implemented. With the introduction of an integrated systems-based medical curriculum and a reduction in laboratory teaching hours, anatomy faculty at the University of North Texas Health Science Center (UNTHSC) developed a computer-based dissection manual to adjust to these curricular changes and time constraints. At each cadaver workstation, Apple iMac computers were added and a new dissection manual, running in a browser-based format, was installed. Within the text of the manual, anatomical structures required for dissection were linked to digital images from prosected materials; in addition, for each body system, the dissection manual included images from cross sections, radiographs, CT scans, and histology. Although we have placed a high priority on computerization of the anatomy laboratory, we remain strong advocates of the importance of cadaver dissection. It is our belief that the utilization of computers for dissection is a natural evolution of technology and fosters creative teaching strategies adapted for anatomy laboratories in the 21st century. Our strategy has significantly enhanced the independence and proficiency of our students, the efficiency of their dissection time, and the quality of laboratory instruction by the faculty.

Anatomy and Aesthetics of the Labia Minora: The Ideal Vulva?

PubMed

Clerico, C; Lari, A; Mojallal, A; Boucher, F

2017-06-01

Female genital cosmetic surgery is becoming more and more widespread both in the field of plastic and gynaecological surgery. The increased demand for vulvar surgery is spurred by the belief that the vulva is abnormal in appearance. What is normal in terms of labial anatomy? Labia minora enlargement or hypertrophy remains a clinical diagnosis which is poorly defined as it could be considered a variation of the normal anatomy. Enlarged labia minora can cause functional, aesthetic and psychosocial problems. In reality, given the wide variety of vulvar morphology among people, it is a very subjective issue to define the "normal" vulva. The spread of nudity in the general media plays a major role in creating an artificial image and standards with regard to the ideal form. Physicians should be aware that the patient's self-perception of the normal or ideal vulva is highly influenced by the arguably distorted image related to our socio-psychological environment, as presented to us by the general media and internet. As physicians, we have to educate our patients on the variation of vulvar anatomy and the potential risks of these surgeries.

Architectural production has been influenced by a variety of sources. Forms derived from nature, biology and live organisms, had often been utilised in art and architecture. Certain features of the human anatomy had been reflected in design process in various ways, as imitations, abstractions, interpretations of the reality. The correlation of ideal proportions had been investigated throughout centuries. Scholars, art historians starting with Vitruvius from the world of ancient Roman architecture, described the human figure as being the principal source of proportion among the classical orders of architecture. This study aims to investigate two contemporary buildings, namely Kiasma Museum in Helsinki and Eye Museum in Amsterdam, inspired directly from the anatomy of visual system. Morover the author discussed the relationship of biology and architecture through these two special buildings by viewing the eye and chiasma as metaphors for elements of architecture.

Adaptive self-organization in the embryo: its importance to adult anatomy and to tissue engineering.

PubMed

Davies, Jamie A

2018-04-01

The anatomy of healthy humans shows much minor variation, and twin-studies reveal at least some of this variation cannot be explained genetically. A plausible explanation is that fine-scale anatomy is not specified directly in a genetic programme, but emerges from self-organizing behaviours of cells that, for example, place a new capillary where it happens to be needed to prevent local hypoxia. Self-organizing behaviour can be identified by manipulating growing tissues (e.g. putting them under a spatial constraint) and observing an adaptive change that conserves the character of the normal tissue while altering its precise anatomy. Self-organization can be practically useful in tissue engineering but it is limited; generally, it is good for producing realistic small-scale anatomy but large-scale features will be missing. This is because self-organizing organoids miss critical symmetry-breaking influences present in the embryo: simulating these artificially, for example, with local signal sources, makes anatomy realistic even at large scales. A growing understanding of the mechanisms of self-organization is now allowing synthetic biologists to take their first tentative steps towards constructing artificial multicellular systems that spontaneously organize themselves into patterns, which may soon be extended into three-dimensional shapes. © 2017 The Authors Journal of Anatomy published by John Wiley & Sons Ltd on behalf of Anatomical Society.

2015-01-01

The femoral enthesis of the human anterior cruciate ligament (ACL) is known to be more susceptible to injury than the tibial enthesis. To determine whether anatomic differences might help explain this difference, we quantified the microscopic appearance of both entheses in 15 unembalmed knee specimens using light microscopy, toluidine blue stain and image analysis. The amount of calcified fibrocartilage and uncalcified fibrocartilage, and the ligament entheseal attachment angle were then compared between the femoral and tibial entheses via linear mixed-effects models. The results showed marked differences in anatomy between the two entheses. The femoral enthesis exhibited a 3.9-fold more acute ligament attachment angle than the tibial enthesis (p < 0.001), a 43% greater calcified fibrocartilage tissue area (p < 0.001), and a 226% greater uncalcified fibrocartilage depth (p < 0.001), with the latter differences being particularly pronounced in the central region. We conclude that the ACL femoral enthesis has more fibrocartilage and a more acute ligament attachment angle than the tibial enthesis, which provides insight into why it is more vulnerable to failure.

The aim of this article is to introduce a great physician of the late Ottoman period and his writings on spinal anatomy. The article presents chapters related to the anatomy of vertebra and the vertebral column in the book of Şanizade Ataullah Mehmed, Mir'āt al-Abdān fı Tashrıḥ-i A'ḍāi'l-Insān (Mirror of the Bodies in the Dissection of the Members of the Human Body). Works of Şanizade are viewed as important landmarks in Turkish medical history. Anatomy education in Turkey can be divided into four historic periods and the second period is called the Şanizade Period (1816-1827). This period leads up to the opening of the first modern medical school in Turkey on March 14, 1827. The most important characteristic of Şanizade's work is that it is the first illustrated anatomy book printed in the Ottoman Age, and the value of the work is shown by Şanizade being one of the originators of medical terms in Ottoman Medicine.

Numeric and symbolic knowledge representation of cerebral cortex anatomy: methods and preliminary results.

PubMed

Dameron, O; Gibaud, B; Morandi, X

2004-06-01

The human cerebral cortex anatomy describes the brain organization at the scale of gyri and sulci. It is used as landmarks for neurosurgery as well as localization support for functional data analysis or inter-subject data comparison. Existing models of the cortex anatomy either rely on image labeling but fail to represent variability and structural properties or rely on a conceptual model but miss the inner 3D nature and relations of anatomical structures. This study was therefore conducted to propose a model of sulco-gyral anatomy for the healthy human brain. We hypothesized that both numeric knowledge (i.e., image-based) and symbolic knowledge (i.e., concept-based) have to be represented and coordinated. In addition, the representation of this knowledge should be application-independent in order to be usable in various contexts. Therefore, we devised a symbolic model describing specialization, composition and spatial organization of cortical anatomical structures. We also collected numeric knowledge such as 3D models of shape and shape variation about cortical anatomical structures. For each numeric piece of knowledge, a companion file describes the concept it refers to and the nature of the relationship. Demonstration software performs a mapping between the numeric and the symbolic aspects for browsing the knowledge base.

