Which nervous system component excludes the brain and spinal cord?

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

Answer: (B)

Think about how the nervous system is organized. The brain and spinal cord form the central nervous system, handling processing and signal integration. Everything outside those structures makes up the peripheral nervous system, which includes all the nerves that extend to the rest of the body. So the part that excludes the brain and spinal cord is the peripheral nervous system. The autonomic nervous system and the enteric nervous system are not separate from that idea; they’re both subdivisions of the peripheral nervous system. The autonomic system controls involuntary functions like heart rate and digestion, while the enteric system governs the digestive tract.
