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.

Trachea is also known as the windpipe. It is a tube about 10-12.5 cm long (4-5 inches) and about 2.5 cm wide (1 inch). The trachea extends from the lower edge of the larynx downward into the thoracic cavity, where it splits into right and left bronchi. Rings of cartilage keep the airway open. Functions of the trachea: 1  to conduct air to and from the lungs; 2  to filter air;  to trap particles in mucus.
