The ear consists of the external ear canal, middle ear, and inner
ear. The middle ear is separated from the ear canal by the eardrum. The middle
ear contains the malleus, incus, and stapes, which are also known as the
hammer, anvil, and stirrup. The inner ear contains the cochlea, which is the
main sensory organ of hearing. The eustachian tube runs from the middle ear to
the back part of the nose.
