QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (BRAND NEW!!)
1. Which cranial nerve is primarily responsible for sensory
innervation of the face and motor function for mastication?
a) Facial (VII)
b) Trigeminal (V)
c) Glossopharyngeal (IX)
d) Hypoglossal (XII)
Answer: b) Trigeminal (V)
Rationale: CN V (trigeminal) provides sensory to face and motor
to muscles of mastication. Facial (VII) is for facial expression;
glossopharyngeal (IX) for pharynx; hypoglossal (XII) for tongue
movement.
2. The space between the true vocal folds is called the:
a) Ventricle
b) Glottis
c) Epilarynx
d) Vallecula
1
,Answer: b) Glottis
Rationale: The glottis is the opening between the vocal folds.
Ventricle is a sinus above folds; epilarynx is upper larynx;
vallecula is space between epiglottis and tongue.
3. Which muscle is the primary abductor of the vocal folds?
a) Lateral cricoarytenoid
b) Thyroarytenoid
c) Posterior cricoarytenoid
d) Cricothyroid
Answer: c) Posterior cricoarytenoid
Rationale: Posterior cricoarytenoid is the only vocal fold
abductor; all others listed are adductors or tension adjusters.
4. The outer ear consists of which two structures?
a) Tympanic membrane and ossicles
b) Auricle and external auditory meatus
c) Cochlea and semicircular canals
d) Eustachian tube and round window
Answer: b) Auricle and external auditory meatus
Rationale: Outer ear = pinna (auricle) + ear canal. Tympanic
membrane is boundary of middle ear. Cochlea is inner ear.
2
,5. Which ossicle is attached to the oval window?
a) Malleus
b) Incus
c) Stapes
d) Stapedius
Answer: c) Stapes
Rationale: Stapes’ footplate fits into oval window of cochlea.
Malleus attaches to TM; incus connects malleus to stapes.
6. The organ of Corti is located in which structure?
a) Scala vestibuli
b) Scala tympani
c) Basilar membrane
d) Reissner’s membrane
Answer: c) Basilar membrane
Rationale: Organ of Corti sits on basilar membrane; contains
hair cells for hearing. Scala vestibuli/tympani are perilymph-
filled ducts.
7. What is the primary function of the Eustachian tube?
a) Amplify sound
b) Equalize middle ear pressure
3
, c) Transduce sound to neural signals
d) Produce cerumen
Answer: b) Equalize middle ear pressure
Rationale: Eustachian tube connects middle ear to nasopharynx,
balancing pressure with atmosphere. Amplification is ossicles’ job;
transduction is cochlea; cerumen from outer ear glands.
8. The tensor veli palatini muscle is innervated by CN:
a) V
b) VII
c) IX
d) X
Answer: a) V (trigeminal)
Rationale: Tensor veli palatini (palatal tensing) is innervated by
trigeminal; levator veli palatini is vagus (X).
9. Which laryngeal cartilage is shaped like a signet ring?
a) Thyroid
b) Arytenoid
c) Cricoid
d) Epiglottis
Answer: c) Cricoid
Rationale: Cricoid is ring-shaped with a broad lamina
