How does the nervous system send messages and how does it receive it?

The central nervous system (CNS) is composed of the brain and the spinal cord. The central nervous system communicates with the rest of the body by sending messages from the brain through the nerves that branch off of your spine. You are able to move your body, get out of bed, drive to work, play tennis, and so on, when your mind’s intention to move is translated by the brain into neurochemicals and electrical impulses. The chemical and electrical impulses, through contractions of your skeletal muscles, result in the movement of your body.

In addition to simple muscular activity, your CNS plays a complex role in the orchestration of the mind-body-spirit connection by way of its connection with the chemical messenger system (CMS) and the autonomic nervous system (ANS). This complex interaction is called the brain neuromatrix.