Structural neuroimaging of humans with typical and atypical sex-chromosome complements has established the marked influence of both Yand X-/Y-chromosome dosage on total brain volume (TBV) and identified potential cortical substrates for the psychiatric phenotypes associated with sex-chromosome aneuploidy (SCA). Here, in a cohort of 354 humans with varying karyotypes (XX, XY, XXX, XXY, XYY, XXYY, XXXXY), we investigate sex and SCA effects on subcortical size and shape; focusing on the striatum, pallidum and thalamus. We find large effect-size differences in the volume and shape of all three structures as a function of sex and SCA. We correct for TBV effects with a novel allometric method harnessing normative scaling rules for subcortical size and shape in humans, which we derive here for the first time. We show that all three subcortical volumes scale sublinearly with TBV among healthy humans, mirroring known relationships between subcortical volume and TBV among species. Traditional TBV correction methods assume linear scaling and can therefore invert or exaggerate sex and SCA effects on subcortical anatomy. Allometric analysis restricts sex-differences to: (1) greater pallidal volume (PV) in males, and (2) relative caudate head expansion and ventral striatum contraction in females. Allometric analysis of SCA reveals that supernumerary X- and Y-chromosomes both cause disproportionate reductions in PV, and coordinated deformations of striatopallidal shape. Our study provides a novel understanding of sex and sex-chromosome dosage effects on subcortical organization, using an allometric approach that can be generalized to other basic and clinical structural neuroimaging settings.

Evolution of the Human Pelvis.

Rosenberg, Karen R; DeSilva, Jeremy M

2017-05-01

No bone in the human postcranial skeleton differs more dramatically from its match in an ape skeleton than the pelvis. Humans have evolved a specialized pelvis, well-adapted for the rigors of bipedal locomotion. Precisely how this happened has been the subject of great interest and contention in the paleoanthropological literature. In part, this is because of the fragility of the pelvis and its resulting rarity in the human fossil record. However, new discoveries from Miocene hominoids and Plio-Pleistocene hominins have reenergized debates about human pelvic evolution and shed new light on the competing roles of bipedal locomotion and obstetrics in shaping pelvic anatomy. In this issue, 13 papers address the evolution of the human pelvis. Here, we summarize these new contributions to our understanding of pelvic evolution, and share our own thoughts on the progress the field has made, and the questions that still remain.

The cynomolgus monkey (Macaca fascicularis) was used to establish a preclinical model of genetically modified hepatocytes auto transplantation. Here, we report information gleaned from careful observation and notes obtained from 59 female cynomolgus monkeys undergoing 44 anatomical hepatic resections, 12 main portal vein division dissections and selective branch ligations, and 46 portographies. Additionally, three anatomical liver dissections after total resection at autopsy were performed and served to confirm peroperative observations and for photography to provide illustrations. Our results indicate that the cynomolgus monkey liver has four lobes: the median (the largest), the right and left lateral, and the caudate lobes. In 60% (N=20) of individuals the portal bifurcates into right and left portal veins, in the remaining 40% (N=14) the portal vein trifurcates into right anterior, right posterior, and left portal veins. The anatomy and branching pattern of the hepatic artery and bile ducts closely follow those of the portal branches. Functionally, the cynomolgus monkey liver can be divided into eight independent segments. Thus, we report the first detailed description of the hepatic and portal surgical anatomy of the cynomolgus monkey. The cynomolgus monkey liver is more similar to the human liver than are livers of any small or large nonprimate mammals that have been described. (c) 2009 Wiley-Liss, Inc.

Victor Papilian was born an artist, during high school he studied music in order to become a violinist in two professional orchestras in Bucharest. Later on he enrolled in the school of medicine, being immediately attracted by anatomy. After graduating, with a briliant dissertation, he became a member of the faculty and continued to teach in his preferred field. His masters, Gh. Marinescu and Victor Babes, proposed him for the position of professor at the newly established Faculty of Medicine of Cluj. Here he reorganized the department radically, created an anatomy museum and edited the first dissection handbook and the first Romanian anatomy (descriptive and topographic) treatise, both books received with great appreciation. He received the Romanian Academy Prize. His knowledge and skills gained him a well deserved reputation and he created a prestigious school of anatomy. He published over 250 scientific papers in national and international journals, ranging from morphology to functional, pathological and anthropological topics. He founded the Society of Anthropology, with its own newsletter; he was elected as a member of the French Society of Anatomy. In parallel he had a rich artistic and cultural activity as writer and playwright: he was president of the Transylvanian Writers' Society, editor of a literary review, director of the Cluj theater and opera, leader of a book club and founder of a symphony orchestra.

Augmented Realty (AR) offers a novel method of blending virtual and real anatomy for intuitive spatial learning. Our first aim in the study was to create a prototype AR tool for mobile devices. Our second aim was to complete a technical evaluation of our prototype AR tool focused on measuring the system's ability to accurately render digital content in the real world. We imported Computed Tomography (CT) data derived virtual surface models into a 3D Unity engine environment and implemented an AR algorithm to display these on mobile devices. We investigated the accuracy of the virtual renderings by comparing a physical cube with an identical virtual cube for dimensional accuracy. Our comparative study confirms that our AR tool renders 3D virtual objects with a high level of accuracy as evidenced by the degree of similarity between measurements of the dimensions of a virtual object (a cube) and the corresponding physical object. We developed an inexpensive and user-friendly prototype AR tool for mobile devices that creates highly accurate renderings. This prototype demonstrates an intuitive, portable, and integrated interface for spatial interaction with virtual anatomical specimens. Integrating this AR tool with a library of CT derived surface models provides a platform for spatial learning in the anatomy curriculum. The segmentation methodology implemented to optimize human CT data for mobile viewing can be extended to include anatomical variations and pathologies. The ability of this inexpensive educational platform to deliver a library of interactive, 3D models to students worldwide demonstrates its utility as a supplemental teaching tool that could greatly benefit anatomical instruction.

Locomotion and basicranial anatomy in primates and marsupials.

PubMed

Villamil, Catalina I

2017-10-01

There is ongoing debate in paleoanthropology about whether and how the anatomy of the cranium, and especially the cranial base, is evolving in response to locomotor and postural changes. However, the majority of studies focus on two-dimensional data, which fails to capture the complexity of cranial anatomy. This study tests whether three-dimensional cranial base anatomy is linked to locomotion or to other factors in primates (n = 473) and marsupials (n = 231). Results indicate that although there is a small effect of locomotion on cranial base anatomy in primates, this is not the case in marsupials. Instead, facial anatomy likely drives variation in cranial base anatomy in both primates and marsupials, with additional roles for body size and brain size. Although some changes to foramen magnum position and orientation are phylogenetically useful among the hominoids, they do not necessarily reflect locomotion or positional behavior. The interplay between locomotion, posture, and facial anatomy in primates requires further investigation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Human cranial anatomy and the differential preservation of population history and climate signatures.

