Laryngeal cavity. The laryngeal central cavity is tubular in shape and lined with mucosa. The superior aspect of the cavity (laryngeal inlet) opens into the pharynx, inferior and posterior to the tongue. The inferior aspect of the cavity is continuous with the lumen of the trachea.The laryngeal cavity may be divided into 3 major regions: the vestibule, the middle, and the infraglottic space. The vestibule is the upper portion of the cavity, in between the laryngeal inlet and the vestibular folds.he inferior aspect of the cavity is continuous with the lumen of the trachea.

The epiglottis is a structure found in the throat. Specifically, it's located behind the tongue and above the larynx. Elastic cartilage forms this thin, teardrop-shaped flap. A mucous membrane coats the epiglottis.The side facing the mouth is covered in cells similar to those in the rest of the mouth, whereas the backside is covered with cells resembling those of the larynx. The epiglottis is held in place by two ligaments.he esophagus delivers food to the lower digestive system whereas the larynx is the passageway for air to enter the lungs. To prevent food or drink from getting into the lungs, the epiglottis moves to cover the larynx when swallowing. This movement is accomplished by muscles reacting to contact with food or drink.
