What does the CNS not include?

The central nervous system (CNS) does not include the peripheral nervous system (PNS), which consists of all the nerves and ganglia outside the brain and spinal cord. The CNS is primarily made up of the brain and spinal cord, responsible for processing and transmitting information throughout the body. In contrast, the PNS connects the CNS to limbs and organs, facilitating communication between the CNS and the rest of the body.