Harvati, Katerina; Weaver, Timothy D

2006-12-01

Cranial morphology is widely used to reconstruct evolutionary relationships, but its reliability in reflecting phylogeny and population history has been questioned. Some cranial regions, particularly the face and neurocranium, are believed to be influenced by the environment and prone to convergence. Others, such as the temporal bone, are thought to reflect more accurately phylogenetic relationships. Direct testing of these hypotheses was not possible until the advent of large genetic data sets. The few relevant studies in human populations have had intriguing but possibly conflicting results, probably partly due to methodological differences and to the small numbers of populations used. Here we use three-dimensional (3D) geometric morphometrics methods to test explicitly the ability of cranial shape, size, and relative position/orientation of cranial regions to track population history and climate. Morphological distances among 13 recent human populations were calculated from four 3D landmark data sets, respectively reflecting facial, neurocranial, and temporal bone shape; shape and relative position; overall cranial shape; and centroid sizes. These distances were compared to neutral genetic and climatic distances among the same, or closely matched, populations. Results indicate that neurocranial and temporal bone shape track neutral genetic distances, while facial shape reflects climate; centroid size shows a weak association with climatic variables; and relative position/orientation of cranial regions does not appear correlated with any of these factors. Because different cranial regions preserve population history and climate signatures differentially, caution is suggested when using cranial anatomy for phylogenetic reconstruction.

Pancreatic cancer is the fourth cause of death by cancer worldwide. Lymph node (LN) involvement is known to be the main prognostic factor. However, lymphatic anatomy is complex and only partially characterized. The aim of the study was to study the pancreatic lymphatic system using computer-assisted anatomic dissection (CAAD) technique and also to update CAAD technique by automatizing slice alignment. We dissected three human fetuses aged from 18 to 34 WA. 5-µm serial sections of duodeno-pancreas and spleen blocks were stained (hematoxylin-eosin, hematoxylin of Mayer and Masson trichrome), scanned, aligned and modeled in three dimensions. We observed a rich, diffuse but not systematized lymphatic network in the peri-pancreatic region. There was an equal distribution of LNs between the cephalic and body-tail portions. The lymphatic vascularization appeared in continuity from the celiac trunk to the distal ends of its hepatic and splenic arterial branches parallel to the nerve ramifications of the celiac plexus. We also observed a continuity between the drainage of the pancreatic head and the para-aortic region posteriorly. In view of the wealth of peri-pancreatic LNs, the number of LNs to harvest could be increased to improve nodal staging and prognostic evaluation. Pancreatic anatomy as described does not seem to be compatible with the sentinel LN procedure in pancreatic surgery. Finally, we are now able to offer an alternative to manual alignment with a semi-automated alignment.

The current status of anatomy knowledge: where are we now? Where do we need to go and how do we get there?

Gross anatomy is no longer considered a science, as it is no longer considered a research-led discipline. Looking to the current status of anatomical teaching, there is worldwide unanimity regarding the steady decline in the provision of contact hours of this basic science in a crowded undergraduate curriculum. The same could apply at the postgraduate level for specialties where surgical anatomy is essential. The long-term consequence of this shortage of optimal anatomical knowledge is thought to have implications on patient safety. Where are we now? Anatomy has been, and is still, severely affected by a content and extent reduction policy in most medical schools. Such suboptimal anatomy education has been linked to an increase in some types of medico-legal claims. This could be due in part to the rapid rise of modern learning approaches, lack of gross anatomy teachers, and lack of structured programs. Which direction are we taking, and where do we need to go? The introduction of surface anatomy at the undergraduate level, the implementation of surgical anatomy courses at the postgraduate level, and the revival of dissection courses at both levels could be measures that change the direction of the actual status. How do we get there? (a) The implementation of a national anatomy core curriculum by local medical education societies with a requirement stating the provision of a clinically oriented surface anatomy course. (b) Making room for the time-tested dissection method to be taught in gross anatomy at both levels. (c) The development of explicit and formal teaching in surgical anatomy via postgraduate courses for the concerned specialties. (d) An evaluation of the 3D visualization technology and surgical simulation applied to anatomy teaching. The current suboptimal anatomy knowledge should be acknowledged, and ways to change the course should be searched for. I present my views for possible and practical solutions by introducing surface anatomy at an

Medical Students' Assessment of Eduard Pernkopf's Atlas: Topographical Anatomy of Man.

To date, there has been no study examining the perceptions of first-year medical students regarding Eduard Pernkopf's atlas, particularly during their study of gross anatomy and prior to coursework in medical ethics. We present a discussion of Pernkopf's Atlas: Topographical Anatomy of Man from the perspective of U.S. medical students, and sought to determine whether medical students view Pernkopf's Topographical Anatomy of Man as a resource of greater accuracy, detail, and potential educational utility as compared to Netter's Atlas of Human Anatomy. The entire first-year class at Drexel University College of Medicine (265 students) was surveyed at approximately the midpoint of their gross anatomy course and 192 responses were collected (72% response rate). Of these, 176 (95%) were unaware of the existence of Pernkopf's atlas. Another 71% of students found the Pernkopf atlas more likely complete and accurate, whereas 76% thought the Netter atlas more useful for learning (p<.001). When presented with a hypothetical scenario in which the subjects used in creating Pernkopf's atlas were donated, or unclaimed, but with knowledge that Pernkopf was an active member of the Nazi party, 133 students (72%) retained their original position (p=.001). About 94% desired discussion of Pernkopf within a medical school bioethics course. The relationship between level of self-reported knowledge and whether or not students would advocate removal of the atlas was statistically significant (p=.013). Discussing ethical violations in medical history, especially the Pernkopf atlas, must attain a secure place in medical school curricula, and more specifically, within a bioethics course.

The teaching of human head, neck and orbital anatomy forms a critical part of undergraduate and postgraduate medical and allied health professional training, including optometry. While still largely grounded in cadaveric dissection, this method of instruction is constrained in some countries and regional areas by access to real human cadavers, costs of cadaver bequest programmes, health and safety of students and staff and the shortage of adequate time in modern curricula. Many candidates choosing a postgraduate pathway in ophthalmological training, such as those accepted into the Royal Colleges of Ophthalmology in the UK, Australia and New Zealand programmes and the American Academy of Ophthalmologists in the USA, are compelled as adult learners to revise or revisit human orbital anatomy, ocular anatomy and select areas of head and neck anatomy. These candidates are often then faced with the issue of accessing facilities with dissected human cadaveric material. In light of these difficulties, we developed a novel means of creating high-resolution reproductions of prosected human cadaver orbits suitable for education and training. 3D printed copies of cadaveric orbital dissections (superior, lateral and medial views) showing a range of anatomical features were created. These 3D prints offer many advantages over plastinated specimens as they are suitable for rapid reproduction and as they are not human tissue they avoid cultural and ethical issues associated with viewing cadaver specimens. In addition, they are suitable for use in the office, home, laboratory or clinical setting in any part of the world for patient and doctor education. Published by the BMJ Publishing Group Limited.

The objective of this study was to investigate the anatomy, both macroscopic and microscopic, of the soft tissue internal structures of the hip joint in animal species and in three human hips (an adult and two fetuses). We dissected the hip joints of 16 species and compared the anatomical features of the soft tissue from the respective acetabula. In addition, a histological study was made of the specimens studied. In amphibians, we found a meniscus in the acetabulum, which was not observed in any of the other species studied. The isolated round ligament is observed from birds onwards. In the group of mammals analysed, including the human specimens, we found a meniscoid structure in the acetabular hip joint. Furthermore, we found that the meniscoid structure forms an anatomo-functional unit with the round ligament and the transverse ligament of the coxofemoral joint. These discoveries suggest the participation of the soft tissue anatomy in adaptative changes of species. © 2011 Blackwell Verlag GmbH.

