Apocrine glands |
Coiled structures attached to hair follicles found in the underarms and genital areas that secretes sweat |
|
Arrector pili muscle |
Small involuntary muscles in the base of the hair follicle that causes goose flesh when the appendix contract sometimes called goosebumps and papilla |
|
Barrier function |
Protective barrier of the epidermis the cornea and intercellular matrix protect the surface from irritation and dehydration |
|
Ceramids |
Glycolipid materials that are a natural part of the skin's intercellular matrix and barrier function |
|
Collagen |
Fibrous connective tissue made from protein found in the reticular layer of the dermis gives skin its firmness topically alarge long-chain molecule protein that lies on top of the skin and binds water derived from the placentas of cows or other sources |
|
Corneocytes |
Another name for the stratum corneum sell hard and waterproof protective keratinocytes he's dead protein cells are dried out and lack nuclei |
|
Dermal papillae |
Membranes of ridges and grooves that attach to the epidermis contains nerve endings and supplies nourishment through capillaries to skin and follicles |
|
Dermis |
Also known as the derma corium cutis or true skin support layer of connective tissue collagen and elastin below the epidermis |
|
Desmosomes |
The structures that assists and holding cells together intercellular connection is made of proteins |
|
Eccrine glands |
Sweat glands found all over the body with openings on the skin surface through pores not attached to hair follicles secretion do not produce an offensive odor |
|
Elastin |
Protein fiber found in the dermis gives skin its elasticity and firmness |
|
Epidermal growth factor |
Abbreviated EGF stimulate cells to reproduce and heal |
|
Epidermis |
Outermost layer of skin off in protective layer with many cells mechanisms and nerve endings it is made up of five layers stratum corneum stratum lucidum stratum granulosum stratum spinosum and stratum germinativum |
|
Eumelanin |
I type of melanin that is dark brown to black and color people with dark colored skin mostly produced eumelanin there at these are two types of melanin the other type pheomelanin |
|
Hyaluronic acid |
Hydrating fluids found in the skin hydrophilic agent with water binding properties |
|
Leukocytes |
White blood cells that have enzymes to digest and kill bacteria and parasites these white blood cells also respond to allergies |
|
Papillary layer |
Top layer of the dermis next to the epidermis |
|
Reticular layer |
Deeper layer of the dermis that supplies the skin with oxygen and nutrients contains fat cells blood vessels sweat glands hair follicles lymph vessels arrector pili muscles oil glands and nerve endings |
|
Sebaceous glands |
Oil glands |
|
Stratum corneum |
Also known as horny layer outermost layer of the epidermis composed of corneocytes |
|
Stratum germinativum |
Also known as basal cell layer active layer of the epidermis above the papillary layer of the dermis cell mitosis takes place here that produces new epidermal skin cells and is responsible for growth |
|
Stratum granulosum |
Also known as granular layer layer of the epidermis composed of cells filled with keratin that resemble granules place cells shed from the stratum corneum |
|
Stratum lucidum |
Clear transparent layer of the epidermis under the stratum corneum thickest on the palms and hands and soles of feet |
|
Stratum spinosum |
Also known as spiny layer layer of the epidermis above the stratum germinativum layer containing decimo sons the intercellular connections made of protein |
|
Subcutaneous layer |
Also known as hypodermis subcutaneous adipose fat tissue located beneath the dermis a protective cushion and energy storage for the body |
|
Sudoriferous glands |
Sweat glands |
|
Trans epidermal water loss |
Water loss caused by evaporation on the skin surface |
|
UVA radiation |
Also known as aging rays longer wavelengths ranging between 3:20 to 400 animators that penetrate deeper on the skin then UVB causes genetic damage and cell death UVA contributes up to 95% of the sun's ultraviolet radiation |
|
UVB radiation |
Also known as burning rays UVB wavelength range between 290 to 320 nanometers UVB rays have shorter burning wavelength that are stronger and more damaging than UVA rays UVB causes burning of the skin as well as tanning skin aging and cancer |
