This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities.  相似文献

Medical schools in the United States continue to undergo curricular change, reorganization, and reformation as more schools transition to an integrated curriculum. Anatomy educators must find novel approaches to teach in a way that will bridge multiple disciplines. The cadaveric extraction of the central nervous system (CNS) provides an opportunity to bridge gross anatomy, neuroanatomy, and clinical neurology. In this dissection, the brain, brainstem, spinal cord, cauda equina, optic nerve/tract, and eyes are removed in one piece so that the entire CNS and its gateway to the periphery through the spinal roots can be appreciated. However, this dissection is rarely, if ever, performed likely due to time constraints, perceived difficulty, and lack of instructions. The goals of this project were (i) to provide a comprehensive, step‐by‐step guide for an en bloc CNS extraction and (ii) to determine effective strategies to implement this dissection/prosection within modern curricula. Optimal dissection methods were determined after comparison of various approaches/tools, which reduced dissection time from approximately 10 to 4 hours. The CNS prosections were piloted in small group sessions with two types of learners in two different settings: graduate students studied wet CNS prosections within the dissection laboratory and medical students used plastinated CNS prosections to review clinical neuroanatomy and solve lesion localization cases during their neurology clerkship. In both cases, the CNS was highly rated as a teaching tool and 98% recommended it for future students. Notably, 90% of medical students surveyed suggested that the CNS prosection be introduced prior to clinical rotations. Anat Sci Educ 11: 185–195. © 2017 American Association of Anatomists.  相似文献

The purpose of this study was to evaluate the extracurricular cadaveric dissection program available to medical students at an institution with a modern (time‐compressed, student‐centered, and prosection‐based) approach to medical anatomy education. Quantitative (Likert‐style questions) and qualitative data (thematic analysis of open‐ended commentary) were collated from a survey of three medical student cohorts who had completed preclerkship. Perceived benefits of dissection included the hands‐on learning style and the development of anatomy expertise, while the main barrier that limited participation was the time‐intensive nature of dissection. Despite perceived benefits, students preferred that dissection remain optional. Analysis of assessments for the MD2016 cohort revealed that dissection participation was associated with enhanced performance on anatomy items in each systems‐based unit examination, with the largest benefits observed on discriminating items that assessed knowledge application. In conclusion, this study revealed that there are academic and perceived benefits of extracurricular participation in dissection. While millennial medical students recognized these benefits, these students also indicated strong preference for having flexibility and choice in their anatomy education, including the choice to participate in cadaveric dissection.

Anatomical education has been undergoing reforms in line with the demands of medical profession. The aim of the present study is to assess the impact of a traditional method like cadaveric dissection in teaching/learning anatomy at present times when medical schools are inclining towards student‐centered, integrated, clinical application models. The article undertakes a review of literature and analyzes the observations made therein reflecting on the relevance of cadaveric dissection in anatomical education of 21st century. Despite the advent of modern technology and evolved teaching methods, dissection continues to remain a cornerstone of anatomy curriculum. Medical professionals of all levels believe that dissection enables learning anatomy with relevant clinical correlates. Moreover dissection helps to build discipline independent skills which are essential requirements of modern health care setup. It has been supplemented by other teaching/learning methods due to limited availability of cadavers in some countries. However, in the developing world due to good access to cadavers, dissection based teaching is central to anatomy education till date. Its utility is also reflected in the perception of students who are of the opinion that dissection provides them with a foundation critical to development of clinical skills. Researchers have even suggested that time has come to reinstate dissection as the core method of teaching gross anatomy to ensure safe medical practice. Nevertheless, as dissection alone cannot provide uniform learning experience hence needs to be complemented with other innovative learning methods in the future education model of anatomy.

