Corniculate and cuneiform cartilages

Small paired cartilages: the corniculates on the apices of the arytenoids, the cuneiforms in the aryepiglottic folds, which they strengthen.

Key points

• Corniculate on the arytenoid apex.
• Cuneiform in the aryepiglottic fold.
• Both help support the laryngeal inlet.
• Laryngeal cartilages: 4th and 6th arches.
• Corniculate: elastic cartilage.
• Elastic cartilage: elastic fibres, does not calcify.
