It narrows the rima liy draw- ing the arytenoid cartilages together (adduction). The ventricularis' lies in the lateral wall of the larjTix, covered by the lamina of the thyroid cartilage. It arises from the anterior part of the crico-thyroid membrane and the ventral border of the thyroid lamina.

The two preceding muscles close the rima glottidis and slacken the vocal cords. With the ar^-tenoideus transversus and crico-arjd:enoideus lateralis they form a sphincter which closes the entrance to the larynx.
