There are a lot of things going on in your body right now. And perhaps the most important of them is your nervous system. Pinch yourself. There are a lot of nerves running through the area where you pinched your skin. When you pinched your skin, the nerves fired and sent information about the pain to your brain, which in turn notified you of the pain. All this happens in a millisecond, but the signal has a long way to go there and back. Have you ever wondered how the nervous system works? And why it’s so important? How about looking inside your body and finding out what your nerves do? The most important ones run all the way down your spine and into your brain. This big bundle of nerves, the central nervous system (or CNS), is responsible for everything you do. Can you believe it?
