Scene 9: Musculature of Hand (Structure of the Muscle Fibers)

Muscle figures display in the background. Another six pieces at the center part can be move by mouse dragging. A cross section of the muscle fibers hides at the back. The cross section of the muscle fibers is breathing at the center of the stage. The background muscle pieces are also breathing slowly to change the size. When clicking the circles (Myofibril) inside the cross section muscle fiber, screen will zoom in to it.

The enlarging cross-section of the muscle fibers is showing on the stage. When mouse rollovers on the stage, some of the cross-section fibers will rise up. Close up of the center muscle fiber is showed. Mouse rollovers the circles (Myofibril) inside the muscle fiber, it may have 3 different results: first one shows the Thin (actin) filament, second one shows the Thick (myosin) filament, and the third one shows actin running.