The anatomical sciences have always been regarded as an essential component of medical education. In Canada, the methodology and time dedicated to anatomy teaching are currently unknown. Two surveys were administered to course directors and discipline leaders to gain a comprehensive view of anatomical education in Canadian medical schools. Participants were queried about contact hours (classroom and laboratory), content delivery and assessment methods for gross anatomy, histology, and embryology. Twelve schools responded to both surveys, for an overall response rate of 64%. Overall, Canadian medical students spend 92.8 (± 45.4) hours (mean ± SD) studying gross anatomy, 25.2 (± 21.0) hours for histology, and 7.4 (± 4.3) hours for embryology. Gross anatomy contact hours statistically significantly exceeded those for histology and embryology. Results show that most content is delivered in the first year of medical school, as anatomy is a foundational building block for upper-year courses. Laboratory contact time for gross anatomy was 56.8 (± 30.7) hours, histology was 11.4 (± 16.2) hours, and embryology was 0.25 (± 0.6) hours. Additionally, 42% of programs predominantly used instructor/technician-made prosections, another 33% used a mix of dissection and prosections and 25% have their students complete cadaveric dissections. Teaching is either completely or partially integrated into all Canadian medical curricula. This integration trend in Canada parallels those of other medical schools around the world where programs have begun to decrease contact time in anatomy and increase integration of the anatomical sciences into other courses. Compared to published American data, Canadian schools offer less contact time. The reason for this gap is unknown. Further investigation is required to determine if the amount of anatomical science education within medical school affects students' performance in clerkship, residency and beyond.  相似文献

Ultrasonography is a noninvasive imaging modality, and modern ultrasound machines are portable, inexpensive (relative to other imaging modalities), and user friendly. The aim of this study was to explore student perceptions of the use of ultrasound to teach “living anatomy”. A module utilizing transthoracic echocardiography was developed and presented to undergraduate medical, science, and dental students at a time they were learning cardiac anatomy as part of their curriculum. Relevant cardiac anatomy was explored on a student volunteer and images were projected in real‐time to all students via an AV projection system. Students were asked to complete a questionnaire about the learning experience and were given the opportunity to provide open feedback. The students' evaluations of this learning experience were very positive. They agreed or strongly agreed that it was an effective way to teach anatomy (90% medical; 77% dental; 100% science) and that it was incorporated in a way that promoted reinforcement of the lecture material (83% medical; 76% dental; 100% science). They agreed or strongly agreed with statements that the experience was innovative (93% medical; 92% dental; 100% science) and stimulated interest in the subject matter (86% medical; 75% dental; 96% science), and that they would like to see more modules, exploring other anatomical sites, incorporated into the curricula (83% medical; 72% dental; 100% science). We believe that ultrasound could be a useful tool, in conjunction with traditional teaching methods, to reinforce the learning of anatomy of a variety of different undergraduate student groups.

Thiel‐embalmed cadavers, which have been adopted for use in anatomy teaching in relatively few universities, show greater flexibility and color retention compared to formalin‐embalmed cadavers, properties which might be considered advantageous for anatomy teaching. This study aimed to investigate student attitudes toward the dissection experience with Thiel‐ compared to formalin/ethanol‐embalmed cadavers. It also aimed to determine if one embalming method is more advantageous in terms of learning functional anatomy through the comparison of student anterior forearm functional anatomy knowledge. Student opinions and functional anatomy knowledge were obtained through use of a questionnaire from students at two medical schools, one using Thiel‐, and one using more traditional formalin/ethanol‐embalmed cadavers. Both the Thiel group and the formalin group of students were surveyed shortly after completing an anterior forearm dissection session. Significant differences (P‐values <0.01) in some attitudes were found toward the dissection experience between cohorts using Thiel‐ vs. formalin‐embalmed cadavers. The Thiel group of students felt more confident about recognizing anatomy in the living individual, found it easier to identify and dissect anatomical structures, and indicated more active exploration of functional anatomy due to the retained flexibility of the cadaver. However, on testing, no significant difference in functional anatomy knowledge was found between the two cohorts. Overall, although Thiel embalming may provide an advantageous learning experience in some investigated areas, more research needs to be carried out, especially to establish whether student perception is based on reality, at least in terms of structure identification.

The teaching of human anatomy has had to respond to significant changes in medical curricula, and it behooves anatomists to devise alternative strategies to effectively facilitate learning of the discipline by medical students in an integrated, applied, relevant, and contextual framework. In many medical schools, the lack of cadaver dissection as the primary method of learning is driving changes to more varied and novel learning and teaching methodologies. The present article describes the introduction and evaluation of a range of body painting exercises in a medical curriculum. Body painting was introduced into integrated clinical skills teaching sessions which included clinically important aspects of respiratory system, musculoskeletal system, and topics in regional anatomy including head and neck. Nontoxic body paints, easels, a mixture of brush sizes, and anatomical images were supplied. Students were allowed between 20 and 40 min to complete body painting tasks, in which they were encouraged to alternate between painting and acting as a model. Students were encouraged to use life‐like rendering and coloration where appropriate. Evaluation of these sessions was performed at the end of the semester as part of a larger evaluation process. The kinesthetic nature and active participation together with the powerful visual images of underlying anatomy appear to contribute to the value of body painting as a teaching exercise. In addition, it may have the added bonus of helping break down apprehension regarding peer–peer examination. Some practical advice on introducing this method of teaching in medical curricula based on the outcomes of the evaluation is given. On the basis of our experience and student feedback, we strongly advocate the use of body painting as an adjunct to surface anatomy and clinical skills teaching classes.

