UWDA: Organ with organ cavity which connects the cavity of the middle ear to the cavity of the pharynx. Examples: There are only two pharyngotympanic tubes, the right and the left pharyngotympanic tubes.,MSH: A narrow passageway that connects the upper part of the throat to the TYMPANIC CAVITY.,CSP: tube that connects the pharynx to the middle ear space allowing for equalization of pressure across the eardrum.,FMA: Organ with organ cavity which connects the cavity of the middle ear to the cavity of the pharynx. Examples: There are only two pharyngotympanic tubes, the right and the left pharyngotympanic tubes.,NCI: A tubular structure that runs from the middle ear to the nasopharynx and is approximately 3-4 cm length. Its lumen is roughly triangular and has average diameter of 2-3 mm. The lumen is lined by ciliated pseudostratified, columnar epithelium, which sweeps material from the middle ear to the nasopharynx. It is functionally collapsed at rest, with slight negative pressure present in the middle ear, an
