Rosacea
-Capillaries chronically dilated
-skin inflam., papules, pustules
-more women than men
-medical condition
-30-60 yr olds
-tzone
-cause unclear/digestive disorder
Telangeictasis
-caused by dilated capillaries
-appear as fine spidery veins, visible on skins surface
-usually on nose and cheeks
due to aging and sun exposure
-genetic weakness and nutrition defieciency
-the wall of vessels loses elasticity
Hyperemia
-Chronic state of capillary dilation
-mild or severe reddening of the skin
-may develop telaniectasis later in life
-resulting from increased amounts of blood in the capillary vessels leading to weakening the capillary walls
Homeostasis
The process of keeping the internal environment of the body stable by making adjustments to changes in the external environment.
Function of the nervous system
to recieve stimuli and transmit messages within the body so adjustments can be made that are necessary for survival.
Nucleus
dense and active protoplasm found in the center of the cell. (where reproduction and metabolism happens)
Cytoplasm
All the protoplasm of a cell except in the nucleus, where watery fluid that contains food material for growth, reproduction and self repair of the cell are.
Cell Membrane
Encloses the protoplasm and lets soluble substances to enter and leave the cell.
Epithelial
covers surfaces, lines cavaties and forms tubes
Connective
forms protective, supporting and binding structures (collagen and fat)
Muscle
has contractile ability to produce movement
Nerve
includes the sensory, coordinating, and conducting structures (transmitting messages)
Liquid
serves as a carrier of food, waste products and horomones by means of lymph and blood
masseter
for opening and closing the mouth (chewing)
bussincator
muscle of the cheek between the upper and lower jaw that compress the cheeks and air between lips
sterno-cliedo mastoid
muscle of the next that lowers and rotates the head
frontalis
front poraises the eyebrows and draws scalp forward casing wrinkles across forehead
orbicularis oris
band around moth that compresses, contracts and puckers the lips
zygomaticus
major and minor muscles extending from the zygomatic bone to the angle of the mouth that elevates the lip (laughing)
corrugator
muscle beneath the frontalis and orbicularis oculi, that draws eyebrow down and wrinkles the foredead vertically
afferent
(sensory) transmits nerve impulses toward the CNS
efferant
(motor) transmit nerve impulses away from the CNS
5th crainal nerve
cheief snsory motor of mastification
7th cranial nerve
chief motor, controls facial expressions
Epidermis
-covers
-6 layers
-straified epithilim
-mostly dead skni cells
-consists of the horny later which estheticians mostly work on
-A vascular
-constant state of renewal
-where keratinization happens
-arteries and veins
Dermis
-connects
-vascular
-"true skin"
-papillary is 1/5
-reticular layer is 4/5
-blood, lymph, sud. and seb. glands, collagen and elastin
Hypodermis
-cushion
-pressure receptors
-adipose tissue
Keratinization
-changes every 4-6 weeks and 28 days
-starts in germinitive layer and ends in horny
-cells are born, dehydrate, die and then turn into keratin before sloughing off
-new cells are always plushing up
-never ending process
-controlled by the endocrine system
-affected by age and climate
how to the pilo sebaceous follicles function?
combines with perspiraction tyo create hydro lipid film to protect skin and prevent moisture loss
-1 to 2 grams in 24hr period
Aprocine (suderiferous gland)
-alkaline in nature
-found mainly in groin and axilla
-responisble for odor
-opens next to pilo sebaceous unit
Eccrine (suderiferous gland)
-acidic in nature
-found everywhere on body
-opens on skins surface
Define pH
Potential Hydrogen
-acidicty or alkalinity of a substance
Acid Mantle
-Skin produces sebum and sweat that creates a barrier on the surface against certain forms of bacteria
-pH is 4.5-6.2
Buffer Capacity
ability to return to the normal value of approximately pH 5 after such changes
Three types of fatty compnents in the skin
1. sebum
2. hydro-phobic: keratinization
3. hydro-phillic: persp. and sebum on hydro lipid film
Inibition of the horny layer
swelling of the horny layer cells from certain cosmetic products containing mostly fluids when h20 and hydrophilious lipids are combined (rose flower)
Horny assimilation
Products containing lipids and protein constituently surround and penetrate the cells of the superficial strata
