    pass forward converging, and are inserted into the angle of the thyroid cartilage. The inferior is the stronger, it is tendinous and horizontal ; the superior is membranous and semi-lunar. The narrow passage between these, as before stated, is the rima-glottidis. Between the superior and inferior ligament of each side is a fossa or cavity, semi-lunar in shape, which is named the sinus or ventricle of the larynx. Below the rima-glottidis, the larynx enlarges, and is of a circular figure, and soon terminates in the trachea, which afterwards bifurcates into the bronchi. The arteries which supply the larynx are derived from the superior and inferior thyroid; the former is a branch of the external carotid, the latter of the subclavian. The laryngeal nerves are four in number, two on each side, the superior and inferior; both are derived from the par-vagum or pneumo-gastrie. The inferior laryngeal nerve supplies the dilating muscles of the larynx, while the superior supplies those which close the glottis, and also the lining membranes.
