Anatomical structure. Normally, the larynx is located in the anterior lateral wall of the larynx. It is the widest part of the larynx and is connected by a wide isthmus to the thyroid gland. The mucous membrane of the epiglottis is represented by stratified squamous epithelium with a large number of receptors and glands that secrete mucus. The submucosal base is loose, lymphoid tissue is absent. The lamina propria is rich in loose connective tissue and contains venous nodes. The muscle layer is loose, has a well-defined fibrillar plate, consisting of elastic fibers that intertwine with the fibers of skeletal muscle tissue