Teaching clinically relevant dental anatomy in the dental curriculum: description and assessment of an innovative module.

2011-06-01

The primary objective of the preclinical dental anatomy course in the predoctoral dental curriculum is to introduce students to cognitive and psychomotor skills related to the morphology and spatial and functional relationships of human dentition. Traditionally, didactic content for the subject is found in textbooks and course manuals and summarized by the faculty in lectures to the entire class. Psychomotor skills associated with recognition and reproduction of tooth morphology are traditionally learned by examining preserved tooth specimens and their cross-sections, combined with producing two-dimensional line drawings and carving teeth from wax blocks. These activities have little direct clinical application. In most cases, students are passive in the learning process, and assessment of student performance is unilateral and subjective. A recently revised dental anatomy module at the University of Illinois at Chicago College of Dentistry integrates independent class preparation with active small-group discussion and patient scenario-based wax-up exercises to replace missing tooth structure on manikin teeth. The goal of the revision is to shift emphasis away from decontextualized technical learning toward more active and clinically applicable learning that improves conceptual understanding while contributing to early acquisition of psychomotor skills. This article describes the rationale, components, and advantages of the revised module and presents a pre-post comparison of student learning outcomes for three class cohorts (N=203).

The exhibitions of plastinated cadavers and organs have attracted millions of visitors globally, while raising serious controversy about their content and purpose of implementation. We performed a survey based study on 500 randomly chosen individuals, aged 18- to 35-year old, in order to access their opinion regarding the conduction of such shows as well as body donation for scientific purposes. We found that 46.3% of the participants had moral concerns, and 46.1% did not. Religious and philosophical beliefs concerned 21.8% of the sample, while 28% believed that the exhibits may affect visitors' mental health. Human dignity violation was stressed by 21.6%, whereas 26.6% disagreed with body donation to science. The desire for qualitative-guided anatomy education is evident from the highly popular plastinated body and specimen exhibitions. Hence, additional focused effort could be provided to educate the public about normal and pathological anatomy in order to amend their life-style. This could be effected by certified anatomy demonstrators in graduated steps according to the cohort's age, education, occupation, and health status.

Simulating the decentralized processes of the human immune system in a virtual anatomy model.

Sarpe, Vladimir; Jacob, Christian

2013-01-01

Many physiological processes within the human body can be perceived and modeled as large systems of interacting particles or swarming agents. The complex processes of the human immune system prove to be challenging to capture and illustrate without proper reference to the spatial distribution of immune-related organs and systems. Our work focuses on physical aspects of immune system processes, which we implement through swarms of agents. This is our first prototype for integrating different immune processes into one comprehensive virtual physiology simulation. Using agent-based methodology and a 3-dimensional modeling and visualization environment (LINDSAY Composer), we present an agent-based simulation of the decentralized processes in the human immune system. The agents in our model - such as immune cells, viruses and cytokines - interact through simulated physics in two different, compartmentalized and decentralized 3-dimensional environments namely, (1) within the tissue and (2) inside a lymph node. While the two environments are separated and perform their computations asynchronously, an abstract form of communication is allowed in order to replicate the exchange, transportation and interaction of immune system agents between these sites. The distribution of simulated processes, that can communicate across multiple, local CPUs or through a network of machines, provides a starting point to build decentralized systems that replicate larger-scale processes within the human body, thus creating integrated simulations with other physiological systems, such as the circulatory, endocrine, or nervous system. Ultimately, this system integration across scales is our goal for the LINDSAY Virtual Human project. Our current immune system simulations extend our previous work on agent-based simulations by introducing advanced visualizations within the context of a virtual human anatomy model. We also demonstrate how to distribute a collection of connected simulations over a

Femoral morphology and femoropelvic musculoskeletal anatomy of humans and great apes: a comparative virtopsy study.

The proximal femoral morphology of fossil hominins is routinely interpreted in terms of muscular topography and associated locomotor modes. However, the detailed correspondence between hard and soft tissue structures in the proximal femoral region of extant great apes is relatively unknown, because dissection protocols typically do not comprise in-depth osteological descriptions. Here, we use computed tomography and virtopsy (virtual dissection) for non-invasive examination of the femoropelvic musculoskeletal anatomy in Pan troglodytes, P. paniscus, Gorilla gorilla, Pongo pygmaeus, and Homo sapiens. Specifically, we analyze the topographic relationship between muscle attachment sites and surface structures of the proximal femoral shaft such as the lateral spiral pilaster. Our results show that the origin of the vastus lateralis muscle is anterior to the insertion of gluteus maximus in all examined great ape specimens and humans. In gorillas and orangutans, the insertion of gluteus maximus is on the inferior (anterolateral) side of the lateral spiral pilaster. In chimpanzees, however, the maximus insertion is on its superior (posteromedial) side, similar to the situation in modern humans. These findings support the hypothesis that chimpanzees and humans exhibit a shared-derived musculoskeletal topography of the proximal femoral region, irrespective of their different locomotor modes, whereas gorillas and orangutans represent the primitive condition. Caution is thus warranted when inferring locomotor behavior from the surface topography of the proximal femur of fossil hominins, as the morphology of this region may contain a strong phyletic signal that tends to blur locomotor adaptation.

Content-Specific Auditing of a Large Scale Anatomy Ontology

Biomedical ontologies are envisioned to be useable in a range of research and clinical applications. The requirements for such uses include formal consistency, adequacy of coverage, and possibly other domain specific constraints. In this report we describe a case study that illustrates how application specific requirements may be used to identify modeling problems as well as data entry errors in ontology building and evolution. We have begun a project to use the UW Foundational Model of Anatomy (FMA) in a clinical application in radiation therapy planning. This application focuses mainly (but not exclusively) on the representation of the lymphatic system in the FMA, in order to predict the spread of tumor cells to regional metastatic sites. This application requires that the downstream relations associated with lymphatic system components must only be to other lymphatic chains or vessels, must be at the appropriate level of granularity, and that every path through the lymphatic system must terminate at one of the two well known trunks of the lymphatic system. It is possible through a programmable query interface to the FMA to write small programs that systematically audit the FMA for compliance with these constraints. We report on the design of some of these programs, and the results we obtained by applying them to the lymphatic system. The algorithms and approach are generalizable to other network organ systems in the FMA such as arteries and veins. In addition to illustrating exact constraint checking methods, this work illustrates how the details of an application may reflect back a requirement to revise the design of the ontology itself.

