The human brain is a highly complex organ that can be divided into several major regions, each with specific functions:
- Brainstem: Regulates vital functions such as breathing, heart rate, and sleep.
- Cerebellum: Coordinates movement, balance, and posture.
- Diencephalon: Includes the thalamus (relay center for sensory information) and hypothalamus (regulates hormones and homeostasis).
- Cerebrum: The largest part of the brain, responsible for higher cognitive functions, sensory processing, and voluntary movement.
