Practice Examination –Questions with Answers
& Detailed Rationales 2026 Updated | 100%
Correct - Utica College

Question 1
Which cranial nerve is responsible for the sense of smell?
• A) CN II – Optic
• B) CN I – Olfactory
• C) CN VIII – Vestibulocochlear
• D) CN V – Trigeminal
• E) CN VII – Facial
Answer: B) CN I – Olfactory
Rationale: Cranial Nerve I (Olfactory) is responsible for the sense of smell. It is a
sensory nerve that carries smell information from the nasal mucosa to the brain.
Testing involves asking the patient to identify familiar smells with eyes closed.


Question 2
Which cranial nerve is responsible for vision?
• A) CN I – Olfactory
• B) CN II – Optic
• C) CN III – Oculomotor
• D) CN IV – Trochlear
• E) CN V – Trigeminal
Answer: B) CN II – Optic

Rationale: Cranial Nerve II (Optic) is responsible for vision. It is a sensory nerve
that carries visual information from the retina to the brain. Testing involves visual
acuity using a Snellen chart and visual field assessment.


Question 3
Which cranial nerve controls eye movement, pupil constriction, and
accommodation?
• A) CN II – Optic
• B) CN III – Oculomotor
• C) CN IV – Trochlear
• D) CN VI – Abducens
• E) CN V – Trigeminal
Answer: B) CN III – Oculomotor
Rationale: Cranial Nerve III (Oculomotor) controls most eye movements, pupil
constriction, and accommodation. It innervates the medial, superior, inferior rectus
muscles and the inferior oblique muscle, as well as the levator palpebrae
superioris.


Question 4
Which cranial nerve controls downward and inward eye movement?
• A) CN III – Oculomotor
• B) CN IV – Trochlear
• C) CN VI – Abducens
• D) CN II – Optic
• E) CN V – Trigeminal
Answer: B) CN IV – Trochlear
Rationale: Cranial Nerve IV (Trochlear) controls downward and inward
movement of the eye. It innervates the superior oblique muscle. It is the smallest
cranial nerve and the only one that exits from the dorsal aspect of the brainstem.

Question 5
Which cranial nerve is responsible for facial sensation and chewing?
• A) CN VII – Facial
• B) CN V – Trigeminal
• C) CN IX – Glossopharyngeal
• D) CN X – Vagus
• E) CN XII – Hypoglossal
Answer: B) CN V – Trigeminal
Rationale: Cranial Nerve V (Trigeminal) is responsible for facial sensation and
mastication (chewing). It has both sensory (face, mouth, cornea) and motor
(muscles of mastication) components. Testing involves assessing facial sensation
and jaw clenching.


Question 6
Which cranial nerve controls lateral eye movement?
• A) CN III – Oculomotor
• B) CN IV – Trochlear
• C) CN VI – Abducens
• D) CN II – Optic
• E) CN V – Trigeminal
Answer: C) CN VI – Abducens
Rationale: Cranial Nerve VI (Abducens) controls lateral eye movement by
innervating the lateral rectus muscle. Damage to this nerve results in the inability
to abduct the eye (lateral gaze).

Question 7
Which cranial nerve is responsible for facial expressions and taste (anterior two-
thirds of the tongue)?
• A) CN V – Trigeminal
• B) CN VII – Facial
• C) CN IX – Glossopharyngeal
• D) CN X – Vagus
• E) CN XII – Hypoglossal
Answer: B) CN VII – Facial
Rationale: Cranial Nerve VII (Facial) controls facial expressions (motor) and taste
from the anterior two-thirds of the tongue (sensory). Testing involves asking the
patient to smile, frown, puff out cheeks, and identify tastes.


Question 8
Which cranial nerve is responsible for hearing and balance?
• A) CN VII – Facial
• B) CN VIII – Vestibulocochlear
• C) CN IX – Glossopharyngeal
• D) CN X – Vagus
• E) CN XII – Hypoglossal
Answer: B) CN VIII – Vestibulocochlear
Rationale: Cranial Nerve VIII (Vestibulocochlear) is responsible for hearing
(cochlear component) and balance (vestibular component). Testing involves the
Weber and Rinne tests for hearing and assessment of balance and nystagmus.


Question 9
Which cranial nerve is responsible for swallowing and taste (posterior one-third of
the tongue)?
