Which term refers to the nervous system outside the CNS that connects it to the rest of the body?

• A. Peripheral nervous system
• B. Central nervous system
• C. Autonomic nervous system
• D. Sensory nervous system

Answer: (A)

The peripheral nervous system is the network that lies outside the brain and spinal cord and connects them to the rest of the body. It includes all the nerves that reach into limbs and organs, carrying sensory information back to the brain and sending motor commands out to muscles and glands. This system allows your body to respond to touch, temperature, pain, and other stimuli, and to carry out actions like moving a hand or adjusting organ function. That’s why it’s the best fit: it names the entire set of nerves outside the central nervous system that link it to the body. The central nervous system refers to the brain and spinal cord themselves. The autonomic nervous system is a subdivision within the peripheral system that controls involuntary functions, not the whole outside-CNS network. The sensory nervous system describes pathways for sensing information and is part of the peripheral system but does not name the entire outside-CNS network.
