    • n epiglottis A valve-like organ which helps to prevent the entrance of food and drink into the larynx during deglutition. In man the epiglottis is of oblong figure, broad and round above, attached by its narrow base to the anterior angle of the upper border of the thyroid cartilage or Adam's-apple, and also to the hyoid or tongue-bone, and the tongue itself; its ligaments for these attachments are the thyro-epiglottic, hyo-epiglottic, and glosso-epiglottic, the latter three in number, forming folds of mucous membrane. The muscles of the epiglottis are three, the thyro-epiglottideus and the superior and inferior aryteno-epiglottideus. Its substance is elastic yellow fibrocartilage, covered with mucous membrane continuous with that of the fauces and air-passages. In its ordinary state, as during respiration, the epiglottis stands upon end, uncovering the opening of the larynx; during the act of deglutition it is brought backward so as to protect this orifice. Any similar structure in the lower animals receives the same name. See cuts under alimentary and month.
