Wikipedia Meaning and Definition on 'Cuticular'
A cuticle (pronounced /ˈkjuːtɪkəl/), or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Cuticles are non-homologous, differing in their origin, structure and chemical composition.
In human anatomy, cuticle (also called eponychium) refers to several structures. It refers to the dead layers of epidermal cells or keratinocytes that produce the horn protein keratin, to the strip of dead skin cells at the base and sides of the fingernail, to the eponychium, and also to the superficial layer of overlapping cells covering the hair shaft (cuticula pili) that locks the hair into its follicle (See also Cuticle (hair)).
In zoology, the invertebrate cuticle or cuticula is a multi-layered structure outside the epidermis of many invertebrates, notably roundworms and arthropods, in which it forms an exoskeleton (see arthropod exoskeleton).[See more about Cuticular at Dictionary 3.0 Encyclopedia]