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.

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem‐based learning (PBL) curriculum. PBL is a well‐established student‐centered approach, and the authors have sought to examine if a student‐centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self‐directed learning questions. All IRSs were primarily directed by students. During two second‐semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student‐centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non‐IRS blocks. A student‐centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first‐year medical students.

The role of human dissection in modern medical curricula has been a topic of intense debate. In part, this is because dissection can be time-consuming and curricular hours are being monitored more carefully. This has led some to question the efficacy and importance of dissection as a teaching method. While this topic has received considerable attention in the literature, the question of how dissection impacts learning has been difficult to evaluate in a real-world, high-stakes setting since participation in dissection is often one of many variables. In this study, this challenge was overcome due to a change in the curriculum of a Special Master Program (SMP) that permitted a comparison between two years of students that learned anatomy using prosection only and two years of students that participated in dissection laboratories. Since each class of SMP students took courses in the medical school, and the medical school anatomy curriculum was constant, medical student performance served as a control throughout the study period. Results demonstrate that SMP students who learned through prosection had lower performance on anatomy practical and written examinations compared to medical students. When the SMP program changed and students started participating in dissection, there were measurable improvements in both practical and written examinations. These findings provide evidence of dissection’s role in learning and applying anatomy knowledge both within and outside the gross anatomy laboratory.  相似文献

Rapid changes in medical knowledge are forcing continuous adaptation of the basic science courses in medical schools. This article discusses a three‐year experience developing a new Computed Tomography (CT)‐based anatomy curriculum at the Sackler School of Medicine, Tel Aviv University, including describing the motivations and reasoning for the new curriculum, the CT‐based learning system itself, practical examples of visual dissections, and student assessments of the new curriculum. At the heart of this new curriculum is the emphasis on studying anatomy by navigating inside the bodies of various living individuals utilizing a CT viewer. To assess the students’ experience with the new CT‐based learning method, an anonymous questionnaire was administered at the end of the course for three consecutive academic years: 2008/2009, 2009/2010, 2010/2011. Based upon the results, modifications were made to the curriculum in the summers of 2009 and 2010. Results showed that: (1) during these three years the number of students extensively using the CT system quadrupled (from 11% to 46%); (2) students' satisfaction from radiologists involvement increased by 150%; and (3) student appreciation of the CT‐based learning method significantly increased (from 13% to 68%). It was concluded that discouraging results (mainly negative feedback from students) during the first years and a priori opposition from the teaching staff should not weaken efforts to develop new teaching methods in the field of anatomy. Incorporating a new curriculum requires time and patience. Student and staff satisfaction, along with utilization of the new system, will increase with the improvement of impeding factors.

For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on‐going. We hypothesize that three‐dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi‐colored and multi‐material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ～1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi‐colored, multi‐material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.

Due to the current trend of decreasing contact hours and less emphasis being given to the basic science courses in the pre-clinical years of medical education, it is essential that new approaches to teaching gross anatomy are investigated to ensure medical students are being adequately exposed to anatomical content. This study retrospectively analyzed practical examination data from four medical gross anatomy classes (N = 569) to ascertain which pedagogical approach, student participation in the dissection process, or interaction with prosected specimens is best for teaching the anatomy of the hand and foot. Data analysis involved the use of propensity score matching, a nonparametric preprocessing statistical approach which ensures accurate representation of the true treatment effect by balancing cohorts prior to statistical analysis. Statistical analysis indicated that those students who were exposed to the anatomy of the hand through interactions with prosected specimens performed 5.6% better (P = 0.012) while for the foot, students who interacted with prosections performed 13.0% better (P < 0.001). Although limited, data from this study suggest that utilizing prosections of the hand and foot seems to be a more advantageous pedagogical approach for teaching these regions than requiring students to dissect them.  相似文献

