The inside of the ear is composed of an organ called the vestibular labyrinth. The vestibular labyrinth includes semicircular canals, which contain fluids and fine hairlike sensors that act as a monitor to the rotations of the head. An important structure in the inner ear includes the otolith organs that contain crystals that are sensitive to gravity. These crystals are responsible for sensitivity to head positions, and can also be dislocated, causing them to lodge inside one of the semicircular canals, which causes dizziness.
