<P> The vestibular system of the inner ear is responsible for the sensations of balance and motion . It uses the same kinds of fluids and detection cells ( hair cells ) as the cochlea uses , and sends information to the brain about the attitude , rotation , and linear motion of the head . The type of motion or attitude detected by a hair cell depends on its associated mechanical structures , such as the curved tube of a semicircular canal or the calcium carbonate crystals ( otolith ) of the saccule and utricle . </P>
