The
skin has many more crucial functions than we realize in daily
life. It is therefore is not surprising that the loss of as
little as 20% of your skin can condemn you to death.Architecturally,
our skin is a constantly remodeled, intricately perfused and
inner vated three-layered structure (epidermis, dermis, subcutis).
Specialized skin "append ages" protrude from the
skin (hair, nails) or are embedded in it (sweat and sebaceous
glands). |

| Overview

The
skin is not only the largest organ of your body, but also
the heaviest: it has a surface of 1.5-2 m2 and contributes'
/7 to '/e of body weight. The skin provides a fascinating
"theater of life" in which—in contrast to
all other organs-you can directly watch, dissect, and manipulate
key principles of biology and pathology in action, and where
the environment and an individual's way of life leave unmistakable
traces for those who know how to read them.
Subjecting the skin to a professional examination, therefore,
can reveal many invaluable clues about your patient's genera!
well-being; internal disease; social, cultural, and eating
habits; psychological disturbances; and occupation. All this
provides medically very useful information, even when dermatology
is not your main field of interest.

The
skin has many more crucial functions than we realize in daily
life. It is therefore is not surprising that the loss of as
little as 20% of your skin can condemn you to death. Architecturally,
our skin is a constantly remodeled, intricately perfused and
inner vated three-layered structure (epidermis, dermis, subcutis).
Specialized skin "append ages" protrude from the
skin (hair, nails) or are embedded in it (sweat and sebaceous
glands). Two special structures-hair follicles and mammary
glands (derived from epidermis)-mark us as mammals. Figure
1.0 provides an overview of the parts of the skin that are
illustrated in the subsequent figures. Figures 1.1, 1.2 are
photomicro graphs showing normal skin from a hair-bearing
region and from the thickened palmar skin with sweat glands.
Figure 1.3 provides a three-dimensional view, showing how
the epidermis and dermis interdigitate. |
