PRESENTATION OUTLINE
Your nervous system directs your body to respond to information.
The nervous system makes you aware of your surroundings and without it you could not move, think, or sense the world around you.
There are two responses your nervous system does: voluntary and involuntary. The voluntary responses are the responses that you can control like throwing a ball or dancing around your kitchen. The involuntary responses are the responses that your body does itself like breathing and sweating.
