Chapter 37 Ear and Hearing
1) Which of the following structures is NOT part of the external ear?
A) Auricle
B) Pinna
C) External acoustic meatus
D) Tympanic cavity
E) All of these structures are parts of the external ear.
2) Which of the following structures of the ear function(s) as (an) organ(s) in the sense of equilibrium?
A) Vestibule and semicircular ducts
B) Cochlea
C) Eustachian tube
D) Pinna
E) Bony labyrinth
3) The S-shaped tube of the ear is called the
A) auditory tube.
B) membranous labyrinth.
C) external acoustic meatus.
D) bony labyrinth.
E) tympanic cavity.
4) What is the function of the pharyngotympanic tube?
A) To transmit sound waves to the tympanic membrane
B) To drain endolymph into the pharynx
C) To equalize the pressure on both sides of the eardrum
D) To drain perilymph into the pharynx
E) To transmit sound waves to the spiral organ
5) Which of the following structures is NOT part of the bony labyrinth?
A) Cochlea
B) Tympanic membrane
C) Vestibule
D) Semicircular canals
E) All of these structures are part of the bony labyrinth.
6) The membranous labyrinth is the only portion of the inner ear that contains endolymph.
7) The tympanic cavity is a fluid-filled chamber in the middle ear.
8) Which of the following membranes acts as a rigid roof over the cilia of the hair cells of the spiral organ, causing the cilia to bend against it when sound waves are present?
A) Basilar membrane
B) Tympanic membrane
C) Cochlear membrane
D) Vestibular membrane
E) Tectorial membrane
9) Which of the following is NOT a chamber found in the cochlea?
A) Scala tympani
B) Vestibule
C) Cochlear duct
D) Scala vestibuli
E) All of these are chambers found in the cochlea.
10) Which of the following is NOT true of the Weber test?
A) This test can distinguish conduction or sensory deafness.
B) The test is performed by placing a vibrating tuning fork against the midline of the forehead.
C) If a person has conductive hearing impairment, the sound will be heard louder in the normal ear.
D) In the case of normal hearing, a person will hear the sound with equal loudness in both ears.
E) All of these are true of the Weber test.
11) In the Rinne test, when the sound of the tuning fork can no longer be heard through bone conduction, normal hearing is indicated if the sound can once again be heard through air conduction.
12) Which chamber of the inner ear receives sound waves directly from the oval window?
A) Cochlear duct
B) Scala media
C) Scala tympani
D) Vestibule
E) Scala vestibuli
13) Which membrane separates the cochlear duct from the scala tympani, and provides a surface on which the spiral organ rests?
A) Vestibular membrane
B) Tectorial membrane
C) Cochlear membrane
D) Basilar membrane
E) Tympanic membrane
14) Which of the following is NOT true of sound wave frequency?
A) Different sound wave frequencies are perceived as different degrees of loudness.
B) The units for sound wave frequency are hertz (Hz).
C) Different sound wave frequencies stimulate specific hair cells in certain portions of the spiral organ.
D) Sound wave frequency can be reported in waves per second.
E) All of these are true of sound wave frequency.
15) The inner ear contains the organs for both hearing and equilibrium.