To evaluate the microsurgical anatomy of the fiber tract connections of the supplementary motor area (SMA) and pre-SMA, and examine its potential functional role with reference to clinical trials in the literature. Ten postmortem formalin-fixed human brains (20 sides) and 1 cadaveric head were prepared following Klingler's method. The fiber dissection was performed in a stepwise fashion, from lateral to medial and also from medial to lateral, under an operating microscope, with 3D images captured at each stage. Our findings were supported by in vivo magnetic resonance imaging tractography in 2 healthy subjects. The connections of the SMA complex, composed of the pre-SMA and the SMA proper, are composed of short "U" association fibers and the superior longitudinal fasciculus I, cingulum, claustrocortical fibers, callosal fibers, corticospinal tract, frontal aslant tract, and frontostriatal tract. The claustrocortical fibers may play an important role in the integration of motor, language, and limbic functions of the SMA complex. The frontostriatal tract connects the pre-SMA to the putamen and caudate nucleus, and also forms parts of both the internal capsule and the dorsal external capsule. The SMA complex has numerous connections throughout the cerebrum. An understanding of these connections is important for presurgical planning for lesions in the frontal lobe and helps explain symptoms related to SMA injury. Copyright © 2016 Elsevier Inc.

The success of endodontic therapy is based on good endodontic access, correct cleaning and shaping, and adequate root canal obturation. However, endodontic treatment is also dependent on a sound knowledge of the internal anatomy of human teeth, especially when anatomical variations are present. Certain anatomical changes may be present to varying degrees, and it is important to report these to improve the understanding and expertise of endodontic specialists. With this aim in mind, this study reports an example of a maxillary first molar showing unusual anatomy (four roots and six root canals) and describes the endodontic treatment that was employed.

An audience response system (ARS) has become popular among educators in medicine and the health professions because of the system's ability to engage listeners during a lecture presentation. No one has described the usefulness of ARS technology during planned nonlecture peer teaching sessions in gross anatomy instruction for health professionals. The unique feature of each peer teaching session was a nongraded 12-15 item ARS quiz assembled by six second-year doctor of physical therapy (DPT) students and purposely placed at the beginning of the review session for those first-year DPT students in attendance. This study used a ten-item questionnaire and a five-point Likert scale in addition to three open ended questions to survey perceptions of both first-year and second-year DPT students about the usefulness of ARS technology implemented during weekly interactive peer teaching sessions during a semester course in Anatomy for Physical Therapists. First-year students overwhelmingly acknowledged the ARS system permitted each student to self-assess his/her preparedness for a quiz or examination and compare his/her performance with that of classmates. Peer teachers recognized an ARS quiz provided them an opportunity to: (1) estimate first-year students' level of understanding of anatomical concepts; and (2) effectively prepare first-year students for their weekly quizzes and future examinations. On the basis of the mutual benefits derived by both students/tutees and teachers/tutors, physical therapist educators may wish to consider using ARS technology to enhance teaching methods for a class in gross human anatomy.

In 2004, the University of Michigan Medical School reduced its gross anatomy curriculum. To determine the effect of this reduction on resident perceptions of their clinical preparedness, we surveyed alumni that included residents from the original and new shortened curricula. A Likert-scale survey was sent to four classes of alumni. Respondents were compared in old curriculum (OC) and new curriculum (NC) groups, surgical specialty (SS) and nonsurgical specialty (NS) groups, and subgroups of SS and NS were compared for differences between OC and NC. Mean response scores were compared using independent samples T-tests. As a single population (n = 110), respondents felt their anatomy education prepared them well for residency, that a more robust anatomy curriculum would be helpful, that dissection was important to their residency preparation, and that a 4th year anatomy elective was effective in expanding their anatomy education and preparing them for residency. No significant difference existed between OC and NC groups, neither as a whole nor as SS and NS subgroups. The SS group felt dissection was more important to their residency preparation than the NS group (P = 0.001) and that a more robust anatomy curriculum would have better prepared them for residency (P = 0.001). Thirty percent of SS respondents who did not take a 4th year elective commented that they wish they had. Fourth year anatomy electives were highly valued by residents, and respondents felt that they should be offered to students as a way of revisiting anatomy following the 1st year of clinical training.

Influence of environmental stress factors on both crop and wild plants of nutritional value is an important research topic. The past research has focused on rising temperatures, drought, soil salinity and toxicity, but the potential effects of increased environmental contamination by human-generated electromagnetic radiation on plants have little been studied. Here we studied the influence of microwave irradiation at bands corresponding to wireless router (WLAN) and mobile devices (GSM) on leaf anatomy, essential oil content and volatile emissions in Petroselinum crispum, Apium graveolens and Anethum graveolens. Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles (GLV). These effects were stronger for WLAN-frequency microwaves. Essential oil content was enhanced by GSM-frequency microwaves, but the effect of WLAN-frequency microwaves was inhibitory. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied. These data collectively demonstrate that human-generated microwave pollution can potentially constitute a stress to the plants. Copyright © 2014 Elsevier GmbH. All rights reserved.

Knowing the types and frequency of adrenal vein variants would help surgeons identify and control the adrenal vein during laparoscopic adrenalectomy. To establish the surgical anatomy of the main vein and its variants for laparoscopic adrenalectomy and to analyze the relationship between variant adrenal venous anatomy and tumor size, pathologic diagnosis, and operative outcomes. In a retrospective review of patients at a tertiary referral hospital, 506 patients underwent 546 consecutive laparoscopic adrenalectomies between April 22, 1993, and October 21, 2011. Patients with variant adrenal venous anatomy were compared with patients with normal adrenal venous anatomy regarding preoperative variables (patient and tumor characteristics [size and location] and clinical diagnosis), intraoperative variables (details on the main adrenal venous drainage, any variant venous anatomy, duration of operation, rate of conversion to hand-assisted or open procedure, and estimated blood loss), and postoperative variables (transfusion requirement, reoperation for bleeding, duration of hospital stay, and histologic diagnosis). Laparoscopic adrenalectomy. Prevalence of variant adrenal venous anatomy and its relationship to tumor characteristics, pathologic diagnosis, and operative outcomes. Variant venous anatomy was encountered in 70 of 546 adrenalectomies (13%). Variants included no main adrenal vein identifiable (n = 18), 1 main adrenal vein with additional small veins (n = 11), 2 adrenal veins (n = 20), more than 2 adrenal veins (n = 14), and variants of the adrenal vein drainage to the inferior vena cava and hepatic vein or of the inferior phrenic vein (n = 7). Variants occurred more often on the right side than on the left side (42 of 250 glands [17%] vs. 28 of 296 glands [9%], respectively; P = .02). Patients with variant anatomy compared with those with normal anatomy had larger tumors (mean, 5.1 vs 3.3 cm, respectively; P < .001), more pheochromocytomas (24 of 70 [35%] vs

The purpose of this investigation was to determine the influence of colored shade nets on the growth, anatomy and essential oil content, yield and chemical composition of Pogostemon cablin. The plants were cultivated under full sunlight, black, blue and red nets. The harvesting was performed 5 months after planting and it was followed by the analysis of plant growth parameters, leaf anatomy, essential oil content, yield and chemical composition. The plants grown under red net have produced more leaf, shoot, total dry weight and leaf area. Plants cultivated under colored nets showed differences in morphological features. Plants maintained under red net had a higher leaf blade thickness and polar and equatorial diameter of the stomata ratio. Additionally, higher yield of essential oil in the leaves was observed under red and blue colored shade net. The essential oil of the plants grown under red net showed the highest relative percentage of patchoulol (66.84%). Therefore, it is possible using colored shade nets to manipulate P. cablin growth, as well as its essential oil production with several chemical compositions. The analyses of principal components allowed observing that pogostol has negative correlation with α-guaiene and α-bulnesene. There was difference in total dry weight and patchoulol content when the patchouli is cultured under the red colored shade nets.

