More Information
The epiglottis is a leaf-shaped flap of cartilage located at the root of the tongue. During swallowing, it folds back to cover the entrance of the larynx, directing food and liquid into the esophagus instead of the trachea.
Tips
A common mistake is confusing the epiglottis with other anatomical structures in the throat such as the larynx or pharynx. Remember that the epiglottis specifically acts as a flap that covers the larynx during swallowing.
