Arrector Pili Muscle
The muscle that contracts and causes "goose bumps" when we are cold.
coiled structures attached to hair follicles found in the underarm and genital areas.
The protective function of the epidermis; the corneum and intercellular cement protect the surface from irritation and dehydration.
Cell division; occurs continuously in the basal cell layer
Lipid materials that are a natural part of the intercellular cement.
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 and other sources.
Membranes of ridges and grooves that attach to the epidermis.
Live layer of connective tissue below the epidermis.
The structure that assists in holding the cells together.
Sweat glands found all over the body; not attached to hair follicles, do not produce an offensive odor
Protein fiber found in the dermis; gives skin firmness and elasticity
The outermost layer of the skin; a thin, protective layer with many nerve endings.
Cells that produce amino acids and collagen.
Hair follicles and sebaceous follicles are tubelike depressions in the dermis
Oxygen atoms or molecules with unpaired electrons that cause oxidation. They steel electrons from other molecules, which damage the other molecules.
Cone -shaped elevations at the base of the follicle tat fits into the bulb. The papillae are filled with tissue that contains the blood vessels and cells necessary for hair growth and follicle nourishment.
Study of the structure and composition of tissue.
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 or a body organto stimulate functional activity or secretion; the internal messengers for the body's systems.
Hydrating fluids found in the skin; hydrophilic agent with water - binding properties.
The skin and it's extensions, such as the hair,nails, and glands
Lipid (fat) substances between coreum cells that protect the cells from water loss and irratition.
Fiber protein found in skin, hair, and nails; provides resiliency and protection to the skin.
Cells composed of keratin.
Fats or fatlike substances . Lipids help repair and protect the barrier function of the skin.
Loccated in the dermis, these supply nourishment within the skin and remove waste.
Skin - pigment; a defense mechanism to protect the skin from the sun.
Cell that produce pigment granules in the basal layer.
The top layer of the dermis next to the epidermis.
Study of the functions or activities performed by the body's structures.
A tublelike opening for sweat glans in the epidermis.
The deeper layer of the dermis, containing proteins that give the skin it's strength and elasticity.
sebaceous glands are connected to the hair follicles in the reticular layer; these produce sebum, wich protects the surface of the skin.
provides protection for the epidermis from external factors and lubricates both the skin and hair.
outer most layer of the epidermis, also called the horney layer.
First layer of the epidermis above the papiliary layer of the dermis; also known as the basal layer
layer of the epidermis composed of cells filled with keratin that resemble granules; replace cells shed from the stratum corneum.
clear layer of epidermis under the stratum corneum; found only on the palms of hands and soles of feet.
spiney layer of the epidermis abover the basal layer.
subcutaneous adipose tissue located beneath the dermis.
subcutaneous tissue located beneath the dermis.
Sudoriferous or sweat glands
excrete perspiration and detoxify the body by excreting excess salt and unwanted chemicals.
describes cappillaries that have been damaged and are now are larger, or distended blood vessels. commonly called couperose skin.
Transepidermal water loss (TEWL)
water loss caused by evaporation on the skins surface.
longer; aging rays that penetrate deeper into the skin than uvb rays.
U V B RAYS
shorter, burning rays that are stronger than uva rays.
