Weband thin myofilaments to slide over each other, resulting in a shortening of each sarcomere, each skeletal muscle fiber, and the muscle as a whole—much like the two parts of an extension ladder that slide over each other. To summarize, in order for the shortening of the muscle to occur, the myosin heads have three important properties: 1.)
