What function do the malleus, incus, and stapes bones in the inner ear play in processing sounds?
A.
The bones transform pressure waves into nerve impulses that the brain recognizes as sound.
B.
The bones equalize pressure between the middle ear and the atmosphere.
C.
The bones transmit vibrations to the oval window setting the fluid in the cochlea in motion.
D.
The bones depolarize or hyperpolarize hair cells depending on the direction they vibrate.
Which statement is accurate about the cochlear duct?
a. It detects linear acceleration of the head when the otolithic membrane bends the hair cells.
b. It is filled with perilymph.
c. It contains hair cells that convert sound waves into nerve signals.
d. It contains a spiral organ that rests on a vestibular membrane.
Where are the auditory receptors, known as hair cells? A. In the auditory nerve B. Along the basilar membrane of the cochlea C. Between the incus and the stapes D. In the pinna
