Superior pharyngeal constrictor function12/5/2023 ![]() ![]() 1 As a pharyngeal constrictor muscle, it assists in the swallowing of food (bolus), conveying it downward into the esophagus. Middle constrictor overlaps the superior. Inferior constrictor overlaps the middle constrictor. ![]() Its function is to pull the pharyngeal wall forward and to constrict the pharyngeal diameter. Into the median fibrous raphe on the posterior aspect of pharynx. 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 pterygopharyngeal part, the buccopharyngeal part, the myolopharyngeal part, and the glossopharyngeal part. The pharynx, a tube-like structure, is a part of the digestive system and is composed of six muscles. The superior pharyngeal constrictor is composed of four parts according to origin (pterygomandibular raphe), i.e. The levator veli palatini (LVP) and the superior pharyngeal constrictor (SPC) influence velopharyngeal patency and soft palate position, but their behavior during respiration is incompletely characterized. It is located above the other two pharyngeal constrictors, forming a tube beginning at the pterygomandibular raphe. Conservative management Speech therapy improves velopharyngeal function when VPD is minimal or due to articulation errors and in postoperative patients. ![]() Morphoanatomically, the superior pharyngeal constrictor is relatively thin and pale. The function of the velopharyngeal mechanism is to create a tight seal between the velum and pharyngeal walls to separate the oral and nasal cavities for. The other pharyngeal constrictors are the middle pharyngeal constrictor and the inferior pharyngeal constrictor. Function The inferior pharyngeal constrictor muscle has a broad role in moving the lower part of the pharynx. The Superior constrictor (Constrictor pharyngis superior) is a quadrilateral muscle, thinner and paler than the other two. 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 The nasopharyngeal cavity opens into the cavity of the oropharynx through the pharyngeal isthmus, which lies between the posterior border of the soft palate and the posterior pharyngeal wall. ![]()
