Sliding Filament Theory 3d Model. In order to contract actin and myosin filaments must move past each other. To get the actin together the myosin has cross bridges which pull them near each other but the actin has proteins tropmyosin and troponin which stop the cross bridges from pulling them together.

Hanson 1954 explains how muscles in the human body contract to produce force. When a muscle contracts the actin is pulled along myosin toward the center of the sarcomere until the actin and myosin filaments are completely overlapped. It is proposed that muscle contracts by the actin and.
The sliding filament theory explains the basis of skeletal muscle contraction and specifically deals with the movement of myosin heads along an actin fiber in the sarcomere.
