Question

Quizplus · Accepted Answer

The pharyngotympanic tubes, also known as Eustachian tubes, connect the middle ear to the nasopharynx, which is the upper part of the pharynx behind the nasal cavity. When we swallow, yawn or sneeze, the muscles in the pharynx contract, opening the Eustachian tubes, allowing air to enter the middle ear and equalize pressure. If the tubes are blocked, such as during a cold, pressure may build up in the middle ear, causing pain and temporary hearing loss.
