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.
This leaves a membranous wall at the back, without cartilage. The trachealis muscle connects the ends of the incomplete rings and contracts during coughing, reducing the size of the lumen of the trachea to increase the rate of air flow.The esophagus lies posteriorly to the trachea.his is the only complete ring, the others being incomplete rings of reinforcing cartilage. The trachealis muscle joins the ends of the rings and these are joined vertically by bands of fibrous connective tissue, the annular ligaments of trachea. The epiglottis closes the opening to the larynx during swallowing.
