Which is the network of nerves outside the CNS that relays information and controls actions?

• A. Peripheral Nervous System
• B. Central Nervous System
• C. Autonomic Nervous System
• D. Enteric Nervous System

Answer: (A)

The Peripheral Nervous System is the network of nerves outside the brain and spinal cord. Its job is to connect the central nervous system to the rest of the body, relaying sensory information from receptors to the brain and spinal cord and carrying motor commands from them to muscles and glands, which enables actions. Within the PNS, the somatic division handles voluntary movement and external sensation, while the autonomic division regulates automatic functions like heart rate and digestion. The enteric nervous system is a subdivision of the autonomic system that specifically manages the gut. Since the question refers to the overall network outside the CNS that both relays information and controls actions, the Peripheral Nervous System is the best fit.
