Pharyngeal reflex these reflexes is triggered) for both the pharyngo-upper esophageal sphincter contractile reflex and reflexive pharyngeal swallowing is increased. Pharyngeal reflex The pharyngeal reflex, gag reflex, or laryngeal spasm, is a reflex contraction of the back of the throat, evoked by touching the roof of the mouth, the back of the tongue, the area around the tonsils, the uvula, and the back of the throat.
