The Nervous System
Your ability to process and react to all that happens around you is based on your nervous system. Information taken in by your body is sent through nerves to your brain or spinal cord where a reaction is determined. The reaction is then returned to your body through more nerves. How you feel something soft, smell fresh baked cookies, see your way home, hear someone call your name, taste something sour, and even breathe are all processes controlled by your nervous system. Anyone who has been startled knows that this process happens extremely fast!
Your nervous system consists of many nerves that are connected to all
parts of your body and is divided into two main systems: your central
nervous system consisting of your spinal cord and your
brain, and your peripheral nervous system that includes all the nerves
extending from your central nervous system and connecting to your skin,
muscles, and internal organs.
