The superior pharyngeal constrictor contract to narrow its lumen to assist with bolus transport as well as seal the nasopharynx to prevent food from going up the middle and inferior pharyngeal constrictors contract to narrow its lumen to assist with bolus transport. They are innervated by the pharyngeal branch of the vagus nerve (CN X) with the exception of the stylopharyngeus muscle which is innervated by the glossopharyngeal nerve (CN IX).Pharynx Dr.N.Mugunthan.M.S., we have 15 Pics about Pharynx Dr.N.Mugunthan.M.S., like Inferior pharyngeal constrictor: Attachments and action | Kenhub, Muscles of the pharynx and their functions | Kenhub and also Dysphagia and odynophagia due to pharyngeal diverticulum | Kenhub. These constrictor muscles originate from bones and cartilage anteriorly and insert posteriorly to a tendinous seam called the pharyngeal raphe. The muscle is described in Grey’s Anatomy text as a large quadrilateral muscle that arises from four heads of origin (see Figure 1). There are two muscular layers of the pharynx: the outer circular layer and the inner longitudinal layer.ĭuring swallowing, these muscles constrict to propel a bolus downwards (an involuntary process).ĭuring swallowing, these muscles act to shorten and widen the pharynx. The superior pharyngeal constrictor muscle is an unusual skeletal muscle in that it is very dynamic and complex in function.
The pharyngeal muscles (involuntary skeletal) push food into the esophagus. After an independent reading, the final MR imaging score was designated by 2. Methods: 54 patients with locally advanced OPC were evaluated after intensity-modulated radiotherapy. Radiation dose to constrictor muscles plays an important role.
The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity. The following 5-point scale scoring system was used for the assessment of the status of the pharyngeal constrictor muscle: 1, normal constrictor 2, bulging constrictor 3, thinning constrictor 4, obscured constrictor 5, tumor protrusion into the parapharyngeal fat. Background and objective: Patients with oropharyngeal carcinoma (OPC) often have difficulty swallowing, which may affect quality of life (QoL).