Because medical students have many different learning styles, the authors, medical students at Mayo Clinic, College of Medicine researched the history of anatomical specimen procurement, reviewing topic-related film, academic literature, and novels, to write, direct, and perform a dramatization based on Robert Louis Stevenson's The Body-Snatcher. Into this performance, they incorporated dance, painting, instrumental and vocal performance, and creative writing. In preparation for the performance, each actor researched an aspect of the history of anatomy. These micro-research projects were presented in a lecture before the play. Not intended to be a research study, this descriptive article discusses how student research and ethics discussions became a theatrical production. This addition to classroom and laboratory learning addresses the deep emotional response experienced by some students and provides an avenue to understand and express these feelings. This enhanced multimodal approach to"holistic learning" could be applied to any topic in the medical school curriculum, thoroughly adding to the didactics with history, humanities, and team dynamics.

Embryology and anatomy of the vulva: the female orgasm and women's sexual health.

PubMed

Puppo, Vincenzo

2011-01-01

Sexual health is vital to overall well-being. Orgasm is a normal psycho-physiological function of human beings and every woman has the right to feel sexual pleasure. The anatomy of the vulva and of the female erectile organs (trigger of orgasm) is described in human anatomy textbooks. Female sexual physiology was first described in Dickinson's textbook in 1949 and subsequently by Masters and Johnson in 1966. During women's sexual response, changes occur in the congestive structures that are essential to the understanding of women's sexual response and specifically of their orgasm. Female and male external genital organs arise from the same embryologic structures, i.e. phallus, urogenital folds, urogenital sinus and labioscrotal swellings. The vulva is formed by the labia majora and vestibule, with its erectile apparatus: clitoris (glans, body, crura), labia minora, vestibular bulbs and corpus spongiosum. Grafenberg, in 1950, discovered no "G-spot" and did not report an orgasm of the intraurethral glands. The hypothetical area named "G-spot" should not be defined with Grafenberg's name. The female orgasm should be a normal phase of the sexual response cycle, which is possible to achieve by all healthy women with effective sexual stimulation. Knowledge of the embryology, anatomy and physiology of the female erectile organs are important in the field of women's sexual health. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Primary ciliary dyskinesia (PCD) is a respiratory syndrome in which 'random' organ orientation can occur; with approximately 46% of patients developing situs inversus totalis at organogenesis. The aim of this study was to explore the relationship between organ anatomy and curve convexity by studying the prevalence and convexity of idiopathic scoliosis in PCD patients with and without situs inversus. Chest radiographs of PCD patients were systematically screened for existence of significant lateral spinal deviation using the Cobb angle. Positive values represented right-sided convexity. Curve convexity and Cobb angles were compared between PCD patients with situs inversus and normal anatomy. A total of 198 PCD patients were screened. The prevalence of scoliosis (Cobb >10°) and significant spinal asymmetry (Cobb 5-10°) was 8 and 23%, respectively. Curve convexity and Cobb angle were significantly different within both groups between situs inversus patients and patients with normal anatomy (P ≤ 0.009). Moreover, curve convexity correlated significantly with organ orientation (P < 0.001; ϕ = 0.882): In 16 PCD patients with scoliosis (8 situs inversus and 8 normal anatomy), except for one case, matching of curve convexity and orientation of organ anatomy was observed: convexity of the curve was opposite to organ orientation. This study supports our hypothesis on the correlation between organ anatomy and curve convexity in scoliosis: the convexity of the thoracic curve is predominantly to the right in PCD patients that were 'randomized' to normal organ anatomy and to the left in patients with situs inversus totalis.

Constancy and characteristics of the anterior cutaneous branch of the first intercostal nerve: correcting the descriptions in human anatomy texts.

Miyawaki, Makoto

2006-12-01

Human anatomy texts state that the anterior cutaneous branch of the first intercostal nerve (Rca-Th1) does not exist or that, even if it does, it is poorly developed. However, an anterior cutaneous branch in the first intercostal space (Rca-1) was observed in 74.8% of cases examined (104/139 sides) and was not poorly developed at all. Some of the observed Rca-I were even larger than the anterior cutaneous branches in the second intercostal space (Rca-ll). The segment of origin of the Rca-I was analyzed in 37 sides and 66.2% (49/74 branches) were confirmed to be from Th1. As a result, in contrast with traditional beliefs, it was shown that Rca-Th1 exists. The Rca-I was classified into two types according to the course and distribution: (i) an anterior cutaneous branch that appeared at the anterior end of the first intercostal space (ICS), ran through the pectoralis major muscle and extended in the first ICS (Rca-1); and (ii) another branch that appeared at the same place but ran downward along the anterior surface of the second costal cartilage, deep to the pectoralis major muscle, to reach the inferior edge of the second costal cartilage or the second ICS, passed through the pectoralis major muscle and extended to the second rib or the second ICS (pseudo Rca-2). It was found that 77.8% (35/45 branches) of Rca-1 and 48.3% (14/29 branches) of pseudo Rca-2 were derived from Th1. Accordingly, the author suggests that the description in human anatomy texts should be revised to read, '... the Rca-Th1 exists quite constantly and some of appear at a position resembling Rca-Th2'.

The development of multimedia content aims to answer the problems experienced by the research team and other researchers who will conduct similar research. The method used in the development of multimedia content as facial expression datasets for human emotion recognition is the Villamil-Molina version of the multimedia development method. Multimedia content developed with 10 subjects or talents with each talent performing 3 shots with each capturing talent having to demonstrate 19 facial expressions. After the process of editing and rendering, tests are carried out with the conclusion that the multimedia content can be used as a facial expression dataset for recognition of human emotions.

The femoral enthesis of the human anterior cruciate ligament (ACL) is known to be more susceptible to injury than the tibial enthesis. To determine whether anatomic differences might help explain this difference, we quantified the microscopic appearance of both entheses in 15 unembalmed knee specimens using light microscopy, toluidine blue stain and image analysis. The amount of calcified fibrocartilage and uncalcified fibrocartilage, and the ligament entheseal attachment angle were then compared between the femoral and tibial entheses via linear mixed-effects models. The results showed marked differences in anatomy between the two entheses. The femoral enthesis exhibited a 3.9-fold more acute ligament attachment angle than the tibial enthesis (p<0.001), a 43% greater calcified fibrocartilage tissue area (p<0.001), and a 226% greater uncalcified fibrocartilage depth (p<0.001), with the latter differences being particularly pronounced in the central region. We conclude that the ACL femoral enthesis has more fibrocartilage and a more acute ligament attachment angle than the tibial enthesis, which provides insight into why it is more vulnerable to failure. © 2015 Orthopaedic Research Society.

The 'morbid anatomy' of the human genome: tracing the observational and representational approaches of postwar genetics and biomedicine the William Bynum Prize Essay.

