The animation shows the interaction of actin, myosin, tropomyosin, ATP, Ca, Mg and troponin. The animation panel can run continuously to repeatedly show the events. A definitions panel provides a key to the molecules involved in this complex process of skeletal muscle contraction. It can be downloaded and played as a standalone. This animation of cross-bridge formation and sliding filaments graphically shows the molecules involved.
