The central nervous system is made up of which structures?

Explanation:
The central nervous system is made up of the brain and spinal cord, which serve as the body’s main processing and command centers for interpreting information and directing actions. The other structures listed are part of the peripheral nervous system: cranial nerves and spinal nerves extend from the brain and spinal cord to the rest of the body, peripheral nerves carry signals to muscles and organs, and ganglia along the spine are collections of nerve cell bodies outside the CNS. So the correct answer identifies brain and spinal cord as the CNS.
