Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation.. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition.The adjective cutaneous means "of the skin" (from Latin cutis, skin). Or (in the NAV for example) the digital cushion is considered as a subcutaneous layer, and is separately included in the frog (Subcutaneous tissue of frog [Cuneal part of digital cushion] and in the torus digitalis (Pars torica pulvini digitalis; Bulbar part [Toric part] of digital cushion). In other areas, such as palms and soles, it’s thick.1 When you browse the IMAIOS website, cookies are placed on your browser. This modification is carried to an extreme in Trichobatrachus robustus, the “hairy frog,” which has dense epidermal projections on its thighs and flanks.These projections increase the surface area for gaseous exchange. 1994). Whereas the kinetics of sodium uptake and washout could be described simply, similar studies for sucrose, mannitol, and inulin were more complex and consistent with appreciable binding of the substances to the stratum corneum. not part of skin; 5 Subcutaneous Layer. 1965 Oct;11(4):538-45. doi: 10.1080/00039896.1965.10664254.

It should be noted again that the thickness of frog skin is much less than that of humans. Surprisingly, the mannitol and inulin spaces were observed to be at least twice as large as the space occupied by the tissue water, and this can be interpreted to mean that mannitol and inulin bind in appreciable amounts and thus are unsuitable markers of the sodium space. 1977 May;69(5):571-604. doi: 10.1085/jgp.69.5.571.
