The salpingopharyngeus is a muscle of the pharynx. In addition to elevating the pharynx, this muscle also widens the Eustachian tube to help equalise the pressure in the middle ear. Attachments: Originates from the Eustachian tube and inserts onto the pharyngeal wall. Action: Elevation of the pharynx during swallowing. Innervation: Vagus nerve (CN X). Blood supply: Ascending palatine branch of facial artery, greater palatine branch of maxillary artery and the pharyngeal branch of ascending pharyngeal artery.
