Pharyngeal raphe

The pharyngeal raphe is a raphe that serves as the origin and insertion for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). Two sides of the pharyngeal wall are joined together posteriorly in the midline by the raphe. Its superior part is attached to the pharyngeal tubercle; it extends inferiorly to the level of vertebra C6 where it blends with the posterior wall of the esophagus.
