The central nervous system comprises which structures?

The central nervous system is the body's main information-processing and control system, and it consists of the brain and spinal cord. These structures are housed within the skull and vertebral column and protected by meninges and cerebrospinal fluid, enabling them to integrate sensory input, coordinate movement, and regulate higher functions like thought and autonomic activity. The other structures listed—peripheral nerves, autonomic ganglia, and the enteric plexus—are part of the peripheral nervous system, which connects the CNS to the rest of the body.
