Passavant cushion

The Passavant cushion is a small prominence in the posterior pharynx, formed from a focal bulge of the superior pharyngeal constrictor muscles during swallowing.

The "cushion" opposes the soft palate during the act of swallowing and is part of the seal between soft palate and pharynx that prevents nasopharyngeal reflux.
