For medical professionals, learning about the human body is crucial. A number of sites hold vast stores of knowledge about the human body, and this interactive site is one resource that persons in this field should know about. Created by Dr. Frederick Wezeman and Dr. John Santaniello of Loyola University's Stritch School of Medicine, the site contains a series of interactive dissection exercises, a cross-sectional tutorial, and some very helpful flash cards. One feature that should not be missed is the "Learn 'Em" area. Here, visitors can learn about the structure and location of various arteries, nerves, and dermatomes. The site concludes with a thematically-organized collection of external anatomy links.
