Use of Web-based materials to enhance anatomy instruction in the health sciences

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.     

Provision of anatomical teaching in a new British medical school: getting the right mix

In response to a government report, which recommended a substantial increase in the number of medical students in the United Kingdom by 2005, several new medical schools have been set up throughout the country. One such school, the Brighton and Sussex Medical School (BSMS), recently opened its doors to new students. BSMS offers a 5-year medical curriculum that uses an integrated systems-based approach to cultivate academic knowledge and clinical experience. Anatomy is one of the core elements of the program and, as such, features strongly within the modular curriculum. The challenge for the anatomy faculty has been to decide how best to integrate anatomy into the new curriculum and what teaching modalities should be used. A multidisciplinary approach has been taken using both traditional and contemporary teaching methods. Unlike most of the other new medical schools, BSMS uses cadaveric dissection as the cornerstone of its teaching, as the faculty believes that dissection still provides the most powerful technique for demonstrating anatomy as well as enhancing communication and teamwork skills. The dissection experience is handled using an understanding and professional way. However, to ensure that our students do not become detached from the process of patient-focused care, emphasis in the dissecting room environment is also placed on respect and compassion. To enhance conceptual understanding of structure and function and provide further clinical relevance, we are using imaging technology to demonstrate living anatomy. Unique to the BSMS curriculum is the teaching of the anatomy in the later years of the program. During specialist rotations, students will return to the dissecting room to study the anatomy relevant to that area. Such vertical integration ensures that core anatomical knowledge is gained at the most appropriate level relative to a student's clinical experience.     

Quidne mortui vivos docent? The evolving purpose of human dissection in medical education.

The dissection experience has evolved over the past 500 years, following broader cutural trends in science and medicine. Through this time each period has recruited human gross anatomic dissection for characteristic purposes. Key variables have been: (1) the motivating philosophies of medicine and science, (2) how well clinical medicine and basic science have been integrated by anatomy, and (3) how explicity thoughts or feelings about death and dying have been addressed in the context of anatomy. The authors are especially interested in the third variable, and suggest that although anatomy is scientifically in decline, dissection is currently enjoying a revival as a vehicle for teaching humanist values in medical school. Changes in the culture of medicine have carried anatomy from a research science, to a training tool, nearly to a hazing ritual, to a vehicle for ethical and moral education. Physicians, scientists, and medical students, as well as observers such as sociologists and writers, have been only intermittently aware of these cultural shifts. Yet anatomic dissection has been remarkably persistent as a feature of medical education-indeed it stands out as the most universal and universally recognizable step in becoming a doctor. This paper attempts to explore and interpret in detail the history of anatomy education, drawing on both subjective commentary and objective data from each period.     

Human anatomy: A foundation for education about death and dying in medicine

In most medical schools, little curricular time is devoted to the art of medicine, and this is particularly evident with respect to death education. We make a case for including education on death and dying in medical schools, specifically its early introduction in the anatomy course. Studies indicate that whereas dissection of cadavers is an exciting discovery for most students, for many it is traumatic and if not addressed, students may use depersonalization and denial as their approach to suffering. The dissecting experiences in two different medical schools are described. The University of Massachusetts program developed in a traditional curriculum and explores humanistic issues with lectures and group discussions. Parallels are drawn between dissection and patient care, and coping styles are discussed openly. In the problem-based curriculum at Dalhousie Medical School, death and grief are discussed in the first week of medical school, and students are given information about the body donor program and support systems for students. This program is part of a longitudinal curriculum on death and dying. In both schools, students tour the dissecting rooms before the course begins and organize memorial events for body donors at the end of the academic year. These examples illustrate how death education can begin early in the medical curriculum and contribute to the development of practitioners who are sensitive to broader issues of human mortality.

