The inferior half of the posterior surface of the epiglottis is raised slightly to form an epiglottic tubercle.
The two arytenoid cartilages are pyramid-shaped cartilages with three surfaces, a base of arytenoid cartilage and an apex of arytenoid cartilage (Fig. 8.213):
The base is concave and articulates with the sloping articular facet on the superolateral surface of the lamina of cricoid cartilage.
