Cricoid Cartilage

 

the unpaired cartilage of the larynx in terrestrial vertebrates and in man, a derivative of the fifth visceral arch. In mammals the broad part of the cricoid cartilage —the quadrate lamina—faces posteriorly; the narrow part—the arch—faces anteriorly. The cricoid cartilage is movably attached to the thyroid and arytenoid cartilages of the larynx above and to the first cartilage of the trachea below.
