The CNS includes

• A. Brain and Spinal Cord
• B. Nerves
• C. Ganglia
• D. Autonomic System

Answer: (A)

The central nervous system is the brain and spinal cord, acting as the main processing and command center of the nervous system. The brain interprets sensory information, governs thought and memory, and directs voluntary and reflexive actions, while the spinal cord routes signals between the brain and the body and can coordinate simple reflexes on its own. Signals to and from the CNS travel via nerves, which are bundles of axons located in the peripheral nervous system. Clusters of neuron cell bodies in the peripheral nervous system are called ganglia, and the autonomic system—responsible for involuntary functions like heart rate and digestion—also resides in the peripheral nervous system. So, the brain and spinal cord make up the CNS.
