It is normally pointed upward during breathing with its underside functioning as part of the pharynx, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its superior side functioning as part of the pharynx. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is at the back. The glossopharyngeal nerve (CN IX) sends fibers to the upper epiglottis that contribute to the afferent limb of the gag reflex. The superior laryngeal branch of the vagus nerve (CN X) sends fibers to the lower epiglottis that contribute to the efferent limb of the cough reflex.

What triggers the epiglottis to move?
The epiglottis is triggered to move by the act of swallowing. When we swallow, the epiglottis closes over the trachea to prevent food and liquids from entering the airway, directing them instead to the esophagus.

What stops the epiglottis working?
The epiglottis may stop working properly due to conditions like epiglottitis, which is inflammation of the epiglottis usually caused by an infection.

What structure covers the epiglottis?
During swallowing, the epiglottis covers the glottic opening to prevent aspiration of food or fluids into the lungs.
What structure closes off the entrance to the larynx and trachea which prevents food or liquid from entering the respiratory system?

Why would move downward to close the trachea during swallowing?
