The peripheral nervous system (PNS) is one of the two main parts of the nervous system, the other being the central nervous system (CNS). The PNS is made up of the neurons that extend outside of the brain and spinal cord, to the limbs and organs.[1] The PNS consists of two parts, the autonomic and somatic nervous systems. The autonomic nervous system controls the visceral or involuntary functions of the body, for example the cardiovascular system. The somatic nervous system controls the voluntary and conscious movements of the body, and so involves the control of all skeletal muscle. [2]
