What is gag reflex?
The pharyngeal reflex, commonly referred to as the gag reflex, is an uncontrollable response that causes the soft palate to rise and the bilateral pharyngeal muscles to tighten. The posterior pharyngeal wall, the tonsil region, or the base of the tongue can all be stimulated to cause this reaction. The gag reflex is thought to be an evolutionary reaction that emerged as a means of preventing choking and swallowing foreign items.
