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.
