Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What nerve supplies motor fibers to the lateral rectus muscle which rolls the eye laterally?
A
Trigeminal
B
Trochlear
C
Abducens
D
Vestibulocochlear
Explanation: 

Detailed explanation-1: -The abducens nerve functions to innervate the ipsilateral lateral rectus muscle and partially innervate the contralateral medial rectus muscle (at the level of the nucleus-via the medial longitudinal fasciculus).

Detailed explanation-2: -Abducens nerve (CN VI) The abducens nerve innervates the lateral rectus muscle of the eye. It is responsible for lateral eye movements.

Detailed explanation-3: -The lateral rectus muscle abducts the eye and directs the gaze laterally in the horizontal plane. This action is assisted by the superior and inferior oblique muscles which also abduct the eyes among their other functions.

Detailed explanation-4: -What is abducens nerve? The abducens nerve, also called the sixth cranial nerve or cranial nerve 6, is a motor nerve that controls the lateral rectus muscle. This is an extraocular eye muscle that allows the eye to perform abduction. Abduction is an outward movement.
