Nervous System

The function of the nervous system is to control the body so that we can survive.

-There are more nerve cells in the human brain than there are stars in the Milky Way.

- If we lined up all the neurons in our body it would be around 600 miles long.

- There are 100 billion neurons in your brain alone.

- A newborn baby's brain grows almost 3 times during the course of its first year.

- The left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body.

The nervous system maintains homeostasis by controlling and regulating the other parts of the body.

"In the same way that all of your cells need oxygen transported by the circulatory system, all of your tissues and organs require instruction and direction from the nervous system. There is obvious interaction between your muscles and your nervous system. That interaction helps you move around and interact with your environment." ~
