It was found that the histology as well as the ultrastructure of the secretory product of these gland cells varied depending upon the location of the glands in the airway. For this reason, the glands of the epiglottis, larynx and trachea have been described separately. Epiglottal glands ...

On the contrary, in adult subjects degenerated taste buds can be found and their number usually increases with age. Sometimes such pictures can be observed also in young animals. The probable functional role of chemoreceptors located on the laryngeal surface of the epiglottis has been examined. ...
Food and fluids from the pharynx usually are prevented from entering the larynx by the epiglottis, a thin, leaflike tissue. The “stem” of the leaf attaches to the front and top of the larynx. When a person is breathing, the epiglottis is held in a vertical position, like an open trap...
