D. the central nervous system and the peripheral nervous system

Explanation:

The nervous system is made up of the central nervous system and the peripheral nervous system.The central nervous system, in turn, is made of the brain which controls all the body activities and the spinal cord. The peripheral nervous system, on the other hand, contains the cranial and spinal nerves and connects the central nervous system to the rest of the body.Electrical impulses are carried from the sense organs such as the skin by the nerves to the brain which then interprets the stimulus and sends a response to the organs such as muscles and glands.
