What are the 2 main anatomical parts of the nervous system?

The two main anatomical parts of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS comprises the brain and spinal cord, responsible for processing and integrating information. The PNS includes all the nerves that branch out from the CNS, connecting it to the rest of the body and facilitating communication between the CNS and peripheral organs. Together, they coordinate sensory input and motor output, enabling bodily responses to stimuli.
