skin regulation
An oil-water balance that protects the skins surface?
What is Hydrolipidic Film
deeper layer of the dermis that supplies the skin with oxygen and nutrients; contains fat cells, blood vessels, sudoriferous (sweat) glands, hair follicles, lymph vessels, arrector pili muscles, sebaceous (oil) glands, and nerve endings
reticular layer
the enzyme that stimulates melanocytes and thus produces melanin
What is Tyrosinase?
outermost layer of the epidermis, composed of corneocytes
what is the stratum corneum?
Tube like opening for sweat glands on the epidermis.
pores
adipose (fat) tissue located beneath the dermis; a protective cushion and energy storage for the body
subcutaneous layer
cells that produce skin pigment granules in the basal layer
what are melanocytes
layer of the epidermis composed of cells filled with keratin that resemble granules; replace cells shed from the stratum corneum
stratum granulosum
Water loss caused by evaporation on the skin's surface.
What is transepidermal water loss?
also known as the derma, corium, cutis, or true skin; support layer of connective tissue, collagen, and elastin below the epidermis.
What is the Dermis
another name for a stratum corneum cell; hardened, waterproof, protective keratinocytes; these “dead” protein cells are dried out and lack nuclei
What are corneocytes?
also known as basal cell layer; active layer of the epidermis above the papillary layer of the dermis; cell mitosis takes place here to produce new epidermal skin cells (responsible for growth)
what is the stratum germinativum?
A lipid substance between corneum cells that protect the cells from water loss and irritation.
What is the intercellular matrix
outermost layer of skin; a thin protective layer with many cells, mechanisms, and nerve endings; is made up of five layers
What is the Epidermis
guard cells of the immune system that sense unrecognized foreign invaders, such as bacteria, and then process these antigens for removal through the lymph system
What are Langerhans cells?
clear, transparent layer of the epidermis under the stratum corneum; thickest on the palms of hands and soles of feet
What is the Stratum Lucidum
sweat glands found all over the body with openings on the skin’s surface through pores; not attached to hair follicles, secretions do not produce an offensive odor
What are Eccrine glands?
top layer of the dermis next to the epidermis
What is the papillary layer
Cells that stimulate cells, collagen and amino acids that form proteins.
fibroblasts
ayer of the epidermis above the stratum germinativum layer containing desmosomes, the intercellular connections made of proteins
what is the stratum spinosum?
