The pharyngeal external wall is made up of four muscles: the superior pharyngeal constrictor, the middle pharyngeal constrictor, the inferior pharyngeal constrictor, and the stylopharyngeus. The three paired inner pharynx muscles work together to elevate the larynx, shorten the pharynx, and act during swallowing and speaking.
The stylopharyngeus, palatopharyngeus, and salpingopharyngeus are the names of these muscles. The pharyngeal muscles, which consist of an outer circular layer and an interior longitudinal layer, form the lumen of the pharynx. The superior, middle, and inferior pharyngeal constrictor muscles make up the outer circular layer. The pharynx connects the nasal passages to the oesophagus and larynx.
