PATHOLOGY

Detailed explanation-1: -The central nervous system includes the brain and spinal cord. The peripheral nervous system includes the nerves that run throughout the whole body.

Detailed explanation-2: -A stimulus from any part of the body is always carried to the brain or spinal cord for the correct response. A response to a stimulus is also generated in the central nervous system. Therefore, the brain and the spinal cord are called the central nervous system.

Detailed explanation-3: -Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.
