1. Which structure is primarily responsible for converting sound
waves into neural impulses?
A. Tympanic membrane
B. Ossicles
C. Cochlea
D. External auditory canal
Answer: C. Cochlea
Rationale: The cochlea contains the organ of Corti, where specialized
hair cells convert mechanical vibrations into electrical nerve impulses
that travel to the brain through the auditory nerve.
2. Which cranial nerve carries auditory information from the inner
ear to the brain?
,A. Cranial Nerve V
B. Cranial Nerve VII
C. Cranial Nerve VIII
D. Cranial Nerve X
Answer: C. Cranial Nerve VIII
Rationale: The vestibulocochlear nerve (Cranial Nerve VIII) transmits
hearing and balance information from the inner ear to the central
nervous system.
3. The smallest bones in the human body are located in the:
A. Nose
B. Wrist
C. Middle ear
D. Larynx
Answer: C. Middle ear
Rationale: The malleus, incus, and stapes are the smallest bones in the
body and amplify sound vibrations before they reach the inner ear.
, 4. Which speech subsystem generates airflow necessary for speech
production?
A. Articulatory system
B. Resonatory system
C. Respiratory system
D. Auditory system
Answer: C. Respiratory system
Rationale: The respiratory system provides the air pressure required to
produce voiced and voiceless speech sounds.
5. The vocal folds are located within the:
A. Pharynx
B. Oral cavity
C. Larynx
D. Trachea
Answer: C. Larynx
Rationale: The larynx houses the vocal folds, which vibrate during
phonation to create voiced sounds.
, 6. Which structure separates the oral and nasal cavities during
swallowing?
A. Tongue
B. Epiglottis
C. Soft palate (velum)
D. Uvula
Answer: C. Soft palate (velum)
Rationale: The soft palate elevates to close off the nasopharynx during
swallowing and for most speech sounds, preventing food or air from
entering the nasal cavity.
7. Which frequency range is generally most important for
understanding conversational speech?
A. 20–100 Hz
B. 500–4000 Hz
C. 6000–10000 Hz
D. Above 15000 Hz
Answer: B. 500–4000 Hz
