CN IX (Glossopharyngeal Nerve) and CN X (Vagus Nerve)

•	Function
	These two nerves are combined because of their close relationship. Together they control the sensory and motor innervation to the pharynx.
•	Assessment
	Gag or swallow reflex – elicited by manipulating the caudal aspect of the throat NOTE: Gloves should be worn, as rabies cannot be excluded in cases with swallowing defects. A history or notation during the observation portion of the exam of dysphagia or excessive salivation may be noted.
