It facilitates the movement of the skin, serves as a soft bed for the passage of vessels and nerves to the skin, and retains the warmth of the body, since fat is a bad conductor of heat. NLM What type of cells are found in the epidermis? In other areas, such as palms and soles, it’s thick.1 As adjectives the difference between subcutaneous and cutaneous is that subcutaneous is pertaining to the fatty layer under the skin while cutaneous is (anatomy|zoology) of, relating to, existing on, or affecting the exterior skin… Why is the hypodermis also called superficial? The skin functions as a protective barrier that interfaces with a sometimes-hostile environment. Similar determinations of the sucrose, mannitol, and inulin spaces of the stratum corneum gave mean values of 0.84, 2.21, and 1.84 mul/cm2, respectively. Flat, plate-like cells.

Sodium uptake by the outside surface of frog skin. Organization of skin microcirculation in amphibians. The subcutaneous connective tissue forms a loose layer beneath the stratum compactum and a second very thin layer next to the muscles. In the dorsal skin of the tree frog, in the connective tis sue layer, there are three layers of pigment cells xantho phores, iridophores and melanophores (Noble 1931; Frost-Mason et al. 1973 Jan;228(1):221-39. doi: 10.1113/jphysiol.1973.sp010083.

Though you cannot see it, the innermost layer is composed of subcutaneous tissue, an all-important insulator that regulates your body’s temperature and protects your insides. 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.
