In addition to this extrinsic ligament, the epiglottis is connected to the tongue by the three glossoepiglottic folds of mucous membrane, which may also be considered as extrinsic ligaments of the epiglottis. The hyoepiglottic ligament {ligameutmn hyoepiglotticum) is an elastic band, which extends from the anterior surface of the epiglottis, near its apex, to the upper border of the body of the hyoid bone. The cricotracheal ligament (ligameiitum cricotracheale) connects the cricoid cartilage with the first ring of the trachea. It resembles the fibrous membrane which connects the cartilaginous rings of the trachea. Intrinsic Ligaments.—^The ligaments connecting the thyroid cartilage to the cricoid are three in number—the cricothyroid membrane and the two capsular ligaments. The Cricothyroid Membrane (conus elasticus) (Figs. 891 and 901) is composed mainly of yellow elastic tissue. It consists of three parts, a central triangular portion and two lateral portions. The central part (ligamentum cricothyreoideiim mediuvi) is thick aiid strong, narrow above and broaden- ing out below. It connects the contiguous margins of the thyroid and cricoid cartilages. It is convex, concealed on each side by the Cricothyroid muscle, but subcutaneous in the middle line; it is crossed horizontally by a small anas- tomotic arterial arch, formed by the junction of the two cricothyroid arteries. The lateral portions are thinner and lie close under the mucous membrane of the larynx. They extend from the superior border of the cricoid cartilage to the inferior margin of the true vocal cords with which they are continuous. Th
