Adoption of azygos, hemiazygos, and dartos.

Exceptions to the anatomical nomenclature rule that names must be in proper Latin include a few terms that contain borrowed Greek adjectives that are not declined like Latin words. Adoption of these adjectives into Latin would change about a half-dozen terms, e.g., vena azyga, vena hemiazyga, and fascia darta. The anatomical nomenclature rules apply only to the Latin terms, so there is no requirement to alter the way azygos, hemiazygos, and dartos are used in equivalent terms in other languages. Clin.
