Physiology Flashcards
A group of waxy lipid molecules that are an important barrier function and water holding capacity such as glycolipids
Ceramides
Lipids are reduced if…
The skin is dry damaged or mature
Organ such as the skin heart liver and kidneys have their cells replaced every..
6 to 9 months
These raise contribute up to 95% of the suns UV radiation?
Aging rays
These rays cause burning of the skin as well as tanning aging and cancer
Burning rays
Binding of protein molecules to a glucose molecule resulting in the formation of damage nonfunctioning structures this results in stiff and inflexible sagging skin
Glycation
What are the five layers of the epidermidis?
Stratum corneum,
stratum lucidum,
stratum Grandulosum,
Stratum spinosum,
Stratham Germinativum.
This “dermis” includes carrot tonight sites and mune cells and intercellular fluids
Epidermis
Hardened corneocytes (flattened squamous cells)
Corneum #1
2layer! clear cells, thick layer of dead skin cells allows light to pass through
(thickest on the palms and soles)
Spinosum
3rd layer; Production of excretion; desmosomes dissolved by enzymes.
Granulosum
4 layer. Largest layer! Langerhans immune cells. Keratinocytes, melanocytes and lipids are all produce here.
Spinosum
“E, D, S” skin layers
Epidermidis, dermis, subcutaneous
This cell can sense unrecognized foreign invaders such as bacteria and then process these antigens for removal through the lymph system.
Langerhans
eccrine glands are…
Sweat glands!
Arrector pilli muscle can cause..
Goose bumps 🦠🌡
Free radicals can be generated by outside factors including??
If , unhealthy foods, chemicals, smoke or trauma from medical treatments
The study of structure and composition is..
Skin history!
Chain of amino acids are called?
Polypeptides!!
What do peptides hold together?
Amino acids!
Each square inch of skin contains how many ft of blood vessels?
888888888888888
How many hot& cold receptors are in the body?
12
Appendages of the skin include????
💇🏻♀️💅🏽🏃🏾♀️ 🥑
Where is the thickest of skin???
Feet& hands
The gland helps regulate the internal temperature of your body!
Sudoriferous
This hormone helps stimulate cells to reproduce and heal
Epidermal growth factor
Oily substance that protects/lubricants the surface of the skin and hair
Sebum
This gland produces sebum
Sebaceous gland
The production process of injured skin to restore itself to normal thickness
Hyperproduction
Glands that excrete perspiration, regulate body temperature and detoxify the body.
Sudoriferous
What is the average pH of the acid mantle?
5.0 -6.0
Tube like depressions with oil glands attached are..
Follicles
What is TEWL???
Transepidermal Water loss
(evaporation of the skins surface)
What cells are found in the Stratum granulosum?
Strain basal, melanocytes, the spinosum.
This layer is stratum is only present in the thicker skin of the palms and soles?
Lucidum
This strain serves as effective barrier to any chemicals that might harm the living cells beneath them..
Corneum
The stratum insureds production of new skin cells. It also provides vital protection against viruses bacteria parasites or any other forms of pathogen or toxin.
Corneum
