Ans: The vestibular hair cells are divided into two types:Type I, these are thinner and goblet in shape. Type II, these are columnar types.The hair cells are the primary sensory receptors present in the ear that converts mechanical stimuli into electrical signals. Both types of hair cells are present in the central and peripheral zones of all the five organs of the vestibular system. The semicircular canals use these hair cells to detect the movement of fluids along with the stereocilia.
