ear1
noun
The ear of a mammal is composed of three parts. The outer or external ear consists of a fleshy external flap and a tube leading to the eardrum or tympanum. The middle ear is an air-filled cavity connected to the throat, containing three small linked bones that transmit vibrations from the eardrum to the inner ear. The inner ear is a complex fluid-filled labyrinth including the spiral cochlea (where vibrations are converted to nerve impulses) and the three semicircular canals (forming the organ of balance). The ears of other vertebrates are broadly similar
