Central nervous system

Also known as: CNS

One of the two main divisions of the human nervous system (the other being the peripheral nervous system), consisting of the brain and the spinal cord.

The main coordinating and controlling centre of the body, the central nervous system processes information to and from the peripheral nervous system.

The system is made up of grey matter (mostly nerve cells and associated parts) and white matter (mostly nerve fibres) and contains protective cerebrospinal fluid (CSF).
