What are the three main parts of the brain?

The three main parts of the brain are the cerebrum, cerebellum, and brainstem. The cerebrum is the largest part of the brain and is responsible for higher brain functions such as thought, action, and sensory processing. Within the cerebrum, there are areas that govern various functions, including voluntary movement, learning, and emotions.

The cerebellum, located under the cerebrum at the back of the brain, plays a crucial role in coordination, balance, and fine motor skills. It integrates sensory information and helps maintain posture and equilibrium.

The brainstem, which connects the brain to the spinal cord, is vital for regulating many automatic functions essential for survival, such as heartbeat, breathing, and reflexes. It is also involved in controlling the sleep-wake cycle and relaying messages between different parts of the brain.

While the other options contain important structures related to brain function, they are not categorized as the three main parts of the brain. The frontal, parietal, and occipital lobes are subdivisions of the cerebrum; the thalamus and hypothalamus are part of the diencephalon, and pons and medulla oblongata are components of the brainstem but
