Summary Introduction
Introduction:
Nervous system controls and coordinates the functions of body. The nervous system has two divisions: central nervous system (CNS) and peripheral nervous system (PNS). The central nervous system consists of spinal cord and brain. Peripheral nervous system comprise of afferent nervous system and efferent nervous system.
