The central nervous system, is made up of the brain and spinal cord
The peripheral nervous system, is made up of pairs of nerves that originate from either the brain or the spinal cord
The peripheral nervous system is divided into:
Sensory neurones, which carry nerve impulses from receptors towards the nervous system.
Motor neurons, which carry nerve impulses away from the central nervous system to effectors.
The motor nervous system can be further subvided as follows:
voluntary nervous system which carries nerve impulses to body muscles ad under voluntary (concious) control.
autonomic nervous system which carried nerve impulses to galnds, smooth muscle and cardiac muscle and is not under voluntary control that is, it is involuntary (subconcious).