PubMed

Hogan, Andrew J

2014-07-01

This paper explores evolving conceptions and depictions of the human genome among human and medical geneticists during the postwar period. Historians of science and medicine have shown significant interest in the use of informational approaches in postwar genetics, which treat the genome as an expansive digital data set composed of three billion DNA nucleotides. Since the 1950s, however, geneticists have largely interacted with the human genome at the microscopically visible level of chromosomes. Mindful of this, I examine the observational and representational approaches of postwar human and medical genetics. During the 1970s and 1980s, the genome increasingly came to be understood as, at once, a discrete part of the human anatomy and a standardised scientific object. This paper explores the role of influential medical geneticists in recasting the human genome as being a visible, tangible, and legible entity, which was highly relevant to traditional medical thinking and practice. I demonstrate how the human genome was established as an object amenable to laboratory and clinical research, and argue that the observational and representational approaches of postwar medical genetics reflect, more broadly, the interdisciplinary efforts underlying the development of contemporary biomedicine.

To examine the impact that anatomy-focused radiology teaching has on non-examined knowledge regarding radiation safety and radiology as a specialty. First-year undergraduate medical students completed surveys prior to and after undertaking the first-year anatomy programme that incorporates radiological anatomy. Students were asked opinions on preferred learning methodology and tested on understanding of radiology as a specialty and radiation safety. Pre-module and post-module response rates were 93 % (157/168) and 85 % (136/160), respectively. Pre-module and post-module, self-directed learning (SDL) ranked eighth (of 11) for preferred gross-anatomy teaching formats. Correct responses regarding radiologist/radiographer roles varied from 28-94 % on 16 questions with 4/16 significantly improving post-module. Identification of modalities that utilise radiation significantly improved for five of eight modalities post-module but knowledge regarding relative amount of modality-specific radiation use was variable pre-module and post-module. SDL is not favoured as an anatomy teaching method. Exposure of students to a radiological anatomy module delivered by senior clinical radiologists improved basic knowledge regarding ionising radiation use, but there was no improvement in knowledge regarding radiation exposure relative per modality. A possible explanation is that students recall knowledge imparted in didactic lectures but do little reading around the subject when the content is not examined. • Self-directed learning is not favoured as a gross anatomy teaching format amongst medical students. • An imaging anatomy-focused module improved basic knowledge regarding ionising radiation use. • Detailed knowledge of modality-specific radiation exposure remained suboptimal post-module. • Knowledge of roles within a clinical radiology department showed little change post-module.

This study examined the impact of iPad integration on performance in an undergraduate gross anatomy course. Two out of six course sections were assigned to one of the following conditions: control (no iPad, n = 61); limited access (laboratory iPads, n = 58); and unlimited access (personal iPads, n = 47). Student knowledge was assessed over time during the semester with two practical examinations in laboratory and four multiple choice/essay examinations in lecture. The same PowerPoint presentations and examinations were utilized for all conditions. Mixed ANOVA analysis identified an interaction effect between time and condition for both laboratory (F2,153  = 16.12; P < 0.05) and lecture (F6,462  = 5.47; P < 0.05) performance. Between laboratory examinations, student performance was lower by 4.2% and higher by 3.0% in control and unlimited access conditions, respectively. Unlimited access students scored higher than control and limited access (82.8 ± 2.2 vs 71.5 ± 2.6 and 74.3 ± 1.7%; P < 0.05) and higher than control students (78.7 ± 2.1 vs 70.6 ± 2.0%; P < 0.05) on the third and fourth lecture examination, respectively. Postsemester surveys completed by experimental students (89.5% response rate) indicated that a greater percentage of unlimited vs limited access students agreed that laboratory (84.8 vs 56.3%, P < 0.05) and lecture (58.7 vs 14.6%, P < 0.05) performance was enhanced with the iPad. Results suggest that if students are given the opportunity to overcome the technology learning curve, tablet devices and relevant applications can be useful tools in human anatomy courses.

Anatomy: a must for teaching the next generation.

Older, J

2004-04-01

Teaching anatomy to both undergraduate medical students and medical graduates is in the midst of a downward spiral. The traditional anatomy education based on topographical structural anatomy taught by didactic lectures and complete dissection of the body with personal tuition, has been replaced by a multiple range of special study modules, problem-based workshops, computers, plastic models and many other teaching tools. In some centres, dissected cadaver-based anatomy is no longer taught. Changing the undergraduate medical curriculum in the UK has taken place without any research into the key aspects of knowledge necessary or comparing methods of teaching. There is no agreement on a common national core curriculum and as a result, numerous new curricula have been introduced. No external audit or validation is carried out, so medical schools have been free to teach and assess their own work themselves. There is a great divergence in medical schools across the UK and Ireland in teaching medicine in general and anatomy in particular. Published data on the impact of these changes is scant. The reduction in undergraduate teaching and knowledge of anatomy has caused great concern, not only for undergraduates but also to postgraduate students, especially in surgery. This, together with a change in basic surgical training, a marked reduction in demonstrator posts and a change in examination standards, has set up a system that is allowing young men and women with a poor knowledge of anatomy to become surgeons. There should be a full public debate at every level; the Royal Colleges, specialist associations, the Universities, Government, both health and education. This debate should highlight areas of concern, explore in depth and define a minimal core curriculum for anatomy. Teaching must be enhanced with a critical look at both teachers and methods. The dominance of research must be reassessed to establish an equitable cohabitation with teaching. The place of basic science

Three-dimensional (3D) printing is a modern technique of creating 3D-printed models that allows reproduction of human structures from MRI and CT scans via fusion of multiple layers of resin materials. To assess feasibility of this innovative resource as anatomy educational tool, we conducted a preliminary study on Curtin University undergraduate students to investigate the use of 3D models for anatomy learning as a main goal, to assess the effectiveness of different specimen types during the sessions and personally preferred anatomy learning tools among students as secondary aim. The study consisted of a pre-test, exposure to test (anatomical test) and post-test survey. During pre-test, all participants (both without prior experience and experienced groups) were given a brief introduction on laboratory safety and study procedure thus participants were exposed to 3D, wet and plastinated specimens of the heart, shoulder and thigh to identify the pinned structures (anatomical test). Then, participants were provided a post-test survey containing five questions. In total, 23 participants completed the anatomical test and post-test survey. A larger number of participants (85%) achieved right answers for 3D models compared to wet and plastinated materials, 74% of population selected 3D models as the most usable tool for identification of pinned structures and 45% chose 3D models as their preferred method of anatomy learning. This preliminary small-size study affirms the feasibility of 3D-printed models as a valuable asset in anatomy learning and shows their capability to be used adjacent to cadaveric materials and other widely used tools in anatomy education.

Students commence nurse education with varying levels of understanding of human anatomy and physiology due to a wide range of previous exposure to the topic. All students, however, are required to attain a broad knowledge of this topic prior to qualification. This paper describes the use of a Virtual Learning Environment (VLE), Blackboard 5, and the associated development of appropriate resources aimed at supporting nursing students undertaking a human anatomy and physiology module at Higher Education Level 1. The VLE was used as part of a blended learning approach. The results suggested that the majority of students utilised the VLE throughout the academic year. Opportunities for independent and self-directed learning were available in that students chose when and where to learn. Students generally commented favourably on ease of use and type of resources available. Frequency of use of the VLE, however, did not correlate strongly with the final examination mark achieved. Overall the VLE and the associated available resources appeared useful in supporting student learning and has been adopted for use in subsequent years.

