The nervous system is the body’s main control system. It constantly receives input from variety of sources simultaneously. It controls body's physical movements, maintains homeostasis and initiates our thought processes and emotions.

The Nervous system has two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS) that has somatic and autonomic divisions. CNS consisting of the brain and spinal cord, and PNS consisting of all nervous tissue that lie outside the CNS.

The central nervous system receives, processes, and stores information. The peripheral nervous system provides sensory input and motor output.
