Muscles allow your body to move and bend. There are muscles inside and outside of your body. Muscles are made of fibres made up of long thin cells packed in bundles. Inside of your muscles there are nerves which carry messages to and from the brain. There are also blood vessels which carry energy that your muscles need and they also carry away waste that your muscles are finished using. Muscles need to keep moving to stay healthy and strong. You can help your muscles stay strong and healthy by exercising every day.
