The middle pharyngeal constrictor is a fanshaped muscle, smaller than the Inferior pharyngeal constrictor muscle.
Origin and insertion
It is inserted into the posterior median fibrous raphé, blending in the middle line with the muscle of the opposite side.
As soon as the bolus of food is received in the pharynx, the elevator muscles relax, the pharynx descends, and the constrictores contract upon the bolus, and convey it downward into the esophagus.
