The central nervous system is made up of two main parts; the spinal chord and the brain. It is the center of the entire nervous system and is in charge of processing all the information received from the peripheral nervous system (Biology Online). The central nervous system also sends out messages to the peripheral nervous system, sometime unconsciously (Biology Online).external image moz-screenshot-2.jpgexternal image moz-screenshot-3.jpgexternal image moz-screenshot-4.jpgexternal image moz-screenshot-5.jpgexternal image 19588.jpg
