The nervous system is a complex collection of nerves and
... The nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli, transmit stimuli to nervous centers, and to initiate response. The central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. ...
