text: According to the NASA website : "The ear is made up of several smaller structures that can be organized into three distinct anatomical regions: an outer ear which extends from outside the body through the ear canal to the tympanic membrane ( ear drum ), a middle ear, an air-filled cavity containing three tiny bones (ossicles) that transmit and amplify sound between the ear drum and the cochlea (where the sense of hearing is located); and the inner ear, composed of the cochlea and the vestibular system.
