Functions of the Skin
Appendages attached to the follicles that produce sebum.
Sebaceous glands
The support layer of connective tissues above the hypodermis
Dermis
A translucent layer made of small cells that let light pass through; thickest on the palms of the hand & sole, where our unique fingerprints & footprints are created.
Stratum Lucidum
Help regulate body temperature and eliminate minute amounts of waste products by excreting sweat.
Sudoriferous glands
Molecules formed to fight and neutralize bacteria, viruses, and antigens.
Antibodies
With the function of heat regulation; the body's average internal thermostat is set at
98.6 degrees
Reticular & Papillary
Comprises 95% of the epidermis
Keratinocytes
Connected to the hair follicles and produce oil, which protects the surface of the skin.
Sebaceous glands
A type of lymphocyte; matures in the thymus gland.
T Cells
Nerve sensors send messages to the brain and motor nerves send messages back to relay to the body how to respond in this function of the skin
Sensation
Membranes of ridges and grooves that attach to the epidermis found in the papillary layer of the dermis.
Dermal papillae
In this active layer of the epidermis, stem cells undergo continuous cell division (mitosis) to replenish the skin cells that are regularly shed from the surface.
Stratum Germinativum
Two types of sweat glands.
Apocrine & Eccrine
Three forms of UV exposure.
Double Your Points!! (describe each form)
UVA, UVB, UVC
what is synthesized and produced upon sun exposure to the sun?
Vitamin D
Large protein molecules and water-binding substances found between the fibers of the dermis.
Glycoaminoglycans (GAGS)
In this layer of the epidermis is the production of keratin granules in the cells, additional lipid production and excretion, and desmosomes dissolved by enzymes are happening.
Stratum Granulosum
According to some medical authorities, considered not to be true sweat glands because their openings connect to oil glands instead of pore openings directly on the skin's surface.
Apocrine glands
Alters protein structures and decreases biological activity.
Glycation
The hydrolipidic film, acid mantle, and melanin are all key components of this primary function of the skin.
Protection
Fluid composed of collagen, other proteins, and GAGs.
Extracellular matrix (ECM)
The largest layer of the epidermis; desmosomes are created; Langerhans immune cells, melaosomes distribution.
Stratum Spinosum
What chemical hormone does the apocrine glands produce that triggers biological reactions or communicate signals to others through scent production?
Pheromones
When do free radicals produce more free radical?
While causing oxidation reactions
