What does the nervous system consist of and what does it do?

Your nervous system is divided into two parts:

- The central nervous system (CNS) which is made up of the brain and the spinal cord.

- The peripheral nervous system is all the other nerve fibres that connect to it.

Functions:

-Together, they take in information about the outside world through special receptor cells and each cell responds to a specific stimulus.

- They then pass the information on as electrical impulses (also called signals) to the billions of nerve cells (neurones) which make up the nervous system.
