    Fig. 215. The superior ligament or false chord (/?,) has an arched direction, and is much more slender than the inferior liga- ment. It is attached in front to the receding angle of the thyroid cartilage, and behind to the projection of the upper part of the front of the arytoenoid cartilage. The inferior ligament or true chord (^) is horizontal in direction, being attached in front to the receding angle of the thyroid cartilage below the superior ligament, and be- hind to the prominent anterior angle of the base of the arytsenoid cartilage. The interval between the two true vocal chords is the rima glotfidis. The Arteries of the larynx are derived from the superior and infe- rior thyroid arteries. The superior laryngeal artery^ derived from the superior thyroid, enters the larynx through the thyro- hyoid membrane, and divides into ascending and descending branches which suppl3^ the muscles and mucous membrane. The inferior laryngeal artery, derived from the inferior thyroid artery, reaches the back of the cri- coid cartilage and anastomoses with the superior artery.
