Chapter 5, Problem 5RQ
Summary Introduction
To determine:
The major factors that account for the waterproof nature of the skin.
Introduction:
There are a total of six functions that are performed by the skin. The skin is comprised of several layers and the thickness of the skin also varies in distinct regions of the human body. The layers of the skin are comprised of several different kinds of cells and each cell has its own dedicated function. The skin is the primary barrier that protects the human body.

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.
The ability of the epidermis to resist rubbing and abrasion is largely due to the presence of (a) melanin, (b) carotene, (c) collagen, (d) keratin.
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.
