Function

**__Function:__**
The nervous system controls everything you do, including breathing, walking, thinking, and feeling.

The Nervous system is like a network that releases messages back and forth to different parts of the body it does this through the spinal cord, which it runs from the brain down through the spinal cord and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message down the spinal cord, to the arm muscles telling your hand to pull away. This happens very quickly.

Neurons (nerves) are very thin some are small and some can be 3 feet long. All are shaped like flat stars which have varing degrees.
