The part of the brain which helps to maintain body balance.

The cerebellum is at the back of the brain, below the cerebrum. Its size is 1/8^th of Cerebrum. But it's a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together). Because of your cerebellum, you can stand upright, keep your balance, and move around.

Whenever a person consumes alcohol the first part of the brain to be affected is one’s cerebellum. That’s why a person loses its control after drinking.
