superior constrictor การใช้

• The palatopharyngeal folds on each side of the pharynx are brought close together through the superior constrictor muscles, so that only a small bolus can pass.
• There is also the simultaneous approximation of the walls of the pharynx to the posterior free border of the soft palate, which is carried out by the palatopharyngeus ( pharyngeal plexus IX, X ) and the upper part of the superior constrictor ( pharyngeal plexus IX, X ).
