The human nervous system is a system of nerves that begins in the brain and is part of every area of your body from your fingertips to your eyes, from the skin on your toes to your bones, tendons and ligaments. The nervous system is designed to help humans perceive the world around them and to keep them safe. A simple example of the human nervous system is when your finger or hand gets too close to a heat source and you instinctively pull back. Your brain and nerve endings feel the heat and signal your muscles to retract your hand. Teaching the human nervous system is a big job. It's a complicated system that can be difficult to teach.
