 Brain The structure of the human brain. At the back of the skull has the cerebellum, which coordinates reflex actions that control muscular activity. The medulla controls respiration, heartbeat, and blood pressure. The hypothalamus is concerned with instinctive drives and emotions. The thalamus relays signals to and from various parts of the brain. The pituitary gland controls the body’s hormones. Distinct areas of the large convoluted cerebral hemispheres that fill most of the skull are linked to sensations, such as bearing and sight, and voluntary activities such as movement
