Computer-Based Dissection Manual (CBDM) of the Upper Extremity

Abstract

Abstract This resource is an online computer-based dissection manual (CBDM) of the upper extremity directed toward first-year medical, dental, or other students taking human gross anatomy courses with a dissection laboratory component. This CBDM provides a resource to guide students through the requisite steps of each dissection module and serves as a powerful tool for independent study and review. The purpose of creating this CBDM was to increase the efficiency of dissection in the gross anatomy laboratory, improve dissection techniques, and stimulate active, self-directed learning. Content is presented in a series of labeled digital images of the upper extremity dissection along with written dissection instruction. The material is arranged in seven sections: scapular region, pectoral region and axilla, axilla—arteries and nerves, anterior and posterior arm, cubital fossa and forearm flexors, extensors of the forearm and dorsum of the hand, and palm of the hand. Each section contains multiple steps required to complete the dissection module. The program is menu driven and allows for viewing of the entire contents in sequence or selected sections or steps in any order. This CBDM was used as a supplementary source to the mandatory Gray's Dissection Guide. The CBDM was available online for first-year medical students enrolled in the human structure course at Wright State University. After the first year, use of the CBDM was evaluated by all first-year medical students. The vast majority (94%) decided to use this new tool, which was recommended but not required. The CBDM was used by 93% of students who had no prior dissection experience and by 96% of students who had done cadaver dissection previously. Among all CBDM users, 97% found it very useful or somewhat useful. Most (95%) wanted to use it for additional preparation for the practical lab exam. All students concluded that the CBDM was a very helpful, user-friendly resource and suggested that all dissection modules should be developed in this format. Faculty members noticed that the CBDM accelerated the dissection process, increased of the efficiency of dissection, and improved dissection techniques.
