These cartilages are regarded as derivatives of posterior visceral arches of ancestors. Together they constitute the larynx, a structure characteristic of tetrapods. (...) (In mammals) Paired arytenoid cartilages help support and control the vocal cords. The cricoid cartilage is single. Two additional cartilages are present that are lacking in other vertebrates: a large ventral thyroid cartilage (...) and a cartilage in the epiglottis.[well established][VHOG] XAO:0003081 UMLS:C0023078 An anatomical cluster consisting of the epiglottus, the arytenoid cartilages, the thyroid cartilage, the cricoid cartilage and the muscles, membranes, and ligaments connecting them, and also of the mucosal covering these structures.[FEED] laryngeal CALOHA:TS-0532 EV:0100039 uberon OpenCyc:Mx4rvViOnZwpEbGdrcN5Y29ycA MA:0000414 galen:Larynx AAO:0000268 GAID:108 VHOG:0001279 A continuation of the pharynx that is involved in breathing, sound production, and protecting the trachea against food aspiration.