Overcoming the tension between scientific and religious views in teaching anatomical dissection: the Israeli experience

More than three thousand years of Jewish historical and scholarly writings have addressed the problematic relationship between anatomical dissection for the purpose of medical education and Judaism, which values the wholeness and sanctity of the human body. The Department of Anatomy at Tel Aviv University's Sackler Faculty of Medicine has sought to bridge the gap between science and Jewish religious-cultural values. The Department requires students to conduct laboratory dissections on cadavers in an ethical and respectful manner. Student emotions are also addressed by the Department as students are encouraged to share their apprehensions and concerns about participating in dissections in discussion groups. At the same time, the high academic standards of the medical school are strictly upheld, ensuring that each student has a thorough knowledge of human anatomy. Teaching anatomy in Israeli medical school involves reconciling two conflicting approaches to dissection: (1) The scientific-medical approach, which views the human body as inert material and anatomical dissection as a means of studying anatomy and gaining medical knowledge. (2) A Jewish religious point of view, which perceives anatomical dissection as a threat to the sanctity of a human body and leads to the defilement of those participating in the dissection. In this article, the views of major Jewish scholars regarding dissection are presented and discussed in relation to their implementation in the dissection theater. These views are examined in an anthropological light based on observations in the dissection room and interviews with students and faculty members. The findings reflect the emotions and concerns of Israeli medical students at the Sackler Faculty of Medicine in particular as well as those of the Israeli-Jewish population as a whole. In the dissection theater, medical students must gain a comprehensive understanding of human anatomy while dealing with their own personal ethical, cultural, and religious views on death and dying. Confronting these issues enhances both personal growth as individuals and professional behavior as future physicians.     

Human gross anatomy: A crucial time to encourage respect and compassion in students

We suggest four ways in which human gross anatomy instructors can reinforce respect and compassion in students. First, encourage respectful language in the laboratory. The term “donor” should be used instead of “cadaver” or “corpse” in referring to the donated body because this promotes appreciation for the students' first “patient.” Second, provide the students with the actual name, age, history, and likely cause of death of the donor so that they more fully appreciate the donor as having once been a living human being. Third, prompt students to explore feelings and discuss topics stimulated by the intense experience of human dissection. Suggested topics include the students' feelings about dissecting a human being, the difficulty in deciding to donate one's body, the central importance of anatomy to a medical practitioner's role, and the historical development of the study of anatomy. Fourth, hold a memorial ceremony, in which both students and faculty participate, as a positive closure to an emotionally and intellectually intense course. Additionally, a ceremony reinforces salutary values in students, enhances social bonding among students, and encourages their appreciation of various cultural and religious beliefs. These methods introduce a new dimension of experience for anatomy students. We have developed these methods in response to what we view as a negative trend in the medical profession in which health care becomes technical and patients become objects. It is our role as faculty to reinforce respectful and compassionate attitudes in medical students from the very beginning. © 1995 WiIey-Liss, Inc.     

Teaching anatomy with surgeons' tools: use of the laparoscope in clinical anatomy.

The purpose of this study was to establish the feasibility of laparoscopy in embalmed cadavers to teach abdominal gross anatomy. One cadaver was selected based on body habitus and absence of previous abdominal operations. A standard trocar was used to enter the abdomen at the umbilicus. Two trocars were placed in the left upper quadrant. Pneumoperitoneum was achieved with continuous CO(2) pressure. Liver retraction was achieved percutaneously, exposing the porta hepatis and the gallbladder. The dissection was done with four first-year medical students using standard laparoscopic equipment. Following this, the demonstration was projected over multiple monitors so that all students could participate. Laparoscopic dissection in an embalmed cadaver is feasible and an excellent educational tool for both the medical student and the dissector. The dissector has the opportunity to manipulate laparoscopic tools in a human model closely paralleling operative experience, and the students have an opportunity to learn abdominal anatomy from a clinical perspective. Laparoscopic examination and dissection of fresh cadavers has been used for training surgeons on new procedures such as colon resection, antireflux procedures, and cholecystectomy. There is no report of this same technology used in embalmed cadavers to teach basic anatomy. This approach allows first-year medical students to learn the anatomy while exposing them to the technology currently used in surgical practice, and it affords surgical residents and students additional opportunities to practice laparoscopic skills.     

