Chapter 10, Problem 18RQ
Summary Introduction
Introduction: A sense organ which supports the function of hearing is known as ear. An ear is divided into various parts which are external ear, middle ear and internal ear. Inside the ear, a canal which connects middle ear to the nasopharynx is known as Eustachian tube.

Fill in the blank:
The olfactory interpreting centers are located deep within the temporal lobes and at the base of the_______________________ lobes of the cerebrum.
Ototoxic drugs are drugs that may damage the cochlea, auditory nerve and/or the vestibular system of the ear. The damage caused is usually temporary and symptoms improve once the patient stops taking the drug. However, in some patients, the damage is permanent. Damage to the cochlea is the most common problem associated with these drugs.
The reason that hearing loss results when the cochlea is damaged is:
Select one:
a. The bones in the ear do not amplify or increase the sound vibrations.
b. The eardrum cannot transmit vibrations from sound waves to the malleus.
c. The Eustachian tube remains open.
d. Hair cells within the damaged cochlea do not bend preventing the transmission of an electrical signal to the auditory nerve.
Within the auditory system different regions of the ______________ vibrate in response to sounds of varying________________
a
tympanic membrane; amplitude
b
basilar membrane; amplitude
c
tympanic membrane; frequencies
d
basilar membrane; frequencies
