Parts of Brain and their Functions

The brain is a part of the Central Nervous System. The three parts of Brain; Cerebrum, Cerebellum, Medulla Oblongata; and their functions is given here:
Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
Brainstem (Medulla Oblongata): acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Spinal Cord is also a part of the Central Nervous System (CNS) and is the center of the Reflex Action. It connects a large part of the peripheral nervous system to the brain. Information (nerve impulses) reaching the spinal cord through sensory neurons are transmitted up into the brain.
