A patient presents to the emergency department because of a brief very sharp pain in their cheek. The patient states that the pain seems to be unpredictable, but often happens when brushing their teeth. The pain usually lasts less than a minute but sometimes has lasted up to 10 minutes. The pain usually occurs just anterior to the ear and on the posterior aspect of the temporal region. Based on the patient’s symptoms, which nerve is mostly likely affected?
a. Facial
b. Maxillary
c. Greater auricular
d. Mandibular
e. Ophthalmic
d. Mandibular
When administering a corneal reflex test (blink reflex test), the doctor lightly touches the patient’s right cornea with a piece of cotton. When this happens, the patient closes both of their eyes, which indicates a normal response and nothing is wrong with the patient’s corneal reflex. Which nerve is responsible for the efferent end of the corneal reflex test?
a. Trigeminal
b. Oculomotor
c. Abducens
d. Trochlear
e. Facial
e. Facial

When performing sensory testing over the entire head, it is determined that there is a lack of sensation to the skin directly superficial to the parotid gland. Which nerve is injured to cause this lack of sensation?
a. Greater auricular n.
b. Facial n.
c. Trigeminal n.
d. Lesser occipital n.
e. Greater occipital n.
a. Greater auricular n.
Blockage of which of the following arteries would directly cause loss of vision or blindness in the corresponding eye?
a. Lacrimal a.
b. Central retinal a.
c. Supratrochlear a.
d. Anterior ethmoidal a.
e. Anterior ciliary a.
b. Central retinal a.
Disruption of the external carotid artery would cause decreased blood flow in all of the following arteries EXCEPT:
a. Occipital a.
b. Supraorbital a.
c. Superficial temporal a.
d. Posterior auricular a.
e. Mental a.
b. Supraorbital a.
A patient presents to their physician because of facial asymmetry. Over the past 2 days, they have noticed weakness of their facial muscles on the right side of their face. They are having difficulty smiling or blinking their right eye. When asking the patient to smile, the right side of their smile does not occur. The nerve that is injured passes through which opening?
a. Foramen rotundum
b. Foramen ovale
c. Jugular foramen
d. Stylomastoid foramen
e. Superior orbital fissure.
d. Stylomastoid foramen
After waking up one morning, a person realized they have double vision. In addition, they have complete ptosis (complete drooping of upper eyelid) of the right eye, as well as a right eye that is looking downward laterally (when trying to look straight forward) with a fully dilated right pupil. What nerve is affected?
a. Oculomotor
b. Trigeminal
c. Abducens
d. Trochlear
e. Facial
a. Oculomotor
If a patient presents with the right eye looking medially when trying to look forward, which nerve is most likely affected?
a. Oculomotor
b. Trigeminal
c. Abducens
d. Trochlear
e. Facial
c. Abducens
On physical examination, it is noticed that the patient’s right eye is constricted, the right eyelid is slightly drooped, and they are unable to sweat on the right side of their face. What is the most likely location of the lesion?
a. Oculomotor n.
b. Cervical sympathetic trunk
c. Parasympathetic root of the ciliary ganglion
d. Nasociliary n.
e. Facial n.
b. Cervical sympathetic trunk
During an MMA match, a fighter is punched in the face and gets a black eye. After imaging, it is known that the medial wall of the orbit has been blown out. Which sinus would you expect to see blood draining into?
a. Frontal
b. Lateral nasal
c. Maxillary
d. Mandibular
e. Ethmoidal
e. Ethmoidal
During a physical exam, the physician administered a pupillary light reflex test. The right eye has a normal reaction and constricts when light is shined into each eye; however, the left eye is unreactive each time. Because of this, it is determined that the deficit is in the efferent nerve supply to the pupillary constrictor muscle of the left eye. Which nerve is most likely injured?
a. Oculomotor n.
b. Optic n.
c. Trigeminal n.
d. Facial n.
e. Cervical sympathetic ganglion
a. Oculomotor n.
