Computer-Based Dissection Manual (CBDM) of the Upper Extremity
|Image, Tutorial, Lab Guide||9065||1||January 3, 2012|
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. The 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 the CBDM was to increase the efficiency of dissection in the gross anatomy laboratory, improve dissection techniques, and stimulate active, self-directed learning. The content is presented in a series of labeled digital images of the upper extremity dissection along with the written dissection instruction. The material is arranged in seven sections:
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
The Palm of the Hand
Each section contains multiple steps required to complete the dissection module.
The program is menu-driven, allows for viewing of the entire content in sequence, or, selected sections or steps in any order. The CBDM is intended as an anatomy laboratory visual guide, which might be used as a supplement to a cadaver dissection manual.

Effectiveness and Significance
The Computer-Based Dissection Manual (CBDM) of the Upper Extremity was used as a supplementary source to the mandatory Gray’s Dissection Guide. The CBDM of the Upper Extremity was available online for first year medical students enrolled in the Human Structure course at Wright State University. Students were able to study labeled digital images of the assigned dissection, along with the short dissection instructions, prior each laboratory in order to spend, class time more effectively in active dissection. The high resolution images were available for view without labels to provide students with opportunities for repetition and self-assessment.
After the first year, use of the CBDM was evaluated by all first year medical students. The vast majority of students (94%) decided to use this new tool, which was recommended, but not required. The CBDM was used by 93% students who had no prior dissection experience, and by 96% students who have done cadaver dissection previously. Among all CBDM users, 97% found it very useful or somewhat useful. Most of the users (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.
Special Implementation Guidelines or Requirements
The Computer-Based Dissection Manual (CBDM) is an html-based collection of images and instructions that may be viewed using a standard web browser.
To view the CBDM:
- Double “click” on the Upper Limb Website, open the folder and double click the UpperLimb.html file -this should start your default browser and open the file.
- The UpperLimb.html contains links to the seven sections of the website.Select the title of the chosen section and click on it.
- Each section is broken down into the several steps which can be accessed from that sections main page by clicking on it.
- Each step has navigation links at the top and at the bottom of the page to move to the next or previous step, or return to the table of contents page.
- The pictures on each step can be clicked on to open a larger image. A link below the picture will open the image without labels.
- Each section also contains a review at the end with links to the appropriate steps.
- For the names of the structures yellow labels are used when structure is mentioned first time (in the text or on the picture); white labels are used to indicate structures that have already been introduced in previous images.
Creation of CBDM was considerably time consuming, but the effort seemed to be rewarding. Positive student comments and suggestions were encouraging. The results of the evaluation provided many recommendations for developing other parts of the CBDM in the future. Using the CBDM seemed to be beneficial, especially for visual learners, but if and how this improves the performance on laboratory/practice exams must be further researched. The CBDM can be used as an independent, powerful tool to preview the material before class and reinforce learning issues after the laboratory session.
