The superior pharyngeal constrictor muscle is a quadrilateral muscle of the pharynx. It is the uppermost and thinnest of the three pharyngeal constrictors. [citation needed] The muscle is divided into four parts according to its four distincts origins: a pterygopharyngeal, buccopharyngeal, mylopharyngeal, and a glossopharyngeal part.
Superior constrictor muscle; Middle constrictor muscle; Inferior constrictor muscle; During swallowing, these muscles constrict to propel a bolus downwards (an involuntary process). The inner longitudinal layer includes: Stylopharyngeus muscle; Salpingopharyngeus muscle; Palatopharyngeus muscle; During swallowing, these muscles act to shorten ...
The palatopharyngeus (palatopharyngeal or pharyngopalatinus) muscle is a small muscle in the roof of the mouth. It is a long, fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the palatopharyngeal arch .
It is also known as Passavant's pad or palatopharyngeal ridge. The prominence of mucous tissue is formed by the contraction of superior constrictor during swallowing. Palatopharyngeus muscle originates from the upper surface of the palatal aponeurosis by anterior and posterior fascicle, which are separated by the insertion of levator veli ...
The pharyngeal branch ramifies upon reaching the superior border of the middle pharyngeal constrictor muscle. It is unclear whether the cranial root of accessory nerve (CN XI) [1] Sensory – pharyngeal branches of glossopharyngeal nerve. Sympathetic vasomotor – efferent fibres of the superior cervical ganglion.
The pharyngeal raphe is a raphe that serves as the posterior attachment for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). [1] [2] Two sides of the pharyngeal wall are joined posteriorly in the midline by ...
The levator veli palatini muscle elevates the soft palate during swallowing. This helps to prevent food from entering the nasopharynx. Its action may be slightly slower than its partner, the tensor veli palatini muscle. [1] It has little to no effect on the pharyngotympanic tube. [2]
