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.

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

C. Abducting and depressing the eye

D. Viewing close objects

E. Adducting the eye

Question 9

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
