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.

[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.

[6] It opens the pharyngeal orifice of the Eustachian tube during swallowing allowing for the equalization of pressure between the it and the pharynx.