A stand‐alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The module was developed using “in‐house” software designed for academics with minimal computer experience. The efficacy and effectiveness of the module was gauged via student surveys, testing student knowledge before and after module introduction, and analysis of final examination results. At least 74% of the class used the module and student responses were positive regarding module usability (navigation, interaction) and utility (learning support). Learning effectiveness was demonstrated by large significant improvements in the post‐presentation test scores for “users” compared with “non‐users” and by the percentage of correct responses to relevant multiple choice questions in the final examination. Performance on relevant short answer questions in the final examination was, on average, comparable to that for other components. Though limited by study structure, it was concluded that the module produced learning outcomes equivalent to those generated by more traditional teaching methods. This “Do‐It‐Yourself” e‐learning approach may be particularly useful for meeting specific course needs not catered for by commercial applications or where there are cost limitations for generation of online learning material. The specific approaches used in the study can assist in development of effective online resources in anatomy. Anat Sci Educ 6: 107–113. © 2012 American Association of Anatomists.  相似文献

Traditional dissection teaching is being reduced in a number of medical schools, particularly in the United Kingdom. In response to this, 12 medical students from Warwick University, UK, traveled to the Island of Grenada for an intensive extracurricular dissection course at St. George's University. This course not only benefited the host university through the creation of prosections for teaching but also allowed the participants to completely immerse themselves in anatomical study, by developing their dissection skills and consolidating anatomical knowledge. We believe that similar courses could be easily implemented by other medical schools, thereby allowing future students to keep traditional dissection alive.

Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. Among the difficult anatomical concepts that students struggle to understand, the anatomy of the peritoneal cavity with its complex projections of peritoneum could benefit strongly from new learning aids. In this report, an innovative teaching tool is presented to engage students during both lecture and laboratory, and help them build three‐dimensional (3D) mental maps of peritoneal cavity. The model consists of a patchwork of mesenteries and gut made from colored cloth stitched together onto a T‐shirt to denote the origin and outflow of each peritoneum projection. As the lecturer wears the life‐size model, the students can appreciate the 3D organization of the peritoneal cavity on a living body. In addition, the T‐shirt model can be used in parallel with dissection to ensure a strong reinforcement of the spatial understanding of the peritoneal cavity.

It has become increasingly apparent that no single method for teaching anatomy is able to provide supremacy over another. In an effort to consolidate and enhance learning, a modernized anatomy curriculum was devised by attempting to take advantage of and maximize the benefits from different teaching methods. Both the more traditional approaches to anatomy teaching, as well as modern, innovative educational programs were embraced in a multimodal system implemented over a decade. In this effort, traditional teaching with lectures and dissection was supplemented with models, imaging, computer‐assisted learning, problem‐based learning through clinical cases, surface anatomy, clinical correlation lectures, peer teaching and team‐based learning. Here, we review current thinking in medical education and present our transition from a passive, didactic, highly detailed anatomy course of the past, to a more interactive, as well as functionally and clinically relevant anatomy curriculum over the course of a decade.

Understanding the three‐dimensional (3D) nature of the human form is imperative for effective medical practice and the emergence of 3D printing creates numerous opportunities to enhance aspects of medical and healthcare training. A recently deceased, un‐embalmed donor was scanned through high‐resolution computed tomography. The scan data underwent segmentation and post‐processing and a range of 3D‐printed anatomical models were produced. A four‐stage mixed‐methods study was conducted to evaluate the educational value of the models in a medical program. (1) A quantitative pre/post‐test to assess change in learner knowledge following 3D‐printed model usage in a small group tutorial; (2) student focus group (3) a qualitative student questionnaire regarding personal student model usage (4) teaching faculty evaluation. The use of 3D‐printed models in small‐group anatomy teaching session resulted in a significant increase in knowledge (P = 0.0001) when compared to didactic 2D‐image based teaching methods. Student focus groups yielded six key themes regarding the use of 3D‐printed anatomical models: model properties, teaching integration, resource integration, assessment, clinical imaging, and pathology and anatomical variation. Questionnaires detailed how students used the models in the home environment and integrated them with anatomical learning resources such as textbooks and anatomy lectures. In conclusion, 3D‐printed anatomical models can be successfully produced from the CT data set of a recently deceased donor. These models can be used in anatomy education as a teaching tool in their own right, as well as a method for augmenting the curriculum and complementing established learning modalities, such as dissection‐based teaching.
