What color is eumelanin?
Dark brown to black
Support layer of connective tissues below the epidermis.
Dermis
Sweat glands found all over the body with openings on the skins surface through pores.
Eccrine glands
Fibrous protein that forms elastic tissue and gives skin its elasticity.
Elastin
Outermost layer of skin.
Epidermis
What stimulates melanin production?
Exposure to sunlight
Collagen and elastin are more widely spaced in the reticular layer than the papillary layer. T/F
False
Elastin and collagen are very easily replaced by the body. T/F
False
Triglycerides, ceramides, waxes, and fatty acids are made in the stratum Germinativum. T/F
False (Granulosum)
The liver is the largest organ of the body. T/F
False (skin)
The hypodermis increases and thickens with age. T/F
False (thins)
These take electrons from compounds in the body such as proteins, lipids, or DNA.
Free radicals
Binding of a protein molecule to a glucose molecule, resulting in the formation of damaged, nonfunctioning structures.
Glycation
White Boole cells that have enzymes to digest and kill bacteria and parasites.
Leukocytes
This connects the dermis to the epidermis.
Papillary layer
Where do phytoestrogens come from?
Plants
What are the basic material and building blocks for body tissue?
Proteins
Denser and deeper layer of the dermis, comprised mainly of collagen and elastin.
Reticular layer
Chronic vascular disorder characterized by couperose veins and congestion of the skin.
Rosacea
What type of glands secrete oil?
Sebaceous
What term refers to the study of the structure and composition of the skin?
Skin Histology
What is a characteristic of healthy skin?
Slightly acidic
Single layer of basal cells laying on a "basement membrane".
Stratum Germinativum
What is the bottom layer of the epidermis?
Stratum Germinativum
This is composed of cells that resemble granules and are filled with keratin.
Stratum Granulosum
Which layer of the epidermis is known as the grainy cells?
Stratum Granulosum
Top, outermost layer of the epidermis.
Stratum corneum
Thin, clear layer of dead skin cells under the stratum corneum.
Stratum lucidum
This is also known as the spiny layer.
Stratum spinosum
Loose connective tissue and adipose tissue found below the reticular layer.
Subcutaneous layer
What is NOT a function of lymph?
Supplying nutrients to the skin
Dilation of the capillary walls.
Telangiectasia
Comedones are formed when the ducts of sebaceous glands become clogged. T/F
True
It is important for an Esthetician to consider how the skin cell layers function before choosing ingredients and treatments for clients. T/F
True
Oxidation caused by free radicals continues in a chain reaction that can oxidize millions of other compounds. T/F
True
Sudoriferous glands help to regulate body temperature by excreting swear. T/F
True
UVA rays are more prevalent than UVB. T/F
True
What type of ultraviolet radiation is known as the burning rays?
UVB
What percentage of hair is comprised of hard keratin?
90
This creates a protective cushion that gives contour and smoothness to the body, as well as providing a source of energy for the body.
Adipose tissue
What is NOT a method by which the body maintains thermoregulation?
Adsorption
Coiled structures attached to the hair follicles found under the arms and in the genital area.
Apocrine glands
