The epi/derm/is forms the protective covering of
the body and does not have a blood or nerve supply.
the epidermis is dependent on the
dermis’ network of capillaries for nourishment.
As oxygen and nutrients flow out of the capillaries in the dermis, they pass through
tissue fluid, supplying nourishment to the deeper layers of the epidermis.
When you talk about the outer layer of skin, you are referring to the / / .

When you talk about the deeper layer of skin, consisting of nerve and blood vessels, you are talking about the / .

palms of the hands and the soles of the feet, but relatively thin over most other areas.

The combining form (CF) derm/o refers to
the skin.
Derm/o/pathy is a disease of the
skin
Although the epidermis is composed of several layers, which layers are of the greatest importance?
the (3) stratum corneum and the (4) basal layer are of greatest importance.
The stratum corneum is composed of
dead, flat cells. Its thickness is correlated with normal wear of the area it covers.
Only the basal layer is composed of
living cells. It is where new cells are continuously reproduced. Label these two structures in Figure 3-2.
3–6 As new cells form in the
basal layer, they move toward the stratum corneum. Eventually, they die and become filled with a hard protein material called keratin.
The relatively waterproof characteristic of keratin prevents
body fluids from evaporating and moisture from entering the body. These keratinized cells gradually flake away and are replaced in a continuous cycle.
The entire process by which a cell forms in the basal layers, rises to the surface, becomes keratinized, and sloughs off takes about
1 month.
In addition to derm/o, two other CFs for the skin
are cutane/o and dermat/o.
Cutane/ous means pertaining to the .

As discussed previously, suffixes -al, -ic, -ior, and -ous are
adjective endings that mean pertaining to.
Terms such as derm/al and derm/ic mean

3–14 In the basal layer, specialized cells, called melan/o/cytes, produce
a black pigment called melanin.
Production of melanin increases with
exposure to strong UV light. This exposure creates a suntan that provides a protective barrier from damaging effects of the sun.
The CF melan/o refers to
the color black.
Build a word that literally means black cell
melan/o/cyte
black tumor: / .
melan/oma
Activity of melan/o/cytes is genetically
regulated and inherited. Local accumulations of melanin are seen in pigmented moles and freckles. Environmental and physiological factors also play a role in skin color.
Absence of pigment in the skin, eyes, and hair is most likely caused by
an inherited inability to produce melanin.
This lack of melanin results in the condition called
albin/ism. A person with this condition is called an albino.
Deficiency or absence of pigment in the skin, hair, and eyes caused by an abnormality in production of melanin is known as / .
albin/ism
The number of melan/o/cytes is about the
same in all races.
Differences in skin color are attributed to
production of melanin. In people with dark skin, melan/o/cytes continuously produce large amounts of melanin. In people with light skin, melan/o/cytes produce less .
In people with light skin, melan/o/cytes produce less .
