Larynx

(lar; -inks) [?i , larynx]. The organ of the voice situated between the trachea and the base of the tongue. It consists of a series of cartilages, the thyroid, the cricoid, and the epiglottis, and three pairs of cartilages, the arytenoids, and those of Sant or in i and Wrisberg, which are lined by mucous membrane, and are moved by the muscles of the larynx. The mucous membrane is, on each side, thrown into two transverse folds that constitute the vocal bands, the upper being the false, the lower the true vocal band. By the approximation or separation of the vocal bands the changes in the pitch of the voice are produced. The space between the vocal bands is termed the glottis. 356