Over the past century, medical imaging has brought a new revolution: internal anatomy of a patient could be seen without any invasive technique. This revolution has highlighted the two main limits of current anatomy: the anatomical description is physician dependent, and the average anatomy is more and more frequently insufficient to describe anatomical variations. These drawbacks can sometimes be so important that they create mistakes but they can be overcome through the use of 3D patient-specific surgical anatomy. In this article, we propose to illustrate such improvement of standard anatomy on liver. We first propose a general scheme allowing to easily compare the four main liver anatomical descriptions by Takasaki, Goldsmith and Woodburne, Bismuth and Couinaud. From this general scheme we propose four rules to apply in order to correct these initial anatomical definitions. Application of these rules allows to correct usual vascular topological mistakes of standard anatomy. We finally validate such correction on a database of 20 clinical cases compared to the 111 clinical cases of a Couinaud article. Out of the 20 images of the database, we note a revealing difference in 14 cases (70%) on at least one important branch of the portal network. Only six cases (30%) do not present a revealing difference between both labellings. We also show that the right portal fissure location on our 20 cases defined between segment V and VI of our anatomical definition is well correlated with the real position described by Couinaud on 111 cases, knowing that the theoretical position was only found in 46 cases out of 111, i.e., 41.44% of cases with the non-corrected Couinaud definition. We have proposed a new anatomical segmentation of the liver based on four main rules to apply in order to correct topological errors of the four main standard segmentations. Our validation clearly illustrates that this new definition corrects the large amount of mistakes created by the current

Research in microneurosurgical anatomy has contributed to great advances in neurosurgery in the last 40 years. Many Japanese neurosurgeons have traveled abroad to study microsurgical anatomy and played major roles in advancing and spreading the knowledge of anatomy, overcoming their disadvantage that the cadaver study has been strictly limited inside Japan. In Japan, they initiated an educational system for surgical anatomy that has contributed to the development and standardization of Japanese neurosurgery. For example, the Japanese Society for Microsurgical Anatomy started an annual educational meeting in the middle of 1980s and published its proceedings in Japanese every year for approximately 20 years. These are some of the achievements that bring worldwide credit to Japanese neurosurgeons. Not only should Japanese neurosurgeons improve their educational system but they should also contribute to the international education in this field, particularly in Asia. PMID:25797782

One of the strong trends in medical education today is the integration of the humanities into the basic medical curriculum. The anatomy program is an obvious choice for using the humanities to develop professionalism and ethical values. They can also be used to develop close observational skills. Many medical schools have developed formal art observation training in conjunction with nearby art museums to enhance the visual diagnostic skills of their medical students. We report here on an art and anatomy workshop that paired medical and art students who did drawing exercises from plastinated anatomical specimens and the animated face to hone observational skills. Each member of the pair brought a different perspective and expertise to the work that allowed each to be a mentor to the other. The workshop had three sessions: the first involved drawings of plastinated specimens that allowed an intimate experience with authentic human material; the second involved drawings of the human face; and the third included examination of anatomical texts of important anatomist-artists, a lecture on contemporary artists whose work involves anatomy, and a film demonstrating the facial muscles. We propose workshops such as these will help students increase their ability to detect details. This will assist the medical student in developing diagnostic skills for identifying disease and the art student in using the human body as subject. We further propose that these programs will help students develop humanistic sensitivities and provide an outlet for expression of the emotional aspects of dealing with disease and mortality.

The aim of this study was to investigate the pancreas anatomy and surgical procedure for harvesting pancreas for islet isolation while performing pancreatectomy to induce diabetes in rhesus monkeys. The necropsy was performed in three cadaveric monkeys. Two monkeys underwent the total pancreatectomy and four underwent partial pancreatectomy (70-75%). The greater omentum without ligament to transverse colon, the cystic artery arising from the proper hepatic artery and the branches supplying the paries posterior gastricus from the splenic artery were observed. For pancreatectomy, resected pancreas can be used for islet isolation. Diabetes was not induced in the monkeys undergoing partial pancreatectomy (70-75%). Pancreas anatomy in rhesus monkeys is not the same as in human. Diabetes can be induced in rhesus monkeys by total but not partial pancreatectomy (70-75%). Resected pancreas can be used for islet isolation while performing pancreatectomy to induce diabetes. © 2011 John Wiley & Sons A/S.

Chromium has many important functions in the human body. For the osseous tissue, its role has not been clearly defined. This study was aimed at determining chromium content in hip joint tissues. A total of 91 hip joint samples were taken in this study, including 66 from females and 25 from males. The sample tissues were separated according to their anatomical parts. The chromium content was determined by the AAS method. The statistical analysis was performed with U Mann-Whitney's non-parametric test, P≤0.05. The overall chromium content in tissues of the hip joint in the study subjects was as follows: 5.73 µg/g in the articular cartilage, 5.33 µg/g in the cortical bone, 17.86 µg/g in the cancellous bone, 5.95 µg/g in the fragment of the cancellous bone from the intertrochanteric region, and 1.28 µg/g in the joint capsule. The chromium contents were observed in 2 group patients, it was 7.04 µg/g in people with osteoarthritis and 12.59 µg/g in people with fractures. The observed chromium content was highest in the cancellous bone and the lowest in the joint capsule. Chromium content was significantly different between the people with hip joint osteoarthritis and the people with femoral neck fractures.

We report the development of a novel otoscopy probe for assessing middle ear anatomy and function. Video imaging and phase-sensitive optical coherence tomography are combined within the same optical path. A sound stimuli channel is incorporated as well to study middle ear function. Thus, besides visualizing the morphology of the middle ear, the vibration amplitude and frequency of the eardrum and ossicles are retrieved as well. Preliminary testing on cadaveric human temporal bone models has demonstrated the capability of this instrument for retrieving middle ear anatomy with micron scale resolution, as well as the vibration of the tympanic membrane and ossicles with sub-nm resolution.

Tissues for the study were obtained intraoperatively during hip replacement procedures from 96 patients. In all the cases, the indication for this treatment was primary or secondary degenerative changes in the hip joint. The subject of the study was the head and neck of the femur, resected in situ. Aluminium concentrations measured in femoral head and neck samples from patients aged between 25 and 91 were varied. Statistical methods were applied to determine the variations in relation to the parameters from the background survey. Significant differences in the aluminium content of femoral head samples were observed between patients under and over 60 years of age. Based on the results, it was confirmed that the aluminium accumulates in bones over a lifetime. The study showed that the content of aluminium in the head and neck of the femur depends on the factors such as: type of medicines taken, contact with chemicals at work, differences in body anatomy and sex. The study on the levels of aluminium in bones and the factors affecting its concentration is a valuable source of information for further research on the role of aluminium in bone diseases. Based on the investigations, it was found that the GF-AAS technique is the best analytical tool for routine analysis of aluminium in complex matrix samples. The use of femoral heads in the investigations was approved by the Bioethics Committee of the University of Medical Sciences in Poznań (Poland). Copyright © 2015 Elsevier Inc. All rights reserved.
