The Nervous System

The Nervous System :

The nervous system of humans and other vertebrates consists of two major parts…the central nervous system (CNS) and the peripheral nervous system (PNS)…The CNS consists of the brain and the spinal cord. It occupies the commanding position in the nervous system, as it coordinates and integrates all bodily functions.

The PNS which transmits messages to and from the CNS has two divisions…somatic and autonomic. Autonomic nerves are motor nerves only. They regulate a great variety of bodily functions.
