Your nerves system controls and cordinate many things that happen in your body.It acts as a central command post, collecting and processing information and making sure appropriate information gets sent to all parts of the body. These tasks are accomplished by two subdivisions of the nerves system, the central nervous system and the peripheral nervous system.
