There are three kinds of muscles: skeletal, heart, and smooth. Skeletal muscle makes up a major part of the animal body. It is the prime mover of animal locomotion. It is controlled by voluntary nerves. It has the feature that if it is stimulated at a sufficiently high frequency, it can generate a maximal tension, which remains constant in time. It is then said to be tetanized. The activity of the contracting mechanism is then thought to be maximal.
