Muscle Contraction Overview Animation

I found the entire muscle animation movie (prototype) that I describe in more detail here:

This was all storyboarded by Quade Paul (http://www.echomedicalmedia.com) and me with no content expert input or editing, so there are a number of errors... I had only been illustrating Cell Biology for about 6 months when we started this and hadn't yet taken a class, but most of the gross to histological level stuff is still canonical.
A year later, I had a much better understanding and also worked with content experts Ron Milligan and Ron Vale to create a more accurate depiction of the favored theory of Muscle Myosin (and Kinesin) as shown here http://www.youtube.com/user/grahamj21...
