Die dabei entstehende Verdickung der Pharynxwand wird auch Passavant'scher Ringwulst genannt. Er verhindert das Eindringen von Nahrungsbestandteilen in die hinteren Abschnitte der Nasenhöhle .
The superior pharyngeal constrictor muscle is the thinnest of the pharyngeal constrictors and is roughly quadrilateral. It originates from the pterygoid hamulus of the sphenoid bone, the posterior aspect of the pterygomandibular raphe, the mylohyoid line of the mandible, and the lateral aspect of the tongue (Standring, 2016; Tubbs, Shoja and ...

El constrictor faríngeo inferior, el más grueso de los tres constrictores, surge de los lados del cartílago cricoides y tiroideo. De manera similar a los músculos constrictores faríngeos superiores y medios , está inervado por el nervio vago (nervio craneal X), específicamente, por ramas del plexo faríngeo y por ramas neuronales del nervio laríngeo recurrente .