Workshop in clinical anatomy for residents in gynecology and obstetrics

A workshop in the clinical anatomy of the female pelvic viscera has been part of the training program for the first year residents in Gynecology and Obstetrics at the University of Padova since the 1999-2000 academic year. The purpose of the workshop is to offer a direct experience of practical anatomy despite a shortage of cadavers. It is designed for six residents who work in three teams on three specimens. The anatomical specimens are unembalmed, unfixed, female pelvic visceral blocs that are harvested from the cadavers 24 hr after death. They are stored at -12 degrees C and removed from the freezer 12 hr before the workshop. The workshop is 3 hr in length and has two parts: one on theory and one practical. In the theoretical section (30 min), the teacher presents the topographical anatomy of the specimens and the residents analyze a clinically oriented worksheet. In the practical section (2 hr), the residents identify viscera, vessels, and nerves through inspection and palpation, and then a step-by-step dissection is carried out. In the last section (30 min), the workshop includes presentations on the three specimens that illustrate anatomical variability and assess knowledge of topographical anatomy. For many residents, this is the first practical experience of the anatomy of the female pelvic viscera because the anatomical courses for medical students do not include direct dissection by students. The unfixed viscera preserves the natural characteristics of the different tissues that exhibit the aspects of living organs, such as color, softness, and pliability, enhancing the knowledge of anatomy. The worksheet is structured as a guide to the anatomical basis of physical examination through inspection and palpation of the viscera. It also introduces the residents to the surgical anatomy of the female pelvis through a brief and selective dissection focused on the relationship between the different regional systems.     

Student responses to the gross anatomy laboratory in a medical curriculum

Working with cadavers, whether through active dissection or by examination of prosected specimens, constitutes a potential stressor in medical education although there is no consensus on its effect. Some reports have suggested that it creates such a strongly negative experience that it warrants special curricular attention. To assess the issue for ourselves, we administered surveys to the freshman medical students taking the Anatomical Sciences course in the problem-based Alternative Curriculum (A.C.) at Rush Medical College for four consecutive years. We found that although a vast majority of students expressed a positive attitude toward the experience, both before and after taking the course, there remains a small percentage of students for whom human dissection may initially be a traumatic experience. We offer explanations for our findings, comments on disparate results from other studies and suggestions for appropriate responses by anatomy faculty, who must address these student needs.     

Reactions of first-year medical students to their initial encounter with a cadaver in the dissecting room

This study reports the results of a 1986 questionnaire survey of 100 first-year medical students regarding their preparation for and reactions to their first encounter with a human cadaver in the dissecting room. The students were aware of psychological and physical reactions to this experience, and although they felt adequately prepared prior to the class, expressed a desire for greater preparation afterwards, particularly through more discussion of the experience with the anatomy staff. A surprising number of the students (62) had had prior exposure to a dead human body, which was a significant influence upon their reactions. The results of this study suggest a need for improving both the preparation for coping with dissection and the follow-up opportunities for dealing with professional and emotional issues raised during human dissection.     

The evolving ethics of anatomy: Dissecting an unethical past in order to prepare for a future of ethical anatomical practice

