The ______________________________, known as the “stirrup,” is one of the auditory ossicles of the
middle ear. It plays a key role, with the malleus and incus, in transferring vibrations from the
tympanic membrane to the oval window to facilitate hearing.
The ______________________________ funnels sound waves. It consists of the auricle and the external
acoustic meatus. It is the outermost section of the ear.
The ______________________________ is a spiral-shaped structure of the inner ear that looks like a
shell. When it receives movement from the three auditory ossicles, fluid inside it moves. These
fluid waves move hair cells, which activates nervous system receptors. Signals travel to the brain,
where they are interpreted as sound.
The ______________________________ is a passageway from the bottom of the concha to the tympanic
membrane. It forms an S-shaped curve.
The ______________________________ contains fluid-filled canals that contribute to hearing and
balance. It’s the innermost part of the ear and contains two types of labyrinths: A bony labyrinth
with a series of cavities, including the semicircular canals and the vestibule, and a membranous
The ______________________________ contains three auditory ossicles, the malleus, incus, and stapes.
The ______________________________, known as the “hammer,” is one of the auditory ossicles of the
middle ear. It plays a key role in transferring vibrations from the tympanic membrane to the incus
to facilitate hearing.
