Origin: Medial pterygoid plate, pterygomandibular raphé, alveolar process Insertion: Pharyngeal raphe, pharyngeal tubercle Nerve: Vagus nerve Action: Swallowing Description: The Superior constrictor (Constrictor pharyngis superior) is a quadrilateral muscle, thinner and paler than the other two. Velopharyngeal closure is accomplished through the contraction of several velopharyngeal muscles including the levator veli palatini, musculus uvulae, superior pharyngeal constrictor, palatopharyngeus, palatoglossus, and salpingopharyngeus. Velopharyngeal closure is accomplished through the contraction of several velopharyngeal muscles including the levator veli palatini, musculus uvulae, superior pharyngeal constrictor, palatopharyngeus, palatoglossus, and salpingopharyngeus. 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 various purposes, including speech. These muscles contribute to either a palatal or a pharyngeal component of velopharyngeal closure. The velopharyngeal mechanism consists of a muscular valve that extends from the posterior surface of the hard palate (roof of mouth) to the posterior pharyngeal wall and includes the velum (soft palate), lateral pharyngeal walls (sides of the throat), and the posterior pharyngeal wall (back wall of the throat). superior pharyngeal constrictor, and salpingopharyngeus. Understanding the normal anatomy and physiology of the velopharyngeal mechanism is the first step in providing appropriate diagnosis and treatment for children born with cleft lip and palate. These findings suggest that the superior pharyngeal constrictor muscle may also play an important role in the expression of smooth coordinated movements. Function Innervation Superior pharyngeal constrictor Pulls pharyngeal. This action facilitates the act of deglutition by pushing the bolus inferiorly, into the esophagus and stomach. These muscles make up the inner layer of musculature - they act to elevate (shorten and widen) the pharynx and larynx during swallowing and speaking.

The main function of the superior pharyngeal constrictor is the constriction of the upper part of the pharynx. superior pharyngeal constrictor muscle middle pharyngeal constrictor muscle inferior pharyngeal constrictor muscle Inner/longitudinal muscles. ![]()
