. Cunningham's Text-book of anatomy. Anatomy. LIGAMENTS OF THE LAKYNX. 1067 Arytenoid cartilage Muscular process Vocal process Eima glottidis parts, viz., one median and two lateral, all of which are directly continuous with each other, and differ only in the nature of their upper connexions. The median part (crico-thyreoid ligament) of the conus elasticus is strong, tense, and elastic. It is triangular in shape, and is attached by its broad base to the upper border of the arch of the cricoid cartilage, whilst its apex is fixed to the medial part of the lower border of the thyreoid cartilage (Fig. 845, p. 1063). It is pierced by minute apertures, and is crossed superficially by the crico-thyreoid branch of the superior thyreoid artery. The median part of the conus elasticus, therefore, closes, ventrally, the interval between the cricoid and thyreoid cartilages. The lateral part on each side presents very different connexions. It is not attached to the inferior border of the thyreoid cartilage, but slopes upwards and medially on the inner side of the thyreoid lamina, and thus diminishes materially the transverse or frontal width of the cavity of the larynx. Its attachments are very definite. Inferiorly it is fixed to the superior border of the cricoid cartilage immediately subjacent to the lining mucous membrane of the larynx; above it is directly continuous with the vocal ligament or supporting band of the vocal fold. This ligament, indeed, may be looked upon as constituting the superior thickened free border of the lateral part of the conus elasticus. Ventrally the lateral part of the conus elasticus is attached to the inferior half of the medial surface of the lamina of the thyreoid cartilage, close to the angle, and dor sally to the inferior border of the processus vocalis of the arytenoid cartilage. In contact with the outer surface of the lateral part of the conus elasticus, and separating it from the thyreoid lamina, are the lateral crico- arytenoid muscles; t
