SEM of hair cells (brown/ pink) in a healthy inner ear. The inner ear converts sound waves into nerve impulses by stimulation of stereocilia (pink, upper frame), projections at the ends of the hair cells. Waves entering the inner ear displace the fluid that surrounds the stereocilia, causing the stereocilia to bend. This bending causes the hair cells to release neurotransmitter chemicals, which generate nerve impulses that travel to the brain along the auditory nerve.
