Shaped like a 3 sided pyramid.
Anteriomedially is the vocal process: posterior attachment for the vocal ligament.
Posteriorlaterally is the muscular process: attachment for the lateral cricoarytenoid muscle + interarytenoid muscle + aryepiglotic muscle.
Apex: corniculate cartilage + attaches the quadrangular membrane (corniculate cartilage and near apex) - superior aspect of which is the aryepiglotic fold, inferior edge of which is the vestibular fold.
The rima of the glottis, the glottis, is 60% composed of the vocal fold, and 40% composed of the vocal process of the arytenoid cartilage.
Cricoarytenoid joints, permit the arytenoids to slide towards or away from one another.
Arytenoid Cartilage + aryepiglottic fold collapses into larynx in tracheomalacia.
Cunieform and corniculate cartilages - both completely embedded in the aryepiglottic folds, provide some rigidity.
Triticious cartilage (sometimes found in thyroihyoid membrane).
