Which term describes nerves and ganglia extending from the brain and spinal cord?

• A. Peripheral Nervous System
• B. Central Nervous System
• C. Enteric Nervous System
• D. Cranial and Spinal

Answer: (A)

The peripheral nervous system is the network that lies outside the brain and spinal cord, consisting of nerves and ganglia that extend from the CNS to the rest of the body. It includes the nerves that reach limbs and organs, carrying signals to and from the brain and spinal cord. The central nervous system is just the brain and spinal cord themselves, not the extending nerves. The enteric nervous system sits within the walls of the gastrointestinal tract as its own nervous network, not the nerves that extend from the CNS. So, the description matches the peripheral nervous system.
