What is the major factor accounting for the waterproof nature of the skin? (a) desmosomes in stratum corneum, (b) glycolipid between stratum corneum cells, (c) the thick insulating fat of the hypodermis, (d) the leathery nature of the dermis.
In elderly people, blood supply to the dermis is reduced and sweat glands are less active. This combination of factors would most affect the, : (a) ability to thermoregulate. (b) ability to heal injured skin. (c) ease with which the skin is injured. (d) physical characteristics of the skin. (e) ability to grow hair.
The reticular layer of the dermis (a) provides strength and elasticity to the skin, (b) is composed of loose connective tissue, (c) insulates to prevent heat loss, (d) forms the dermal papilla.
