3 lut 2023 · It inserts posteriorly onto the pharyngeal raphe. Action: Constricts the wall of the pharynx during swallowing to propel the food bolus downwards. Innervation: Vagus nerve; Blood Supply: Pharyngeal branch of ascending pharyngeal artery with contributions from the tonsillar branch of facial artery.
The middle pharyngeal constrictor originates from the greater cornu and lesser cornu of the hyoid bone, and the stylohyoid ligament. It inserts onto the pharyngeal raphe. It is innervated by a branch of the vagus nerve through the pharyngeal plexus.
30 paź 2023 · The middle pharyngeal constrictor muscle proximally attaches to the stylohyoid ligament and the greater and lesser cornu of the hyoid bone. It distally attaches to the median pharyngeal raphe, as does the inferior pharyngeal constrictor muscle.
Action: Swallowing. Description: The Middle constrictor (Constrictor pharyngis medius) is a fanshaped muscle, smaller than the preceding. It arises from the whole length of the upper border of the greater cornu of the hyoid bone, from the lesser cornu, and from the stylohyoid ligament.
25 maj 2024 · The superior constrictor inserts onto the pharyngeal tubercle of the skull base and the pharyngeal raphe, a midline tendinous seam where the constrictor muscles converge. Contraction of this muscle narrows the upper pharyngeal segment and closes the nasopharynx during swallowing.
superior, middle, and inferior constrictor muscles create the tubular pharynx and join in a posterior midline raphe. The superior pharyngeal constric-tor muscle has complex attachments to the buc-cinator muscle, the mandible, and the tongue base. From the pharyngeal wall, the stylopharyn-geus muscle extends up to the styloid process of
