Your semicircular canals are three tiny, fluid-filled tubes in your inner ear that help you keep your
balance. When your head moves around, the liquid inside the semicircular canals sloshes
around and moves the tiny hairs that line each canal. These hairs translate the movement
of the liquid into nerve messages that are sent to your brain. Your brain then can tell your body how to stay balanced. If
you spin around and then stop, the liquid inside your semicircular canals moves awhile
longer and the hairs continue to send the message that you are spinning even though
you're not. That's why you feel dizzy after carnival or amusement park rides. Whoa!
