Which symptom is indicative of damage to Cranial Nerve VI?

Damage to Cranial Nerve VI, also known as the abducens nerve, is primarily associated with issues related to eye movement. This cranial nerve is responsible for innervating the lateral rectus muscle, which controls the abduction of the eye, allowing it to move laterally. When the abducens nerve is compromised, patients may experience diplopia, which is double vision that occurs when the eyes are not properly aligned. Additionally, medial strabismus, which refers to an inward turning of the eye, can result from the inability to abduct the affected eye due to weakness of the lateral rectus muscle.

The presence of both diplopia and medial strabismus indicates a specific dysfunction of the eye's muscle control that is directly related to the loss of function of Cranial Nerve VI. Other options relate to different cranial nerves altogether, which manage functions such as taste sensation, neck muscle strength, and salivary production, thereby ruling them out as indicative of damage to Cranial Nerve VI.
