Physiology
The dilation of the capillary walls
couperose skin or telangiectasia
White blood cells that have enzymes to digest and kill bacteria and parasites. Also responds to allergies
Leukocytes
Consists of layers of a connective collagen tissue with many small pockets and holes
DEJ Dermal/Epidermal Junction
Gives contour and smoothness to the body. Is also a source of energy
Subcutaneous Tissue
Epidermal cells composed of keratin, lipids, and other proteins
What is keratinocytes
What removes and depletes lipids?
a. free radical damage
b. HEV light exposure
c. peptides
d. exfoliation
a. free radical damage
b. HEV light exposure
c. peptides
d. exfoliation
Type of lymphocytes that attacks virus-infected cells, foreign cells and cancer cells
T cells
95% of the epidermis. These cells contain both proteins and lipids
Keratinocytes
Denser deeper layer of the dermis, is comprised mainly of collegen and elastin
What is the Reticular Layer
also known as the basal layer; active layer of the epidermis above the papillary layer of the dermis; cell mitosis takes place here to produce new epidermal skin cells
What is germinativum
The barrier function of the skin includes?
a. hair
b. follicles
c. pores
d. acid mantle
a. hair
b. follicles
c. pores
d. acid mantle
What are two types of sweat glands and where are they found
Apocrine glands found under the arms and the genital area
Eccrine glands found all over the body but primarily the foreheads, palms of the hands and soles of the feet
Tube like opening for sweat glands on the epidermis
What are pores
What layer connects the dermis to the epidermis. Collegen and elastin are loose and more widely placed here,
Papillary Layer
stratum lucidum
What are the clear cells, present only where the skin is thick, on the soles of the feet and the palms of the hands
chronic vascular disorder characterized by varying degrees of skin redness and congestion
Rosacea
Ingredients that stimulate cell turnover
Vitamin A, aha, alpha lipoic acid other growth factors
Tube like depressions with oil glands attached to them
Follicles
A protein substance of complex fibers that gives the skin its strength and is necessary for wound healing
Collegen
Which are cells that produce pigment granules in the basal layer
Melanocytes
As estrogen depletes, skin begins to
a. darken significantly
b. reproduce more rapidly
c. lose its tone
d. become more elastic
a. darken significantly
b. reproduce more rapidly
c. lose its tone
d. become more elastic
A group of waxy lipid molecules that are important to barrier function and water-holding capacity. Fifty percent of lipids in stratum corneum are..
Ceramides
Lipid substances between corneum cells that protect the cells from water loss and irritation
What is Intercellular matrix
They help collegen and elastin retain moisture
Glycosaminoglycans
What layer is above the stratum germinativum; where cells continually devide and change shape
Stratum Spinosum "Spiny Layer"
