Seymour Simon has written over 200 award-winning science books about animals, anatomy, astronomy, earth science, and vehicles! Six tiny muscles hold each eyeball steady in the sockets of your head. The ears contain the three smallest bones in the body: the hammer, anvil, and stirrup. In addition to hearing, ears help you to keep your balance. Without the brain, we wouldn’t be able to see or hear.
