What is the Nervous System: The nervous system is made up of “billons of two way communcation nerve cells in the body”- (infomration in quotations from the book The complete Human body volume 2 by Professor Alice Roberts).The Nervous system is seperated into two systems; The central nevous which is made up of the brain and spinal cord,the other system is the periphel nervous system whicn is made up of the nervous and bundles of fibers which are commonly called axons.How the system works: The two parts of the nervous system both work in different ways,The spinal cord is the part of the system which obtains the signals given by the muscles,joints and the skin of the body, another job it is responsible for is carrying the nerves which are in charge of contolling all movement in the body. The brain is commonly considered the most complex part of the nervous system , the job of the brain is to collect the signals given of by the ears, mouth ,nose and the eyes and the rest of the body which are given off from the spinal cord.
