Which nervous system consists of the brain and spinal cord?

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

Answer: (A)

The brain and spinal cord form a central nervous system, the body’s processing and command center. The brain interprets sensory input, stores memories, and plans actions, while the spinal cord acts as the main conduit for signals between the brain and the rest of the body and coordinates many reflexes. Outside the CNS lies the peripheral nervous system, consisting of nerves that reach through the body and include subsystems for automatic, involuntary functions and for voluntary control of muscles. So, the structure that consists of the brain and spinal cord is the central nervous system.
