Final answer:
The brain has three major parts: cerebrum, cerebellum, and brain stem, each with their own functions.
Step-by-step explanation:
The brain has three major parts: the cerebrum, cerebellum, and brain stem. The cerebrum is responsible for our highest mental capabilities and is divided into four primary lobes: frontal, temporal, occipital, and parietal. The cerebellum controls balance, coordination, movement, and motor skills. The brain stem, which includes the midbrain, pons, and medulla oblongata, is involved in unconscious autonomic functions and relays messages to other parts of the brain.
