Skin is composed of three layers of tissue:
true
Each layer of skin is unique in structure and function and forms the basis for how
medications are administered either by injection or topically.
epidermis
The ___________ is the visible, outermost layer that makes up about 5% of the depth of
the skin. The epidermis has either four or five sublayers depending on its thickness.
stratum basale (also called the stratum germinativum); stratum spinosum, stratum
granulosum, stratum lucidum, stratum corneum.
five layers from innermost to outermost:
stratum corneum
The ______________ contains abundant amounts of the protein keratin that provides an
effective barrier that repels bacteria and other foreign matter: most substances are

stratum basale

after the older superficial cells have been damaged or lost by normal wear.
On average its takes about __ weeks to move from the stratum basale to the body
surface.
melanocytes
Specialized cells within the deepest layers of the epidermis, called ____________,
secrete the dark pigment melanin, which offers a degree of protection from the suns
ultraviolet rays. The number and type of melanocytes determine the overall pigment of
, the skin. The more melanin, the darker the skin dermis
The middle layer of the skin is the _________, which accounts for about 95% of the skins
thickness. The dermis provides a foundation for the epidermis and accessory structures
such as hair and nails. Most sensory nerves that transmit the sensations of touch,
pressure, temperature, pain, and itch are located within the dermis as are oil glands and
