![]() The inferior fibers are horizontal and continuous with the circular fibers of the esophagus the rest ascend, increasing in obliquity, and overlap the Constrictor medius. The pharyngeal constrictor muscles are drained of blood by the pharyngeal venous plexus, which drains into the internal jugular vv. From these origins the fibers spread backward and medialward to be inserted with the muscle of the opposite side into the fibrous raphé in the posterior median line of the pharynx. 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. The superior pharyngeal constrictor muscle is one of the pharyngeal constrictor muscles. On the thyroid cartilage it arises from the oblique line on the side of the lamina, from the surface behind this nearly as far as the posterior border and from the inferior cornu. Citation, DOI, disclosures and article data. From the cricoid cartilage it arises in the interval between the Cricothyreoideus in front, and the articular facet for the inferior cornu of the thyroid cartilage behind. These muscles are responsible for the initiation of swallowing and phonation. The Inferior constrictor (Constrictor pharyngis inferior) the thickest of the three constrictors, arises from the sides of the cricoid and thyroid cartilage. The vagus nerve innervates the majority of the muscles associated with the pharynx and larynx.
