Stratum Corneum
outermost layer of the epidermis and is made of dead, flat skin cells that shed about every 2 weeks.
Top Layer

The Intregumentary system consists of:
Hair, Nails, AND A VARIETY OF GLANDS
HNG
Largest organ
skin
INTEGUMENT means
cover
most important function of the INTEGUMENTary system is
protection
Main Functions
A. Serving as a barrier against infection and injury.
B. Helping to regulate body temperature.

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
THERE ARE NO BLOOD VESSELS IN THE
epidermis
THE ______IS THE INNERMOST THICK LAYER OF THE SKIN COMPOSED OF LIVING CELLS.
DERMIS
The Dermis lies beneath the Epidermis and contains
Blood vessels, glands sense organs, nerve endings, smooth muscles, hair follicles.
The ______helps us to control our body temperature:
Dermis
On a cold day when the body needs to conserve heat, the Blood Vessels in the Dermis
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 ____________.
Goose Bumps
. Beneath the Dermis is the _________, (SUBCUTANEOUS LAYER)
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.
Sebaceous
The production of Sebum is controlled by ________
Hormones
_______is mildly toxic to some Bacteria - protection.
Sebum
________ONLY THE SUPERFICIAL EPIDERMIS IS BURNED, AND IS PAINFUL BUT NOT BLISTERED.
1st degree
___________DEEPER LAYERS EPIDERMIS ARE EFFECTED, COULD HAVE INFLAMMATION, BLISTERS, AND THE BURNED SKIN IS OFTEN PAINFUL.
2nd Degree
_____________THE ENTIRE EPIDERMIS IS CHARRED OR BURNED AWAY, AND THE BURN MAY EXTEND INTO THE DERMIS. OFTEN SUCH A BURN IS NOT PAINFUL AT FIRST, IF THE RECEPTORS IN THE DERMIS HAVE BEEN DESTROYED.
3rd Degree
__________POTENTIAL LIFE-THREATENING BECAUSE OF LOSS OF SKIN, WITHOUT THIS NATURAL BARRIER, LIVING TISSUE IS EXPOSED TO THE ENVIRONMENT AND IS SUSCEPTIBLE TO INFECTION AND DEHYDRATION.
EXTENSIVE THIRD-DEGREE BURN
_____protects and insulates the body.
Hair protects and insulates the body.
______GROW FROM AND AREA OF RAPIDLY DIVIDING CELLS KNOWN AS THE NAIL MATRIX or NAIL ROOT.
Nails
_______ IS LOCATED NEAR THE TIPS OF THE FINGERS AND TOES.
Nail Matrix
T/F: fingernails grow faster than toenails.
True
Hair gets its color from
melinan
