Crico-thyroideus. (F.) Dilatateur anterieur du larynx, is a small fleshy bundle, of a triangular shape, at the anterior and inferior part of the larynx. It extends from the outer space of the cricoid cartilage to the lateral parts of the inferior margin of the thyroid cartilage; and its use is to approximate, anteriorly, the corresponding margins of the cricoid and thyroid cartilages; and thus to stretch the ligaments of the glottis, which it contracts by separating the thyroid cartilage from the arytenoid.

Procollagen Proline Dioxygenase
- mixed-function oxygenase that catalyzes hydroxylation prolyl-glycyl-containing-peptide, usually in protocollagen, hydroxyprolylglycyl-peptide. The enzyme utilizes molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. EC 1.14.11.2.
