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 trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people.The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum).The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. A procedure called bronchoscopy is usually needed to remove a foreign body from the trachea. 2  Tracheal cancer: Cancer of the trachea is quite rare. 3  Symptoms can include coughing or difficulty breathing. 4  Tracheomalacia: The trachea is soft and floppy rather than rigid, usually due to a birth defect.
