skin structure and growth Flashcards
the study of skin, its nature, structure, functions, diseases and its treatment
dermatology
physician engaged in the practice of treating the skin
dermatologist
the outermost and thinnest layer of the skin
epidermis
the deepest layer of the epidermis
basal cell layer
the spiny layer above the basal cell layer, where the process of shedding skin begins
spinosum
granular layer, consists of cells that look like distinct granules
stratum granulosum
clear transparent layer just under the surface of the skin; consists of small cells through which light can pass thru
stratum lucidum
horny layer, outermost layer of the epidermis. the layer we see when we look at the skin
stratum corneum
fibrous protein that is also called the principal component of hair and nails
keratin
stratum germinativum has a special column-shaped cells produce other cells called
melanocytes
underlying or inner layer of skin
dermis/ derma corium
the outer layer of the dermis, directly beneath the epidermis
papillary layer
some papillae contain looped capillaries and others contain small epidermal structures
tactile corpuscles
deeper layer of the dermis that supplies the skin with all of its oxygen and nutrients
reticular layer
fatty layer found below the dermis
subcutaneous/adipose/subcutis tissue
— are distributed to arrector pili muscles attached to the hair follicles
motor nerve fibers
react to heat, cold, touch, pressure and pain
sensory nerve fibers
distributed to the sweat and oil glands of the skin
secretory nerve fibers
tiny grains pff pigment deposited into cells in the basal cell layer of the epidermis and papillary layers of the dermis
melanin
fibrous protein that gives the skin form and strength
collagen
excrete sweat from the skin, consist of coiled based, or secretory coil
sudoriferous (sweat) glands
tube like duct that ends at the surface of the skin to form the sweat pore
secretory coil
a hair follicle filled w keratin and sebum is formed, which may lead to acne papule or pustule
comedo
supports the overall health of skin and aids in health, function and repair of skin cells
vitamin a
important substance needed for proper repair of the skin various tissues
vitamin c
enables the body to properly absorb and use calcium; needed for proper bone development
vitamin d
helps protect the skin from the harmful effects of the sun
vitamin e
specialist in cleansing, preservation of health, beautification of skin and body
esthetician
constant over-dilation and weakening of the fragile capillary walls will cause them to become distended. they are called
telangiectasis
