Glossoepiglottic Folds
The anterior and lingual surface of the epiglottis is curved and is
covered on its cranial free part by mucous membrane, which is reflected
onto the sides and root of the tongue, forming a "medial" and two "lateral
glossoepiglottic folds." The lateral folds are partly attached to the wall
of the pharynx. The depressions between the epiglottis and the root of the
tongue, on either side of the medial fold, are called the "valleculae."
