The primary function of the central nervous system (CNS) is to process and integrate sensory information and coordinate bodily responses. Comprising the brain and spinal cord, the CNS serves as the control center for the entire body, enabling communication between various systems. It is responsible for higher cognitive functions, reflexes, and the regulation of vital processes. The CNS's complex interactions with the peripheral nervous system facilitate voluntary and involuntary actions, ensuring the organism can adapt and respond to its environment effectively.
