The purpose of this study was to dissect various animal larynges in support of a proposal for a laryngeal dissection laboratory. It was found that although the bovine larynx is larger than the human larynx, the anatomy is similar. Thirty-three bovine larynges were dissected by the author in various simulated phonosurgical and partial laryngectomy procedures. Following each procedure, the specimen was photographed for teaching purposes. The author concludes that dissecting bovine larynges offers a valuable aid to training in the field of laryngeal surgery. It is intended to apply these dissections in the form of a departmental surgical workshop.

European Annals of Otorhinolaryngology,... Sep 2011To evaluate the psychological preparation and stress of medical students associated with their first cadaver dissection class, covering the head and neck region.
OBJECTIVE
To evaluate the psychological preparation and stress of medical students associated with their first cadaver dissection class, covering the head and neck region.
MATERIALS AND METHODS
Prospective evaluation of a group of 58 second-year medical students.
RESULTS
Participants experienced this first dissection class with little stress, with no significant gender difference. Men, however, felt better prepared than the women did. The smell and sight of the cadaver's face were their main concerns.
DISCUSSION
The students were evaluated with STAI questionnaires and visual analog scales just before, immediately after, and one month after their first dissection experience. This is the first time this scheme has been used. Students suggested several improvements for advance preparation, most of them inexpensive in terms of human and material resources. The low stress caused by dissection is probably influenced by the fact that student participation is voluntary.
CONCLUSION
Although they felt that they were relatively unprepared from a psychological perspective, the vast majority of students felt ready to participate in the dissections and had a very good perception of this experience.

Anatomy is a major basic subject in medicine and related biomedical sciences. A central tool most universities use for teaching anatomy is the "dissection course", in which medical students learn the basic constructional principles of the human body by dissecting a cadaver. In recent years, the relevance and value of the dissection laboratory have been under discussion at different universities due to high costs and problems of shortness in time in some medical curricula. Indeed, during the last 10 years, several universities in the US and the UK have abandoned dissection and have moved from a cadaver-oriented to a cadaverless anatomy. This development results in a fundamental discussion on the role of the "dissection course" in the medical curriculum, ultimately raising the question as to whether we should continue teaching anatomy by dissection. This article presents nine arguments for the dissection course as a central tool for teaching macroscopic anatomy and is an attestment to the continuation of the use of cadaver material in anatomical laboratories within the auspices of scholastic and university order for the benefit of future physicians with due respect and honour guaranteed for every donor.

The usual dissection by medical students of the anterior abdominal wall and the inguinal region proceeds from superficial to deep; special emphasis is placed on the sheath of the rectus abdominis muscle and lateral muscular layers. We suggest an alternate approach to dissection of this region that has the following advantages: (1) sparing of delicate deep structures not often fully appreciated by students; (2) provision of an opportunity to visualize the region from a laparoscopic surgeon's vantage point; (3) considerably reduced time spent dissecting and identifying structures and relationships, especially peritoneal reflections important in laparoscopic procedures. Our dissection begins with bilateral subcostal incisions through the entire thickness of the anterior abdominal wall and peritoneum, which extend laterally and inferiorly to the level of the anterior superior iliac spines, thereby forming a large, inverted, U-shaped flap. This flap is reflected inferiorly, allowing abdominal viscera to be dissected, and ultimately removed en bloc. The flap is then drawn cranially and stretched somewhat to approximate its position when the abdomen is inflated with CO2 during laparoscopic procedures. Major landmarks, including the deep inguinal ring, are noted and the flap is again reflected inferiorly for dissection beginning with the peritoneum and transversalis fascia. This method of dissecting the anterior abdominal wall and inguinal region results in more facile and timely identification of both superficial and deep structures of the anterior abdominal wall and inguinal region, and provides a clinically relevant demonstration of anatomy from a laparoscopic perspective.

Anatomy is an essential component of clinical anesthesiology. The use of simulated patients and alternative materials, including embalmed human bodies, have become increasingly common during resident physician training due to the deemphasis on anatomical education during undergraduate medical training. In this report, the need for a more extensive review of relevant anatomy for the practice of anesthesiology was addressed by the design, evaluation, and dissemination of a human dissection course for procedural training of anesthesiology residents. The course utilized "freedom art" embalmed human bodies that allowed trainees to perform ultrasound-based regional and neuraxial techniques followed by detailed dissections of critical anatomy. One hundred and four residents participated in workshops and small group discussions and were evaluated using pre- and post-course assessments. A variety of clinical techniques were performed on the bodies, including regional blocks and neuraxial catheter placement. Insertion of peripheral/neuraxial catheters was successful, with dissections demonstrating the expected placement. Assessment scores improved following the course (pre-course mean 52.7%, standard deviation (σ) 13.1%; post-course mean 72.2%, σ 11.6%; t-test p < 0.0001) and feedback highlighted the usefulness and clinical relevance of course content. The ability to correlate ultrasound imaging with subsequent dissections of the "blocked" area and visualization of dye staining was extremely relevant for spatial understanding of the anatomy relevant for the clinical practice of these techniques. This manuscript demonstrates successful implementation of a comprehensive course for anesthesiology resident physicians to address gaps in undergraduate anatomical education and suggests that broader adoption of dissection courses may be beneficial for training anesthesiologists.

