What a fantastic Human Anatomy learning tool! Select and view the male or the female body or select from the Major Categories : Full Figure, head, spine, chest, abdomen, pelvis and extremities. Easy to use. Colorful 2D/3D parts. Here's how you do it! Example: Select male, scroll down Major Category (left side bar) and select full body or an individual body part. Let's select the BRAIN. The center viewing screen shows a rotating brain. Touch the brain and rotate as you like, able to enlarge the view as well. At the top is a sub-category displaying other brain images. Select one or continue on by selecting your data, On the right side bar, scroll through and select CERVICAL NERVES. That specific image displays along with a text/data box. A terrific app for students and medical professionals. Makes studying easier and more fun then referencing from a book!
