In a man, abducens nerve is injured. Which one of the following functions will be affectedThe abducens nerve is the sixth cranial nerve. It is a motor nerve.
It supplies the lateral rectus muscle of the eye ball, which turns the eye outward (abduction).
If it is injured, the eye cannot be turned outward and tends to be pulled inward, causing a squint and double vision.
So the function affected is the movement of the eye ball.
Swallowing is controlled by the glossopharyngeal and vagus nerves, the neck muscles by the spinal accessory nerve, and the tongue by the hypoglossal nerve.
