Arytenoid cartilage - wikipedia Arytenoid cartilage Arytenoid cartilage The cartilages of the larynx seen from behind Details Precursor 4th and 6th pharyngeal arch Identifiers Latin Cartilagines arytaenoideae MeSH A02. 165.507. 083 Dorlands / Elsevier c_12 / 12217087 TA A06. 2.04. 001 FMA 55109 Anatomical terminology ( edit on Wikidata ) The arytenoid ( / ær ɪˈtiːnɔɪd / ) cartilages are a pair of small three - sided pyramids which form part of the larynx, to which the vocal folds ( vocal cords ) are attached. These allow and aid in the vocal cords ' movement. Each is pyramidal or ladle - shaped in form ( arytenoid comes from Greek arytaina meaning ladle + eidos, meaning form ), and has three surfaces, a base, and an apex. Contents 1 Structure 1.1 Surfaces 1.2 Base and apex 2 Function 3 Additional images 4 References Structure Surfaces The posterior surface is a triangular, smooth, concave, and gives attachment to the arytenoid muscle and transversus. The antero - lateral surface is somewhat convex and rough. On it, near the apex of the cartilage, is a rounded elevation ( colliculus ) from which a ridge ( crista arcuata ) curves at first backward and then downward and forward to the vocal process. The lower part of this crest intervenes between two depressions or foveæ, an upper, triangular, and a lower oblong in shape ; the latter gives attachment to the vocalis muscle. The medial surface is narrow, smooth, and flattened, covered by mucous membrane, and forms the lateral boundary of the intercartilaginous part of the rima glottidis. Base and apex The base of each cartilage is broad, and on it is a concave smooth surface, for articulation with the cricoid cartilage. Its lateral angle is called the muscular process Its anterior angle is called the vocal process The apex of each cartilage is pointed, curved backward and medialward, and surmounted by a small conical, cartilaginous nodule, the corniculate cartilage. Function They allow the vocal folds to be tensed, relaxed, or approximated. The arytenoids articulate with the supero - lateral parts of the cricoid cartilage lamina, forming the cricoarytenoid joints at which they can come together, move apart, tilt anteriorly or posteriorly, and rotate.
