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