Which structure is part of the Central Nervous System?

• A. Brain and spinal cord
• B. Peripheral nerves
• C. Autonomic ganglia
• D. Spinal nerves only

Answer: (A)

The central nervous system consists of the brain and spinal cord. These structures act as the main processing and control center, integrating sensory information, planning actions, and coordinating responses. The peripheral nervous system, which lies outside the brain and spinal cord, includes all the nerves that connect the CNS to the rest of the body. This includes peripheral nerves that carry signals to and from the CNS, autonomic ganglia that regulate involuntary functions, and spinal nerves that branch out to reach muscles and organs. Because of this distinction, the brain and spinal cord are the parts that belong to the CNS.
