Question

A patient’s uvula rises midline when she says ""ahh"" and she has a positive gag reflex. The nurse has just tested which cranial nerves?

Answer 1

Answer:

The nurse tested craneal nerves IX and X

Explanation:

The cranial nerve IX is responsible for the movement of the uvula and the gag reflex. This nerve innervates the back of the tongue and the stylopharyngeus muscle.

The X nerve, also called the vagus nerve, controls the muscles that produce sounds with the soft palate, it innervates the larynx and pharynx muscles with the exception of the stylopharyngeus muscle.