Anatomical practice has arguably one of the most ethically challenging histories in the medical sciences. Among the oldest scientific disciplines in medicine, dissection of the human body for scientific purposes occurred as early as the third century Before the Common Era. Throughout the history of anatomical practice, human dissection has occurred in ways that cross the line from progressing medical science to violating the sanctity of the human body. The dissection of the human body creates ethical dilemmas which stem from the need for anatomical science to gain medical knowledge in juxtaposition with prevailing religious and moral views surrounding anatomy as a threat to the sanctity of the human body. This article examines the unethical history of human dissection throughout the ages and explores the rationale behind the unethical practices. In addition, this article explores imperative modern day ethical standards in anatomy including, the ethical handling of human bodies, respecting human life, and ensuring informed consent for dissection of bodies that are donated. Finally, this article explores the question of which ethical prism we should use when dealing with anatomy collections or works of the past. Learning both the history of unethical practices in anatomy and the rationale behind them is imperative so that the discipline can prepare for an ethical, diverse, and inclusive future. This article provides a foundation for understanding the evolution of ethics in anatomical practice and is a valuable resource for students and anatomists alike.     

Orientation to dissection: Assisting students through the transition

Human dissection continues to be strongly argued for teaching human anatomy to medical students and is technically and emotionally demanding. An orientation to dissection and the laboratory are provided for students before beginning their work because students' and families' reactions to dissection are often complex. This study explored medical students' experiences of attending an orientation to human dissection and the anatomy laboratory. Students' reactions, feelings, and thoughts were enquired about 1 year after beginning dissection at the University of Auckland, New Zealand. Qualitative research methods, specifically one-on-one semistructured interview were utilized. Third-year medical students self-selected into the study and were interviewed 1 year after entering the laboratory. Transcribed audiotapes of the interviews were analyzed for themes across the interviews. One year after dissection students have vivid memories with differing ways of viewing the body that may help or hinder with dissection. The themes presented include orientation, student anticipation, psychological approach to the body, normalizing-continuing disquiet, and social reference. The orientation eases student entry into the laboratory. There can be ongoing feelings of ambivalence regards the body for some students. Novel findings include that students not only have their own feelings to deal with but also those of friends and family who question them and may feel uncomfortable with the idea of them dissecting. Even one year after beginning dissection, students may emotionally struggle with their work and may require further support, including how they talk about sensitive topics with other people.     

Undergraduate coursework in anatomy as a predictor of performance: comparison between students taking a medical gross anatomy course of average length and a course shortened by curriculum reform

The performance of students taking medical gross anatomy at the University of California at Davis during a 4-year period (1999-2002) was correlated with prior undergraduate anatomy coursework. Significant correlations were observed between class rank in medical anatomy and taking any undergraduate anatomy as well as the total number of undergraduate anatomy units (P<0.01). Taking human gross anatomy and an anatomy laboratory course were significantly correlated with medical anatomy class rank (P<0.01) as were grades in human anatomy, comparative vertebrate anatomy and anatomy laboratory courses (P<0.05). The medical anatomy course offered in 1999-2000 was 172 hr long, and the course offered in 2001-2002 was 135 hr long, with most of the difference made by decreasing lecture time while sparing the dissection laboratory. The reduction in course length was the consequence of a curriculum-wide cap in weekly contact hours. In the 172-hr medical anatomy course there were significant correlations between the students who took undergraduate anatomy and both class rank and the score on the final examination (P<0.01). These correlations did not exist for the 135-hr course. This may be explained by previous anatomy experiences helping students learn from lecture more than from dissection laboratory, as well as the extra study time available to students in the reformed medical curriculum. Pre-medical students and health science advisors need to consider that the benefits of taking anatomy as an undergraduate may be dependent on the configuration of a medical school's curriculum.     

