the malleus (the umbo is part of
the malleus), the incus, and the
stapes. The tympanic membrane
separates the external ear from
the middle ear and is composed of
the pars tensa. Ceru- men and
sebaceous glands lie outside the
middle ear; the semicircular
canals, vestibule, and cochlea lie in
the inner ear. The helix and
antihelix are parts of the auricle
ANS: C
Vibrations from the tympanic mem-
brane cause the delicate hair cells
of the organ of Corti to strike
against the membrane of Corti,
stimulating impuls- es in the
sensory endings of the audi- tory
division of the eighth cranial nerve.
ANS: A
The eustachian tube is a
cartilaginous and bony
passageway between the
