Muscles are specialized tissues evolved for movement. Smooth muscle is involved in involuntary movement found in the contraction of blood vessels, the digestive tract and the iris, and also the formation of goose bumps. Skeletal muscle is a type of striated muscle involved in voluntary movement and is the muscle we are most familiar with that allows us to move our bodies. Cardiac muscle is also a type of striated muscle, although some people use it to mean skeletal muscle only, and is involved in the contraction of the heart which is the pumping motion that moves the blood throughout the body.
Striated (or skeletal) muscle
Isotonic contractions are the type that involve muscle movement. This movement is due to a change in length as the muscle fibers shorten or lengthen.

It is the Rubrospinal Tract. It's main role is the mediation of voluntary movement. It is responsible for large muscle moments such as the arms and legs as well as fine muscle movement.
