Which structures comprise the Central Nervous System?

• A. Autonomic ganglia
• B. Nerves outside CNS
• C. Brain and spinal cord
• D. Sensory receptors in skin

Answer: (C)

The brain and spinal cord form the central nervous system, serving as the main processing and control center that integrates sensory information and coordinates actions and higher functions like thought and memory. These structures are protected within the skull and the vertebral column and are distinct from the peripheral nervous system. Structures outside the CNS, such as autonomic ganglia, nerves that lie outside the brain and spinal cord, and sensory receptors in the skin, belong to the peripheral nervous system. They relay information to and from the CNS but are not part of the CNS itself.
