Functions?

The Nervous System controls all of your body’s actions and functions.

It senses changes not only within your body but also outside of it in your environment and enables you to respond within fractions of a second

Structure…

There are two main divisions of the nervous system 1. The central nervous system(CNS) 2. The peripheral nervous system (PNS)

The PNS gathers information from outside and inside the body.

The CNS receives and analyzes this info and initiates a response.

The PNS then picks up and carries the response signals