Analysis of neuromuscular junction morphology can give important insight into the physiological status of a given motor neuron. Analysis of thin flat muscles can offer significant advantage over traditionally used thicker muscles, such as those from the hind limb (e.g. gastrocnemius). Thin muscles allow for comprehensive overview of the entire innervation pattern for a given muscle, which in turn permits identification of selectively vulnerable pools of motor neurons. These muscles also allow analysis of parameters such as motor unit size, axonal branching, and terminal/nodal sprouting. A common obstacle in using such muscles is gaining the technical expertise to dissect them. In this video, we detail the protocol for dissecting the transversus abdominis (TVA) muscle from young mice and performing immunofluorescence to visualize axons and neuromuscular junctions (NMJs). We demonstrate that this technique gives a complete overview of the innervation pattern of the TVA muscle and can be used to investigate NMJ pathology in a mouse model of the childhood motor neuron disease, spinal muscular atrophy.

An innovative series of dissections of the canine abdomen was created to facilitate social distancing in the dissection room following COVID-19 restrictions imposed in the UK. In groups of six, first-year veterinary students took turns dissecting selected parts of the canine abdomen while maintaining social distancing and documenting their work with video and photographs. Here, students learned about the canine abdominal anatomy by dissecting, recording the dissections of others in their group, and compiling the recorded material into a collaborative electronic media portfolio (Wiki). An online formative multiple-choice test was created to test students' knowledge of the canine abdominal anatomy. The result analysis showed that although students achieved the learning outcomes only by studying the Wiki, they had better performance in the anatomical areas where they learned through the dissection (p < 0.05). Student performance was very similar in the areas in which they were present in the dissection room and participated in recording the dissection compared with the areas that they effectively dissected (p > 0.05). A qualitative thematic analysis was developed to understand students' opinions via their feedback on this dissection approach. Our results showed that student collaboration and the development of practical skills were the most valued aspects of this dissection teaching initiative. Moreover, these results show that developing a group Wiki has a positive impact on student achievement of learning objectives, with a practical hands-on dissection being fundamental for the optimal learning of the canine abdominal anatomy.

Practical training in the dissection of human cadavers is a fundamental and traditional component of human anatomy education in medical schools. This practice, however, can be stressful for students and can generate a certain amount of anxiety. The aim of this study is to explore the attitudes, reactions, and anxiety levels of first-year medical students when working in the dissecting room, over a period of one year, and to relate these anxiety levels to the results of our educational program. This is a before and after descriptive study of students at the University of Castilla-La-Mancha. Questionnaires were distributed among them before and after their dissection practices in order to understand their feelings and emotions and their satisfaction about this activity. State-Trait Anxiety Inventory questionnaires were used to assess the students' 'state anxiety' (SA), which dropped significantly from 49.1% to 14% by the end of their first year. Female students started with higher levels of SA than their male counterparts but by the end of the year these had dropped to similar levels. Anxiety and fearful thoughts tended to drop (P > 0.05). In contrast, uncertainty levels showed significant changes, falling from 44.4% to 12.3%. Nonetheless, 100% of students would go through the experience again. Indeed, 98.2% considered that dissection practices were useful in reinforcing the theoretical aspects of their education, and 80.7% believed that dissecting was more useful than theoretical models. Although students were satisfied with dissection practices the experience cause stressful responses.

Even in the rapidly changing field of cadaver dissection, published guide books still play an important role in the anatomy lab. However, commercial manuals with lengthy volumes and inflexible copyrights have several limitations which can be complemented by open-source manuals. Recently, the authors have manufactured and distributed a free electronic dissection manual (anatomy.co.kr), where descriptions are written concisely and images are drawn schematically. Moreover, simplified signs are employed to represent the cadaver viewing angles and manner of dissection. Based on the original files of this manual, other anatomists can revise and utilize the descriptions and figures. We expect many updated versions of our manual to be shared between students all over the world.
