When completing a neurological assessment, which cranial nerves are tested within the mouth?

A.

III, IV, VIII

B.

III, II, VI

C.

IX, X, XII

D.

I, I, III

Answer and Explanation

The Correct Answer is C

A. Cranial nerves III, IV, and VIII are not involved in mouth functions; they primarily deal with eye movements and hearing.


B. Cranial nerves III, II, and VI are involved in vision and eye movement but not in mouth functions.


C. Cranial nerves IX (glossopharyngeal), X (vagus), and XII (hypoglossal) are all tested through functions such as swallowing, speech, and movement of the tongue, which occur in the mouth.


D. Option D incorrectly lists cranial nerve I twice; cranial nerve I (olfactory) is related to the sense of smell, not the mouth.
