Description

On the lateral wall of the nasal part of the pharynx is the pharyngeal ostium of the auditory tube, somewhat triangular in shape, and bounded behind by a firm prominence, the torus tubarius (cushion), caused by the medial end of the cartilage of the tube which elevates the mucous membrane. A vertical fold of mucous membrane, the salpingopharyngeal fold, stretches from the lower part of the torus; it contains the Salpingopharyngeus muscle.

A second and smaller fold, the salpingopalatine fold,stretches from the upper part of the torus to the palate.
