Innervation of muscle contraction

The muscles that help us to move (skeletal muscles) are controlled by the motor neurons of the peripheral nervous system. The actions of the cerebrum and cerebellum initiate and coordinate the impulses that are sent to the muscles. This results in smooth and coordinated movement of the bones.

Skeletal muscle contraction involves many components and will be dealt with fully in the section on musculo-skeletal support.
