Text, Questions & Answers

Did you know your body has a super speedy messenger? It's called the nervous system. Just like an email service, it sends messages from your brain to different parts of your body. The main workers in this network are the brain, the spinal cord, and lots of nerves. These messages help you do everyday things. Think about when you touch something hot. Your nerves send a message to your brain through the spinal cord, and the brain quickly tells your hand to pull away. All this happens faster than a lightning bolt!
