The trigeminal nerve controls the muscles of mastication. Chewing and swallowing would be very adversely affected.
What will be an ideal response?
There is an entrance to the auditory tube in the upper pharyngeal region, and contraction of the palatal muscles can pull on this opening. Therefore, repeated swallowing can open the auditory tube and allow the passage of air into or out of it to equalize the pressure on the middle ear caused by increasing or decreasing altitude or underwater pressure.
