The nervous system is made up of the spinal cord, the brain and nerves. The nervous system is the body’s control system. The nervous system is one of the most important systems in your body because it sends, receives, and processes information and commands sent by your body in the form of nerve impulses.
Nerve impulses tell your body’s muscles and organs how to respond to things and what to do. The nervous system is made up of two main parts: the central nervous system and the peripheral nervous system.

The peripheral nervous system is all the nerves and nervous structures that branch off of the brain and spinal cord, or are not in the brain or spinal cord. The peripheral nervous system carries impulses from the central nervous system to muscles and various parts throughout the body.

Nervous tissue is made up of two types of cells: neurons and glial cells. Neurons are the cells that send nerve messages. Neurons are made up of three parts: the cell body, dendrites, and axons. The autonomic nervous system is the part of the nervous system that is in charge of involuntary actions such as heart beats and digesting food.
