Nervous System

The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous system contains the brain and spinal cord.

What is the Nervous System?

The nervous system is a complex network of neurons and cells that carry messages to and from the brain and spinal cord to various parts of the body.
