. Elements of human physiology. Physiology. ^—- Fig. 206.—Side view of cartilages of larynx, th, thyroid cartilage; ar, arytsenoid cartilage; cr, cricoid cartilage ; ctm, crico-thyroid muscle ; cli, vocal cords. Fig. 207.—Back view of larynx, arytsenoid muscle with the oblique fibres which pass round to join the arytseno-epiglottidean muscles ; ca-p. posterior crico-arytsenoid muscles. The lateral crico-arytcenoid runs upwards and backwards from the middle third of the upper border of the cricoid cartilage to the anterior margin of the base of the arytsenoid cartilage. The arytcenoid is a single flat muscle running horizontally between the posterior borders of the two arytsenoid cartilages. The thyro-arytanoid muscles run from the internal surface of the thyroid cartilage, close to the angle, backwards, to be inserted into the lateral border of the arytsenoid cartilage, the most internal fibres being contained in the vocal cords, and inserted into the processus vccalis of the arytsenoid. The false vocal cords are two ridges of mucous membrane, lying over and parallel to the true vocal cords, and separated from them by a lateral recess known as the ventricle of the larynx. During ordinary respiration the glottis or opening between the vocal cords remains about half open, being rhythmically widened with every inspiration. For the production of voice, the free borders of the vocal cords must be brought so near.
