Descripción

The Cricoid Cartilage (cartilago cricoidea) is smaller, but thicker and stronger than the thyroid, and forms the lower and posterior parts of the wall of the larynx. It consists of two parts: a posterior quadrate lamina, and a narrow anterior arch, one-fourth or one-fifth of the depth of the lamina.

The arch (arcus cartilaginis cricoideæ; anterior portion) is narrow and convex, and measures vertically from 5 to 7 mm.; it affords attachment externally in front and at the sides to the Cricothyreiodei, and behind, to part of the Constrictor pharyngis inferior.