Survey of the educational roles of the faculty of anatomy departments

The anatomy dissection laboratory is a unique experience where medical students begin the transition from layman to physician, and may be a student's first experience with death. Attitudes developed there may influence interactions with future patients and their families. Consequently, anatomy faculty are in a position to recognize emotional issues that students may confront and to guide them toward becoming humane physicians. We surveyed anatomy faculty to assess acceptance of this expanded role and their means of meeting these obligations. A spokesperson for the anatomy department at each US and Canadian medical or osteopathic college (n = 142) was surveyed. One hundred three (73%) questionnaires were returned. Respondents overwhelmingly (93% agree or strongly agree) accept an educational role that includes helping students to become caring physicians and dealing with death and dying. Seventy-nine percent agree or strongly agree that the anatomy laboratory can affect students' later relationships with patients. Time for laboratory orientation is limited (55%, 1 hour or less) and is used to address technical topics, such as rules for student behavior. Most departments (58%) have four or more memorial activities to acknowledge the contribution of the donors. The anatomy faculty who responded to the survey accept responsibility for acculturating preclinical students to medicine. Respondents identified additional orientation topics and expanded memorial activities to accomplish this goal. Clin. Anat. 10:264–271, 1997. © 1997 Wiley-Liss Inc.     

The new face of gross anatomy

The nature of anatomy education has changed substantially over the past decade due to both a new generation of students who learn differently from those of past years and the enormity of advances in anatomical imaging and viewing. At Mount Sinai School of Medicine, our anatomy courses have been designed to meld classic dissection with the tools physicians and surgeons will use tomorrow. We introduce students to the newest technologies available for viewing the body, such as minimally invasive approaches, ultrasonography, three-dimensional visualizations, multi-axial computerized image reconstructions, multi-planar magnetic resonance imaging, and plastinated prosections. Students are given a hands-on, team-building experience operating laparoscopes in the laboratory. A great strength of our program is the important and active participation by faculty from 15 different basic and clinical departments, including several chairs and voluntary faculty. This interdisciplinary approach brings to our students direct, one-on-one encounters or presentations by our finest physicians and surgeons and our core anatomy faculty. In addition, the presence of many teaching assistants drawn from upper classmen and advanced graduate students adds an additional, vibrant dimension. Our anatomy programs for medical/graduate students and postgraduates are structured around three simple principles: (1) it is a privilege to teach, (2) we enlist only passionate teachers, and (3) it is our role to instill appreciation and respect for human form.     

Integrating gross pathology into teaching of undergraduate medical science students using human cadavers

Human cadavers offer a great opportunity for histopathology students for the learning and teaching of tissue pathology. In this study, we aimed to implement an integrated learning approach by using cadavers to enhance students' knowledge and to develop their skills in gross tissue identification, handling and dissection techniques. A total of 35 students enrolled in the undergraduate medical science program participated in this study. A 3‐hour laboratory session was conducted that included an active exploration of cadaveric specimens to identify normal and pathological tissues as well as tissue dissection. The majority of the students strongly agreed that the integration of normal and morbid anatomy improved their understanding of tissue pathology. All the students either agreed or strongly agreed that this laboratory session was useful to improve their tissue dissection and instrument handling skills. Furthermore, students from both cohorts rated the session as very relevant to their learning and recommended that this approach be added to the existing histopathology curriculum. To conclude, an integrated cadaver‐based practical session can be used effectively to enhance the learning experience of histopathology science students, as well as improving their manual skills of tissue treatment, instrument handling and dissection.     

A unique, innovative, and clinically oriented approach to anatomy education.

The establishment of The Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, whose first class entered in 2004, provided a unique opportunity to design an anatomy program that, from all indications, is effective, time efficient, and clinically relevant in the context of a nonlecture, problem-based, organ-systems-oriented curriculum. Through consultation with surgery colleagues, the case-directed anatomy program was developed. This approach, meeting one day a week for 1 hour 50 minutes for 30 weeks, uses clinical cases to introduce anatomical information that is reinforced using prosected cadavers and imaging. The format of the approach involves three steps: (1) students preview a clinical case with clinical questions and learning objectives, (2) students acquire basic knowledge using textbooks and self-directed learning modules, and (3) students reinforce their basic knowledge in weekly case-directed anatomy sessions, which involve an interactive discussion of the clinical case followed by a laboratory. In the laboratory, students rotate around stations viewing prosected cadavers and imaging. Learning anatomy does not stop after the first year, because the program is longitudinal. During the second year, students review anatomy in each organ-system course using the first-year format. Also, second-year students can assist the fellows or residents prepare the prosections for first-year students and for their review of anatomy in the second year. This provides students with a dissection experience. During third-year clinical rotations, anatomy knowledge is reinforced, and several surgery anatomy electives are available during the final year. In this way, anatomy is learned and reinforced throughout the medical school curriculum.     

