cuticleЗначение термина cuticle в knolikcuticle - cuticle cuticle - Superficial non-cellular layer covering animal or plant; secreted by epidermis. In higher plants forms a continuous layer over aerial parts broken only by stomata and lenticels; protects against mechanical injury, but chief function is preventing excessive water-loss. See also: Gutin. In Metazoa it is present in most invertebrates, mainly made of collagen-like protein, or of chitin. In Arthropoda it is firm enough to act as skeleton and is composed of chitin and protein, hardened by lime-salts in Crustacea. In insects, it has a very thin, fairly waterproof, covering of wax which prevents excessive water-loss. In vertebrates, stratum corneum, which is cellular, is occasionally called cuticle.
