MiLady Chapter 10 Review

Waxy lipid molecules important to barrier function and water holding capacity.

Ceramides

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