Pathological analysis of cadavers for educational dissection by using postmortem imaging

This study was performed primarily to clarify whether pathological analysis of cadavers for anatomical dissection is possible using postmortem imaging (PMI), and whether this is worthwhile. A total of 33 cadavers that underwent systematic anatomical dissection at our medical school also underwent PMI. Fixative solution was injected into the corpus 3–4 days after death. PMI was then performed using an 8‐slice multi‐detector CT scanner 3 months before dissection. Before dissection, a conference was held to discuss the findings of the PMI. First, two radiologists read the postmortem images without any medical information and deduced the immediate cause of death. Then, the anatomy instructor revealed the medical information available. Based on this information, the radiologist, anatomy instructor, and pathologists suggested candidate sampling sites for pathological examination. On the last day of the dissection period, the pathologists resected the sample tissues and processed them for pathological examination. In 12 of 33 cases, the presumed causes of death could be determined based on PMI alone, and revision of the cause of death described in the death certificate was considered in five (15.2%) cases, based on PMI and pathological analysis. This article presents a novel method of pathological analysis of cadavers for anatomical dissection using PMI without disturbing the anatomy education of medical students.     

Gross anatomy: An outdated subject or an essential part of a modern medical curriculum? Results of a questionnaire circulated to final-year medical students

Final-year undergraduate medical students were given a questionnaire on the gross anatomy curriculum they had experienced in their first year at medical school 5 years earlier. They were asked to evaluate the relevance of the dissection course, lectures and seminars in gross anatomy for clinical courses, clerkships, and everyday practical work on the ward. About two-thirds of the students found the time spent on 10 different regions in anatomy to be adequate, and a considerable number of students would have liked even more details. The vast majority expressed a wish to repeat topographical anatomy during their clinical teaching. Furthermore, ～75% of the students showed interest in short, specialized dissection courses during the clinical curriculum. Medical students just before graduation ranked gross anatomy with the dissection course and integrated clinical topics as a keystone for their clinical courses. The results of such surveys should be taken into consideration when discussing modification to teaching gross anatomy or arguing about a balanced dissection course. © 1993 Wiley-Liss, Inc.     

Development of instructional, interactive, multimedia anatomy dissection software: a student-led initiative

Although dissection provides an unparalleled means of teaching gross anatomy, it constitutes a significant logistical and financial investment for educational institutions. The increasing availability and waning cost of computer equipment has enabled many institutions to supplement their anatomy curriculum with Computer Aided Learning (CAL) software. At the Royal College of Surgeons in Ireland, two undergraduate medical students designed and produced instructional anatomy dissection software for use by first and second year medical students. The software consists of full-motion, narrated, QuickTime MPG movies presented in a Macromedia environment. Forty-four movies, between 1-11 min in duration, were produced. Each movie corresponds to a dissection class and precisely demonstrates the dissection and educational objectives for that class. The software is distributed to students free of charge and they are encouraged to install it on their Apple iBook computers. Results of a student evaluation indicated that the software was useful, easy to use, and improved the students' experience in the dissection classes. The evaluation also indicated that only a minority of students regularly used the software or had it installed on their laptop computers. Accordingly, effort should also be directed toward making the software more accessible and increasing students' comfort and familiarity with novel instructional media. The successful design and implementation of this software demonstrates that CAL software can be employed to augment, enhance and improve anatomy instruction. In addition, effective, high quality, instructional multimedia software can be tailored to an educational institution's requirements and produced by novice programmers at minimal cost.
