Page 2 Major Subdivisions of the Nervous System
Graphic for structure of the nervous system
The human nervous system can be considered in three major subdivisions:
a. The central nervous system (CNS) which consists of the brain and the spinal cord.
b. The peripheral nervous system (PNS) which consists of the nerves which go from the CNS to the periphery of the body.
c. The autonomic nervous system (ANS) which is that portion of the nervous system concerned with commands for smooth muscle tissue, cardiac muscle tissue, and glands.
