What Are Nerves?


Say: nurvz

When it comes to your body, your brain runs the show. It tells you what to do and makes sure all your systems are go so you can breathe, move around, and use your senses.

But your brain needs to send messages or signals to the other parts of your body to make these things happen. That's where nerves come in. Your nerves are like a bunch of wires or cables that send signals to and from the brain. The brain uses nerves to communicate with everything from your heart to your toes.
