The vestibular system conveys a sense of motion and gravity. Anatomically, it consists of the labyrinths as specific receptors located in the inner ear, and the vestibular nuclei in the brain stem. Information about motion is also conveyed by the visual system and other sensory systems. The vestibular system therefore, in a sense, constitutes a subsystem of motion sense. The labyrinth consists of three semicircular canals and the otoliths (Fig. 1).
