Which nervous system covers all nerve impulses outside the central nervous system?

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

Answer: (B)

The peripheral nervous system is the part of the nervous system that includes all nerves outside the brain and spinal cord, and it is responsible for transmitting sensory information to the central nervous system and carrying motor commands from it. This means every impulse traveling between the body and the central nervous system passes through the peripheral nerves. The central nervous system stays within the brain and spinal cord, so it isn’t the system outside the CNS. The enteric nervous system is a specialized network within the gut, a subset of peripheral nerves but not the whole outside-CNS network. The autonomic nervous system is a division of the peripheral system that controls involuntary functions, but there are also somatic nerves for voluntary actions, so it doesn’t cover all impulses. So the correct choice is the peripheral nervous system.
