The salpingopharyngeus is known to raise the pharynx and larynx during deglutition ( swallowing ) and laterally draws the pharyngeal walls up.
2.
The pharynx is pulled upwards and forwards by the suprahyoid and longitudinal pharyngeal muscles stylopharyngeus ( IX ), salpingopharyngeus ( pharyngeal plexus IX, X ) and palatopharyngeus ( pharyngeal plexus IX, X ) to receive the bolus.
3.
The actions of the levator palatini ( pharyngeal plexus IX, X ), tensor palatini ( Vc ) and salpingopharyngeus ( pharyngeal plexus IX, X ) in the closure of the nasopharynx and elevation of the pharynx opens the auditory tube, which equalises the pressure between the nasopharynx and the middle ear.
