Flashcards in Chapter 8 Terminology Deck (38):
The skin and its layers
The study of the skin, it's structure, functions, diseases and treatment
The primary component of the skin cells; which contains several chemical elements such as carbon, oxygen, hydrogen,nitrogen, and sulfur.
The toughest layer of the epidermis; hardened, " cornified", "horny" cells
The layer of the epidermis just below the stratum corneum; it is the palms of the hands and the soles of the feet, where there are no hair follicles
microscopic study of the skins tissue.
The layer of the epidermis below the stratum lucidum and above the the stratum spinosum; in this layer the cells become more regularly shaped and look like many tiny granules
The layer of the epidermis just above the stratum germinativum; sometimes considered part of the stratum germinativum; includes cells that have absorbed melanin to distribute pigmentation to other cells
The lowest layer of the epidermis where mitosis or cell division takes place; begins with the stratum basale, or basale cell layer, which is a single layer thick
Is the "true skin". This layer functions as the skins main support structure, since it is comprised of many connective tissues & is rich in capillaries & blood vessels.
Strong circular directional growth of hair on either side of the nape or crown
Located in the dermis. These cells respond to allergies by releasing small granules alled tistarnies
Sweat glands located throughout the entire body & are most abundant on forehead, the palms of the hands & soles of the feet.
sweat glands under the arm, in the genitals & the nipples.
Substance that binds, adds structure strength & medicates biochemical interactions between cells, such as lipids or fatty acids.
Within this layer protect the layers below the stratum corneum.
cover and protect the inside of the body
(Boil) Is a painful infection of a hair follicle & adjacent subcutaneous tissue that appears as a firm nodule w/ a center hard pus-filled core (one hair follicle).
Is plugged sebaceous gland with an opening that is not wildly dilated.
Pearly white enclosed cysts
Acute burning, itching rash, caused by excessive heat.
Is a congenital disorder that occurs when the skin lacks pigmentation (hydro-pigmentation) due to decrease in melanoma activity
Birth mark or a congenital mole, caused by dilation of a small blood vessels & usually does not disappear.
(Freckle) Small yellowish or brownish spot on the skin, particular on the face, hands, neck.
The build up of skin cells on the epidermis
A skin condition or disorder inflected by the weather or seasonal change.
A chronic inflammatory condition of the face in which the small capillaries of the face become dilated & inflamed.
Open follicle with a black surface plug, which has been oxidized & discolored due to the serums contact w/ air.
Functions of the skin
- Protection - Absorption - Sertion - Excretion - Regulation - sensation.
Layers of the skin
Layer lies directly beneath the epidermis. It is rich in blood vessels and capillaries, which provide nutrients to the upper layer.
The lowest layer of the dermis is in direct contact w/ the next layer of skin. Contain fewer blood vessels.
located below the dermis and is composed primarily of adipose (fatty) tissue.
An inflammatory disorder of the skin.
Extrinsic vs intrinsic aging
E: (skin determination) caused by external factors that are within an individuals control, such as sun exposure, smoking, & alchol.
