In order to understand how you think, act, and react, it is important to understand your body’s
complex system of cells, organs, and chemicals. The nervous system is a network of cells that
carries information to and from all parts of the body.

central nervous system
. The central nervous system is made up of
, which interprets and stores information
and sends orders to muscles, glands, and organs, and
, which is the pathway
connecting the brain and the peripherals nervous system.

, which maintains body functions under
ordinary conditions and saves energy, and the
