Eustachian Tube
Theeustachian tube(pharyngotympanictube) connects the middle ear cavity with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx. Opening and closing functions of theeustachian tubeare physiologically and pathologically important.
