The soft palate is moveable, consisting of muscle fibers sheathed in mucous membrane. It is responsible for closing off the nasal passages during the act of swallowing, and also for closing off the airway. During sneezing, it protects the nasal passage by diverting a portion of the excreted substance to the mouth.
The pharyngeal muscles (involuntary skeletal) push food into the esophagus. There are two muscular layers of the pharynx: the outer circular layer and the inner longitudinal layer. The outer circular layer includes: Superior constrictor muscle; Middle constrictor muscle; Inferior constrictor muscle
As soon as a bolus of food is received in the pharynx, elevator muscles relax, and the pharynx descends. The inferior pharyngeal constrictor muscle, along with the other constrictors, contract upon the bolus, and convey it downward into the esophagus. [4] [7] During swallowing, they contract and cause peristalsis in the pharynx. [4]

“Most kids are going to go through having strep throat, getting a scrape on their knee, having the flu without ever having any subsequent problems,” Lima says. “In the grand scheme of things ...
The muscle closes the rima glottidis, adducting (approximating) the apices of the vocal process to close the ligamentous part of rima glottidis (in which it is synergystic with the oblique arytenoid muscles and transverse arytenoid muscle). [1] It thus functions to close the airway. [citation needed] It also shortens and slackens the vocal ...
