Question 3

A 35-year-old man presents to the emergency department with a fractured mandible after a bar fight. After the mandibular reconstruction surgery, the patient is noted to have loss of sensation in his lower lip.

Question 4

A 27-year-old mother presents to the pediatrics clinic with difficulty breastfeeding her new baby. She notes that her nipple becomes erect from stimulation from the baby, but milk does not come out. After an extensive workup, it is found that the mother’s hypothalamus is not producing adequate amounts of oxytocin. Identify the correct cellular target and function of oxytocin in a normal patient.

A. Alveolar cells, milk production

B. Myoepithelial cells, muscle relaxation

C. Myoepithelial cells, muscle contraction

D. Alveolar cells, muscle relaxation

E. Myoepithelial cells, milk production

Question 5

A 31-year-old woman undergoing surgery to resect a laryngeal tumor is having difficulty coming off the mechanical ventilator post operation. She was initially extubated in the operating room after the procedure, but showed immediate signs of respiratory distress and was thus re-intubated. After workup of the laryngeal musculature, it is noted that her vocal cords are stuck in the adducted position and she cannot provide any abduction. Which of the following muscles is most likely paralyzed, preventing abduction of the vocal folds?

A. Lateral crico-arytenoids

B. Thyro-arytenoids

C. Transverse arytenoids

D. Posterior crico-arytenoids

E. Cricothyroids

Question 6

A 45-year-old man presents with a chief complaint of progressive hearing loss and dizziness. His history reveals a long career in the boxing industry, in which he sustained many blows to the head over his lifetime. You fear that he has incurred some cell loss in certain areas of his brain. Which of the following areas of cell loss would explain your patient’s hearing difficulty?

A. Corti ganglion

B. Pterygopalatine ganglion

C. Vestibular (Scarpa) ganglion

D. Superior cervical ganglion

E. Otic ganglion

Question 7

A 63-year-old man presents with a thrombosis that is occluding his right external carotid artery. He displays symptoms of decreased blood flow to his right face, with an absent facial artery pulse in his right occipital region, the area behind his ear, his right temporal region, and the deep structures of the right face normally supplied by the maxillary artery. Based on the symptoms and vessels receiving decreased blood flow, where is the occlusion on the external carotid artery?

A. Superior to the maxillary artery

B. At the level of the ascending pharyngeal artery

C. Just below the facial artery

D. At the level of the occipital artery

E. At the bifurcation of the common carotid artery

Question 8

Cycloplegia is a condition in which the ciliary muscle is paralyzed, resulting in a loss of visual accommodation. Identify the condition in which a patient with cycloplegia would have the most difficulty seeing clearly.

A. Viewing objects at a distance

B. Abducting the eye

C. Abducting and depressing the eye

D. Viewing close objects

E. Adducting the eye

Question 9

An 83-year-old man suffers a stroke to the left facial motor nucleus of the pons, resulting in the paralysis of facial nerve. Which of the following motor deficits does he likely experience?

A. Mandible deviates to the left when the mouth is opened

B. Right corner of the mouth droops when smiling

C. Left corner of the mouth droops when smiling

D. Unable to wrinkle the forehead on the right side

E. Mandible deviates to the right when the mouth is opened

Question 10

A resident performing a neurological exam wants to test the pons. Identify the reflex most likely used.

A. Gag reflex

B. Corneal reflex

C. Vestibuloocular reflex

D. Accommodation reflex

E. Pupillary light reflex
