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

Answer 1

The correct option is A Movement of the eye ball

Abducens (abducent) nerve is a cranial nerve which originated from the ventral surface of the medulla oblongata. It innervates the lateral rectal muscle of eye ball. It is a motor nerve and controls the movement of the eye ball. Hence, if abducens nerve is injured in man, movement of eyeball will be affected.
