The salpingopharyngeus is known to raise the pharynx and larynx during deglutition (swallowing) and laterally draws the pharyngeal walls up. In addition, it opens the pharyngeal orifice of the pharyngotympanic tube during swallowing. This allows for the equalization of pressure between the auditory canal and the pharynx. The salpingopharyngeus is innervated by the vagus nerve (CN X) via the pharyngeal plexus. musculus salpingopharyngeus SCTID:244807009 UBERON:0010937 FMA:46665 salpingopharyngeus UMLS:C1521985 Salpingopharyngeus is a muscle that attaches to pharyngotympanic tube and the pharynx and is innervated by pharyngeal plexus of CN X and participates in oral/pharyngeal behaviors.[FEED] digestive system element lateral structure
