If you haven't been to Google Labs lately you should check out Google Body.
Google Body is a detailed 3D model of the human body. You can peel back anatomical layers, zoom in, and navigate to parts that interest you. Click to identify anatomy, or search for muscles, organs, bones and more.
You can also share the exact scene you are viewing by copying and pasting the corresponding URL. You will need a web browser that supports WebGL, such as Google Chrome.
Please send Google feature requests and feedback via the form linked at the bottom right of the app. Male model is coming soon!

So much more interesting and cooler than an anatomy textbook.
