How do you functions of the CNS and the PNS differ?

The central nervous system (CNS), comprising the brain and spinal cord, is responsible for processing and integrating sensory information, coordinating bodily functions, and facilitating higher cognitive functions such as thinking and decision-making. In contrast, the peripheral nervous system (PNS) consists of nerves outside the CNS that connect the brain and spinal cord to the rest of the body, facilitating communication between the CNS and limbs or organs. While the CNS acts as the control center, the PNS functions as the relay system, transmitting signals to and from the CNS to enable bodily responses.
