It arises from the inferior half of the medial surface of the lamina of the thyreoid cartilage, close to its ventral angle, and also from the lateral part of the conus elasticus. The muscular fibres pass dorsally and upwards to be inserted into the lateral border and muscular process of the arytsenoid cartilage ; some of the fibres, however, turn round this cartilage and become continuous with the arytsenoideus obliquus. The upper fibres of the thyreo-arytaenoideus vary very greatly in their development and arrangement. By its action the muscle, rotates the arytsenoid cartilage and draws it ven- trally in such a way that its vocal pro- cess is carried ventrally and medially and the vocal fold is rendered somewhat flaccid. The muscle thus antagonises the crico-thyreoideus. The main action of the muscle must, however, be that of a constrictor of the supraglottic region of the larynx. 69.
