The "Sarcomere - Sliding Filament Model" was born of necessity as most inventions are. While teaching classes on the subject of muscular contraction, it became obvious that verbal descriptions of the contractile process in striated skeletal muscle were terribly inadequate. Making a drawing on a blackboard was no more effective than the pictures in a textbook. Few students could really comprehend the process of the sliding filament theory wherein a muscle can change its overall length, yet none of its individual parts ever changed length, they slide past each other.

This fascinating model represents the parts of a sarcomere, the contractile unit of striated skeletal muscle. The sarcomere is not round, it has a hexagon shape as represented in the model. Actin and myosin filaments, the Z-band, the M-line are all represented on this model.
