Brain

The brain is the part of the body which lets animals make sense of things.
It gets input from sense organs, and changes behaviour in response to this information.
In humans, the brain also controls our use of language, and is capable of abstract thought.
The brain is the main control centre of the whole body.

Your brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation.
A complicated highway system of nerves connects your brain to the rest of your body, so communication can occur in split seconds.
