What is epiglottis vallecula?

The epiglottis is a small flap of cartilage at the base of the tongue that prevents food and liquid from entering the trachea during swallowing. The vallecula is a small depression or fossa located between the root of the tongue and the epiglottis. The vallecula serves as a reservoir for saliva and is an important landmark during some medical procedures, such as endotracheal intubation. Together, the epiglottis and vallecula play a critical role in protecting the airway during swallowing and other activities that involve the mouth and throat.
