Forms: 1700s– cricoarytenoid, 1800s cricoarytaenoïd, 1800s– cricoarytaenoid.

Origin: Formed within English, by compounding; modelled on a Latin lexical item. Etymons: crico- comb. form, arytenoid adj.

Etymology: < crico- comb. form + arytenoid adj., after post-classical Latin cricoarytaenoideus (1657 or earlier), cricoarytaenoides (1684 or earlier).

Anatomy.

Of or relating to the cricoid and arytenoid cartilages; esp. designating either of a pair of muscles (lateral and posterior) which originate from the cricoid and insert on to the thyroid cartilage, and serve to adduct and abduct the vocal folds.
