(X) nucleus, which carries motor fibers via CN 9 and 10, is located in:

X = nucleus ambiguous

Medulla

8

(X) nucleus, which carries motor fibers via CN 11, is located in:

X = cervical accessory

Upper SC

9

Parasympathetic nerve fibers traveling in CN 3 originate in (X) nucleus in brainstem.

X = Edinger-Westphal

10

X = inferior salivary

12

Parasympathetic nerve fibers traveling in CN 10 originate in (X) nucleus in brainstem.

X = dorsal motor nucleus of X

13

Patient has hoarseness in voice and left-deviation of uvula on phonation. Which nerve damaged?

Right vagus

14

Carotid artery bifurcation occurs at level of which landmark in pharynx/larynx?

Superior border of thyroid cartilage

15

The afferent limb of gag reflex is a mediated by (X) branch of (Y) nerve. (Z) nerve mediates efferent limb of this reflex.

X = pharyngeal
Y = glossopharyngeal
Z = vagus

16

The pupillary light reflex involves (X) nerve as the afferent limb and (Y) nerve as the efferent limb

X = optic
Y = oculomotor

17

Ipsilateral slowness of the pupillary response to light is the first sign of (compression/lesion) in:

Compression of the oculomotor nerve
