In a man, if abducens nerve is injured then which one of the following functions will be affected?

• A. Movement of eye ball
• B. Swallowing
• C. Movement of the tongue
• D. Movement of the neck

Answer 1

The correct option is A Movement of eye ball

Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for contracting the lateral rectus muscle to abduct (i.e., turn out) the eye. The inability of an eye to turning outward results in a convergent strabismus or esotropia of which the primary symptom is a double vision or diplopia in which the two images appear side-by-side.
