- Superior pharyngeal constrictor
The superior pharyngeal constrictor muscle is one of the pharyngeal constrictor muscles. Its primary action is constriction of the pharynx (in coordination with the middle pharyngeal constrictor and the inferior pharyngeal constrictor muscles) to deliver a bolus of food into the esophagus.
Summary
- origin: pterygoid hamulus, pterygomandibular raphe and mandible
- insertion: pharyngeal raphe
- artery: ascending pharyngeal artery, branch of the external carotid artery
- nerve: pharyngeal plexus
- action: constriction of the pharynx, facilitating swallowing
