|
the two layers the skin is made out of:
|
Dermis and epidermis
|
|
|
|
our thickest epidermis is our
|
palms and soles
|
|
|
|
The outer layer of dead cells are shed or washed away every ____ days
|
14-28
|
|
|
|
melanocytes produce
|
melanin
|
|
|
|
LIGHT SKINNED have about the same amout of melenocytes as ____ skinned people
|
Dark
|
|
|
|
Amount of Melanin produced in Skin depends on TWO Factors
|
Heredity and the Length of Time the Skin is Exposed to Ultra-violet radiation (tanning)
|
|
|
|
Melanin is important for protection, by absorption of Ultraviolet Radiation from the sun. All people, but especially people with Light Skin, need to minimize exposure to the sun and protect themselves from its Ultraviolet Radiation, which can Damage DNA in Skin Cells and lead to deadly forms of Skin Cancer such as
|
melenoma cancer
|
|
|
|

|
Constrict
|
|
|
|
On hot days, the Blood Vessels _____, warming the skin and increasing heat loss.
|
dilate
|
|
|
|
Tiny Muscle fibers (arrector pili muscle) attach to Hair Follicles contract and pull hair upright when you are cold or afraid, producing what is commonly called ____________.

|
hypodermis
|
|
|
|
The Dermis contains TWO major types of GLANDS:
|
Sweat glands, and Sebaceous Glands
|
|
|
|
____________(Sudoriferous Glands) PRODUCE THE WATERY SECRETIONS KNOWN AS SWEAT, WHICH CONTAINS SALT, WATER, AND OTHER COMPOUNDS.
|
Sweat Glands
|
|
|
|
_______(OIL GLANDS) PRODUCE OILY SECRETION KNOWN AS Sebum THAT SPREADS OUT ALONG THE SURFACE OF THE SKIN AND KEEPS THE KERATIN RICH EPIDERMIS FLEXIBLE AND WATERPROOF.
