Purpose

to transmit signals of various stimuli from nerve cells to the brain.
Central Nervous System

part of the nervous system consisting of the brain and spinal cord.


Brain

the body's "computer" in a way that holds information and controls all the systems in the body.


Brain Stem

connects the spinal cord, and in turn, the entire nervous system to the brain.


Spinal Cord

Connects to the nervous system and acts as one tube that connects to thousands of others, moving the right data to and from the right parts of the body.


Peripheral Nervous System
