1 As a pharyngeal constrictor muscle, it assists in the swallowing of food (bolus), conveying it downward into the esophagus. There are six pharyngeal muscles, which work together to push food into the esophagus: Superior pharyngeal constrictor muscle Middle pharyngeal constrictor. Its function is to pull the pharyngeal wall forward and to constrict the pharyngeal diameter. It is innervated by the IX accessory nerve and X vagus via the pharengeal plexus. 2 It is inserted into the median raphe of pharyngeal aponeurosis. The pharyngeal plexus lies within the external fascia of the pharynx 3 on the posterolateral wall of the pharynx in the retropharyngeal space 7. the pterygopharyngeal part, the buccopharyngeal part, the myolopharyngeal part, and the glossopharyngeal part. ![]() The superior pharyngeal constrictor is composed of four parts according to origin (pterygomandibular raphe), i.e. It is located above the other two pharyngeal constrictors, forming a tube beginning at the pterygomandibular raphe. of the three pharyngeal constrictors, this one is intermediate in both superior/inferior position. Morphoanatomically, the superior pharyngeal constrictor is relatively thin and pale. middle pharyngeal constrictor: lesser and greater horns of the hyoid bone and the inferior part of the stylohyoid ligament: midline pharyngeal raphe: constricts the pharyngeal cavity: vagus (X), via the pharyngeal plexus: ascending pharyngeal a. The other pharyngeal constrictors are the middle pharyngeal constrictor and the inferior pharyngeal constrictor. ![]() The superior pharyngeal constrictor is one of the three constrictor muscles of the pharynx. ( anatomy) The quadrilateral muscle in the pharynx, located superior to other pharyngeal constrictor muscles, arises from the pterygomandibular raphe, and inserts into the median raphe
