Which consists of the brain and spinal cord?

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

Answer: (A)

The brain and spinal cord make up the central nervous system. This system acts as the control center, processing incoming information, coordinating actions, and integrating responses. The rest of the nervous system, outside the CNS, is the peripheral nervous system, which carries signals to and from the brain and spinal cord. The autonomic nervous system is a division of the peripheral nervous system that governs involuntary functions like heart rate and digestion. The enteric nervous system is a network within the gut that can operate somewhat independently but is not the brain and spinal cord itself. Since the brain and spinal cord together form the CNS, this is the best answer.
