Cranial nerves and spinal nerves are part of which nervous system?

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

Answer: (D)

The main idea here is how the nervous system is organized by location. Cranial nerves and spinal nerves are outside the brain and spinal cord and serve as the link between the central nervous system and the rest of the body, which makes them part of the peripheral nervous system. The brain and spinal cord make up the central nervous system, where information is processed. The autonomic nervous system and the enteric nervous system are subdivisions that operate within the peripheral nervous system, handling involuntary functions and gut activity, respectively. But the key point for these nerves is that they lie outside the CNS, connecting it to the body, so they belong to the peripheral nervous system.
