Chapter 7 Flashcards
Acne
Acne vulgaris; skin disorder characterized by chronic inflammation of the sebaceous glands from retained secretions and propionibacterium acne bacteria
Arrector pili muscles
Goose bumps; Small, involuntary muscles in the base of the hair follicle that cause goose flesh
Callus
Thickening of the skin caused by continued, repeated pressure on any part of the skin, especially the hands and feet
Collagen
Fibrous protein that gives the skin form and strength
Comedo (plural: comedones)
Blackheads; hair follicle filled with keratin and sebum
Dermal Papillae (singular: dermal papilla)
Small, cone-shaped elevations at the base of the hair follicles that fit into the hair bulb
Dermatologist
Physician who specializes in diseases and disorders of the skin, hair, and nail
Dermatology
Medical branch of science that deals with the study of skin and its nature, structure, function, disease, and treatment
Dermis
Derma, corium, cutis, or true skin; underlying or inner layer of the skin
Elastin
Protein base similar to collagen that forms elastic tissue
Epidermal-dermal junction
The top of the papillary layer where its joins the epidermis
Epidermis
Outermost and thinnest layer of the skin; made up of five layers
Esthetician
A specialist in the cleansing, beautification, and preservation of the health of skin on the entire body, including the face and neck
Eumelanin
A type of melanin that is dark brown to black in color
Keratin
Fibrous protein of cells that is also the principle component of hair and nails
Melanin
Tony grain of pigment (color matter) that are produced by melanocytes and deposited into cell in the stratum germinativum layer and in the papillary layer. Two types of it
Melanocytes
Cells that produce the dark pigment called melanin
Motor nerve fibers
Fibers of the motor nerves that are distributed to the arrector pili muscles attached to hair follicles. Motor nerves carry impulses from brain to muscles
Papillary layer
Outer layer of the dermis, directly beneath the epidermis
Papule
Pimple, small elevation on the skin that contains no fluid but may develop pus
Pheomelanin
A type of melanin that is red to yellow in color; mostly in people with light skin
Propionibacterium acnes
P. Acnes; technical term for acne bacteria
Pustule
Raised, inflamed papule with a white or yellow center containing pus in the top of the lesion referred to as the head of the pimple
Reticular layer

Sebaceous glands
Oil glands; glands connected to the hair follicle. Sebum is the fatty or oily secretion of the sebaceous glands
Sebum
A fatty or oily secretion that lubricates the skin and preserves the softness of the hair
Secretory coil
Coiled base of the sudoriferous (sweet) gland
Secretory nerve fibers
Fiber that are distributed to the sudoriferous glands and sebaceous glands.
Sensory nerve fibers
Fibers that react to heat, cold, touch, pressure, and pain. Sensory receptors that send messages to the brain
Stratum corneum
Horny layer; outer layer of the epidermis
Stratum germinativum
Granular layer; layer of the epidermis composed of cells that look like granules and are filled with keratin; replaces cells shed from the stratum corneum
Stratum lucidum
Clear, transparent layer of the epidermis
Stratum spinosum
The spiny layer
Subcutaneous tissue
Adipose or subcutis tissue; fatty tissue that gives smoothness and contour to the body , contains fat for energy , and also acts as a protective cushion for the outer skin
Sudoriferous glands
Sweat glands; excrete perspiration and detoxify the body by excreting excess salt and unwanted chemicals
Tactile corpuscles
Small epidermis structures with nerve endings that are sensitive to touch and pressure
Vitamin A
Supports the overall health of the skin; aids in the health , function, and repair of skin cells, has been shown to improve the skins elasticity and thickness
Vitamins C
Repair of the skins and tissues; promotes the production of collagen in the skins dermal tissue; aids in and promotes the skins healing process
Vitamin D
Helps body to properly absorb and use calcium, the element needed for proper bone development and maintenance; promotes rapid of the skin
Vitamin E
Helps protect the skin from the harmful effects of the sun’s UV light
