is the trachea posterior to the epiglottis
The mucosa of the larynx, which is continuous with that of the laryngopharynx and trachea, is loose except over the posterior part of the epiglottis and over the vocal ligaments. Hence this membrane may become raised abnormally by submucous fluid, as in edema of the larynx.3-9) is covered by mucous membrane to form the epiglottis. The epiglottis is situated posterior to the root of the tongue and the body of the hyoid bone and anterior to the inlet of the larynx. The inferior end, or stalk, of the leaf-shaped cartilage is anchored to the posterior aspect of the thyroid cartilage.
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.
