Set 6, for October 20, 2000 Cataracts: normal version compared to vision with cataracts How the Ear Works I: sound waves enter the ear canal and vibrate against the tympanic membrane. How the Ear Works Part II: Sound passes through the tympanic membrane, vibrates the tiny bones of the ear, and is translated to a nerve impulse through the cochlea. The cochleus, in turn, sends sound impulses to the temporal lobe of the brain. The ear is also responsible for the sense of balance, which occurs within the vestibular apparatus. The vestibular apparatus translates information about the body's position to the brainstem.
