. Anatomy, descriptive and applied. Anatomy. 1164 THE ORGANS OF VOICE AND BESPIBATION above and called the pomum Adami {prominentia laryngea). This prominence is subcutaneous, is more distinct in the male than in the female, and is often separated from the integument by a bursa, the bursa subcutanea prominentiae laryngeae. The anterior borders of the alse of the thyroid cartilage which are continuous below are separated above by a V-shaped notch, the thyroid notch {incisura thyroidea superior). The posterior borders are free, rounded, and somewhat thickened, and are extended in the form of superior and inferior cornua. The Older surface of each ala (Fig. 891) presents an oblique ridge {linea obliqua), which passes downward and forward from a tubercle situated near the root of the superior cornu, the superior tubercle (tuberculum. thyroideum superitis), to a small tubercle near the anterior part of the lower border, the inferior tubercle (tuberculum thyroideum' inferius). This ridge gives attachment to the Sternothyroid and Thyro- hyoid muscles, and the portion of cartilage included between it and the posterior border gives attachment to part of the Inferior constrictor ASCENDtNa Fig. 890.—Sagittal section of a man twenty (After W. Braune.) of the thjToid and The inner surface (Fig. 892) of each ala is smooth, slightly concave, and covered by the mucous membrane of the outer wall of the sinus pyriformis above and behind; but in front, in the receding angle formed by the junction of the alse, are attached the epiglottis, the true and false vocal cords, the Thyroarj'tenoid and Thyroepiglottidean muscles, and the thyroepiglottidean ligament. The upper border (Fig. 891) is sinuously curved, being concave at its posterior part, then rising into a convex outline in front; it gives attachment throughout its whole extent to the thyrohyoid membrane. The lower border (Fig. 892) is nearly straight in front, but behind, close to the cornu, it is concave, the two parts
