1. What is the primary function of the outer ear?
A. Convert sound into electrical impulses
B. Collect and funnel sound toward the eardrum
C. Maintain balance
D. Produce auditory nerve signals
Correct Answer: B. Collect and funnel sound toward the
eardrum
Rationale: The pinna and ear canal collect sound and direct it
toward the tympanic membrane.
2. Which structure separates the outer ear from the middle
ear?
A. Cochlea
B. Ossicles
C. Tympanic membrane
D. Eustachian tube
Correct Answer: C. Tympanic membrane
Rationale: The tympanic membrane, or eardrum, forms the
boundary between the external and middle ear.
3. Which three bones make up the middle-ear ossicular chain?
A. Malleus, incus, and stapes
,B. Cochlea, utricle, and saccule
C. Pinna, canal, and tympanum
D. Vestibule, cochlea, and semicircular canals
Correct Answer: A. Malleus, incus, and stapes
Rationale: These three ossicles transmit and amplify
mechanical vibrations from the eardrum toward the inner ear.
4. Which ossicle is attached directly to the tympanic
membrane?
A. Stapes
B. Incus
C. Malleus
D. Cochlea
Correct Answer: C. Malleus
Rationale: The malleus receives vibrations from the tympanic
membrane and transfers them to the incus.
5. The stapes transmits vibration primarily to the:
A. Round window
B. Oval window
C. Ear canal
D. Tympanic membrane
Correct Answer: B. Oval window
Rationale: The footplate of the stapes is connected to the oval
window, transmitting vibration into the cochlea.
6. What is the main sensory organ responsible for hearing?
A. Cochlea
,B. Semicircular canals
C. Eustachian tube
D. Pinna
Correct Answer: A. Cochlea
Rationale: The cochlea contains sensory structures that convert
mechanical vibrations into neural signals.
7. Which cells are primarily responsible for converting
mechanical sound energy into neural signals?
A. Hair cells
B. Red blood cells
C. Schwann cells
D. Platelets
Correct Answer: A. Hair cells
Rationale: Cochlear hair cells transduce mechanical movement
into electrical signals used by the auditory system.
8. The auditory nerve carries information from the cochlea to
the:
A. Stomach
B. Brain
C. Eardrum
D. Middle-ear muscles
Correct Answer: B. Brain
Rationale: The auditory portion of cranial nerve VIII carries
auditory information from the inner ear to the central nervous
system.
, 9. What is the unit commonly used to describe the frequency
of a sound?
A. Decibel
B. Hertz
C. Pascal
D. Volt
Correct Answer: B. Hertz
Rationale: Hertz (Hz) represents cycles per second and is used
to express frequency.
10. What does decibel level primarily describe?
A. Frequency
B. Sound level or intensity
C. Ear-canal length
D. Wavelength only
Correct Answer: B. Sound level or intensity
Rationale: Decibels are used to express sound pressure or level
using a logarithmic scale.
11. A higher-frequency sound is generally perceived as:
A. Louder
B. Softer
C. Higher in pitch
D. Lower in pitch
Correct Answer: C. Higher in pitch
Rationale: Frequency is closely related to perceived pitch;
higher frequency generally corresponds to higher pitch.
