Computer-Based Dissection Manual (CBDM) – Cranium
|Image, Tutorial, Lab Guide||9314||1||January 17, 2013|
This resource is a skull tutorial, which is part of the online Computer-Based Dissection Manual (CBDM) directed toward first year medical, dental or other students taking human gross anatomy courses with a dissection component. The skull tutorial serves as preparation for the head and neck dissection. It consists of a series of digital images (including newborn skulls) illustrating bones, foramina, bony landmarks, processes, and protuberances, which are labeled, but can be viewed without labels in high resolution. The CBDM – Cranium provides a resource to help students approach the head and neck dissection module, and serves as a powerful tool for independent study and review. The purpose of the CBDM – Cranium is to increase the efficiency of dissection in the gross anatomy laboratory (during dissection students must refer to bony landmarks on the skull) while stimulating active, self-directed learning.
The material is divided into four sections, which contain multiple steps:
- Skull – Calvaria and Mandible
- Skull – Anterior View
- Skull – Lateral and Inferior View
- Skull – Cranial Fossae and Sphenoid Bone
Every section begins with a set of 10 fill-in-blank pre-test questions, which allow students to assess their current knowledge of the presented material. The following part of each section contains an online atlas of the skull with high quality digital images available both with and without labels for student’s study. The next fraction consists of an interactive exercise (5-6 practical quizzes) which allows students to apply acquired knowledge (toggle the labels). Each section ends with 10 multiple choice post-test questions, which enable learners to determine their improvement. Pre-and post-test questions, as well as practical quizzes stimulate active, self-directed learning and let students easily determine their increase in knowledge after studying the provided material. This also makes the study more attractive and attention-grabbing. The program is menu-driven, allowing students to view all of the content in sequence, or to view selected sections or steps in any order. The CBDM – Cranium is intended as an anatomy laboratory visual guide that may be used as a supplement to a cadaver dissection manual, giving students the opportunity for self-learning and self-assessment. Knowledge of skull osteology is essential for understanding head anatomy and for interpreting the standard radiographs and other imaging techniques such as CT, MRI, and PET.

Effectiveness and Significance
Since the “Computer-Based Dissection Manual (CBDM) – Cranium” presented in the current format (including interactive exercise) will be introduced to the medical students at Boonshoft School of Medicine in fall of 2013, we cannot describe its effectiveness. After all, we strongly believe that exposing first year medical students to the skull tutorial provides them with the essential osteology that is required for interpretation of standard radiographs and more contemporary imaging techniques such as CT, MRI and PET.
Special Implementation Guidelines or Requirements
The Computer-Based Dissection Manual (CBDM) of the Cranium is an html-based collection of images and instructions that may be viewed using a standard web browser. The program is menu-driven, allowing students to view all of the content in sequence, or to view selected sections or steps in any order. The main menu is located on the left side of the homepage. Clicking on any one of the menu sections displays the titles of several steps which are the contents of each session. Each step has navigation links at the top and bottom of the page to move to the next or previous step. Users may also return to the table of contents page by clicking the link available on each step. A link below each picture will open the image without labels, which allows for self-assessment. Each section contains set of 10 pre-and 10 post-test questions, review of study material with links to the appropriate steps, and 5-6 practical quizzes, which stimulate active, self-directed learning.
Using the CBDM – Cranium seems to be beneficial, especially for visual learners, but if and how this resource improves performance on anatomy examinations or increases the efficiency of dissection must be researched in the future.
