Nervous System

Your nervous system is your body’s command center. It’s made up of your brain, spinal cord and nerves. Your nervous system works by sending messages, or electrical signals, between your brain and all the other parts of your body.

These signals tell you when to breathe, move, speak and see. Your nervous system keeps track of what’s going on inside and outside of your body and decides how to respond to any situation that you’re in. Your nervous system regulates complicated processes like thoughts and memory.

It also plays an essential role in the things your body does without thinking, like blushing, sweating and blinking.
