It arises from the lower part of the cartilage of the Eustachian tube,[1] and inserts into the palatopharyngeus muscle by blending with its posterior fasciculus.

It opens the pharyngeal orifice of the Eustachian tube during swallowing to allow for the equalization of pressure between it and the pharynx.

[3] The salpingopharyngeus muscle arises from the inferior portion of the cartilaginous part of the pharyngotympanic tube near its pharyngeal opening.

[5] The salpingopharyngeus muscle raises the pharynx and larynx during deglutition (swallowing) and laterally draws the pharyngeal walls up.
