Subcutaneous tissue located beneath the dermis.
Membranes of ridges and grooves that attach to the epidermis.
Lipid materials that are a natural part of the intercelluar cement.
First layer of the epidermis above the papillary layer of the dermis; also known as the basal layer.
Hair follicles and sebaceous follicles are tube like depressions in the epidermis.
Cells that produce amino acids and collagen.
They are connected to the hair follicles in the reticular layer; these produce sebum, which produce sebum. which protects the surface of the skin.
Clear layer of Epidermis under the stratum corneum; found only on the palms of hands and soles of feet.
The protective barrier of the epidermis; the corneum and intercelluar cement protect the surface from irritation and dehydration.
Cells that produce pigment granules in the basal layer.
Fats or fatlike substances. Lipids help repair and protect the barrier function of the skin.
Cone-shaped elevations at the base of the follicles that fit into the bulb. The papillae are filled with tissue that contains the blood vessels and cells necessary for hair growth and follicle nourishment.
Layer of the epidermis composed of cells filled with keratin that resemble granules; replace cells shed from the stratum corneum.
Transepidermal Water Loss
(TEWL) Water loss caused by evaporation on the skin's surface.
Located in the dermis, these supply nourishment within the skin and remove waste.
Cells composed of keratin.
Fiber protein found in skin, hair, and nails; provides resiliency and protection to the skin.
Lipid substances between coreum cells that protect the cells from water loss and irritation.
Fibrous, connective tissue made from protein; found in the reticular layer of the dermis; gives skin its firmness. Topically, a large, long-chain molecular protein that lies on the top of the skin and binds water; derived from the placentas of cows or other sources.
Shorter, burning rays that are stronger than UVA rays.
Longer, aging rays that penetrate deeper into the skin than UVB rays.
Sudoriferous or Sweat Glands
Excrete perspiration and detoxify the body by excreting excess salt and unwanted chemicals.
Describes capillaries that have been damaged and are now larger; or distended blood vessels. Commonly called couperose skin.
Protein fiber found in the dermis; gives skin its elasticity and firmness.
Sweat glands found all over the body; not attached to hair follicles, do not produce an offensive odor.
The structures that assist in holding the cells together.
Spiny layer of epidermis above the basal layer.
Protective lipids and secretions on top of the skin.
The skin and its extensions, such as the hair, nails, and glands.
Secretions produced by one of the endocrine glands and carried by the bloodstream or body fluid to another part of the body or a body organ to stimulate functional activity or secretion; the internal messengers for most of the body's systems.
Cell division; occurs continuously in the basal cell layer.
Outermost layer of the epidermis, also called the horny layer.
Live layer of connective tissue below the epidermis.
Arrector pili muscle
The muscle that contracts and causes " goose bumps" when we are cold.
The outermost layer of skin; a thin, protective layer with many nerve endings.
Oxygen atoms of molecules with paired electrons that cause oxidation. They steal electrons from other molecules, which damages the other molecules.
Study of the structure and composition of tissue.
Hydrating fluids found in the skin; hydrophilic agent with water-binding properties.
Study of the functions or activities performed by the body's structures.
A tube like opening for sweat glands on the epidermis.
Skin pigment; a defense mechanism to protect skin from the sun.
Coiled structures attached to hair follicles found in the underarm and genital areas.
Adipose (fat) tissue
A protective cushion that gives contour and smoothness to the body.
Subcutaneous adipose tissue is located beneath the dermis.
The top layer of the dermis next to the epidermis.
The deeper layer of the dermis, containing proteins that give the skin its strength and elasticity.
Provides protection for the epidermis from external factors and lubricates both the skin and hair.
The technical name for the nail.
Motor nerve fibers
Sensory nerve fibers
Send messages to the brain to react to heat, cold, pain, pressure, and touch.
Secretory nerve fibers
They regulate excretion from sweat glands and control sebum output to the surface of the skin.
An esthetician's primary focus
is on preserving, protecting, and nourishing the skin.
