Which option correctly describes the functional relationship between the central and peripheral nervous systems?
Answer and explanation
Correct answer: The central nervous system processes messages, while the peripheral nervous system carries messages to and from the body.
The central nervous system, consisting mainly of the brain and spinal cord, receives, processes, and coordinates information. The peripheral nervous system consists of nerves outside the brain and spinal cord; these nerves carry sensory messages toward the central system and motor commands away from it to muscles or glands. Therefore, option A correctly states the two-way functional relationship. The other options wrongly assign digestion, hormone production, plant functions, or blood filtration to these systems.
