The main parts of the brain include the cerebrum, the cerebellum and the brain stem.

The brain stem extends underneath the brain and is responsible for respiration and regulating body function. Two other parts of the brain, the pituitary gland and hypothalamus control certain types of hormone production and body temperature.
