Integumentary System (skin)

People with lighter skin have less pigmentation. Usually this occurs from Vitamin D deficiency of a descent group. We obtain vitamin D through sun exposure, so granted when we do not have access to sunlight we become deficient in it. Apply this to a population of people over time, and skin tone adapts within that population. People who "burn easily" have adapted to survive without access to the sun--therefore, when they spend to much time outside they "burn up." And here is where the clever sunscreen propagators come in...

it might because when u get tan it is only a few layers deep in your skin so when u kill the top layer it will make your tan lighter and if u keep doing it u will lose all your tan

The top layers of our skin are dead already. Only the very bottom layer of the epidermis is alive, but it is covered by many layers of dead skin. If you are on an acne medication, chances are your skin is in fact thinned out a bit, making it more sensitive to sun exposure. What medication are you referring to?

Skin traction is the smoothing of skin's wrinkles by "spreading the skin." For instance, imagine you'd like to write a phone number on the back of someone's hand. You might put your thumb and forefinger on the skin, and then spread the two apart to "tighten" the skin. That is skin traction.

the pigment in your skin

Epidermis.

Certain metals can be blackened or streak by perspiration...

Human skin is an example of an organ because it provides protection for the rest of our body.

Yes, i believe they are. That is why they need only to swab the inside of a mans mouth to see if he is the father of a child.

lentigines are dark patches on the skin mostly found on the elderly, they are also moles and freckles

More nerve endings and hardened skin due to constant use ie calluses?

Stratified Squamous Epithelium

from the Latin ; integumentum, which means 'a covering'.

So .. skin, hair, nails, scales or feathers, sweat glands.

Everything that acts to physically protect the parts inside.

The Stratum Lucidum

Skin reactions to jewelry are most commonly caused by a nickel allergy.

rough skin

It all depends on the type of handcream. Look on the back of the label to find out.

Dust is made of just about everything. Household dust is composed primarily of things like human skin and hair, waxes, pollen, mold, fungi, lichen, tiny particles of wood, paint, fibers from fabrics such as wool, nylon, rayon, acrylic (and in the disco '70s lots and lots of polyester), foam rubber, sheet rock, plant and vegetable matter, insect parts, and of course every form of pollution such as auto and industrial emissions, heavy hydrocarbon waste from your oil or gas heater, even tiny bits of metal debris from door hinges or any place where metal and friction meet, lots of food waste, and loads of paper fiber... If you take a few fingers full out of your vacuum cleaner, put it in a plastic bag, and bring it to school, you can look at a glob under a microscope at various powers and see all kinds of really nasty looking things in there. You'll need to pull the blobs apart to differentiate some of the more twisted items - but it's totally hideous. If you're wandering about it, it's nothing new. We evolved with dust, all life did. Dust is more ancient than life itself. A point or two of interest. Lead paint makes inhalable lead dust. Asbestos products make asbestos dust. Smoke of any sort creates dust. Lead levels in humans as a result of exposure to inhalable lead dust from paint is not only measurable (from a study done in Philadelphia) but dangerously high in some cases. People with mold or fungi allergies react most in fall and spring when mold and fungi levels are high, from inhaling the dust they create. A disease recently dubbed Multiple Chemical Sensitivity is a condition where certain people suddenly and inexplicably become allergic to just about every synthetic chemical produced by man, and have intense breathing problems as a result of the chemical dust which envelops us every day from common plastics which are found on every table, counter, desk, wall, computer, fabric, shoe, soaps, shampoos, even in ice cream...everything; and the dust from dyes which coat every thing around us, the walls, the furniture, clothing, hair, carpets, cars, roads, make-up; and pulp dust from the ultimate culprit of all, paper, which not only contains synthetics, plastics as fillers, but bonded together with urea formaldehyde which is toxic, mutagenic, hyper-allergenic, carcinogenic, and smells real nasty. Urea formaldehyde, as a binder, is emitted from paper as a vapor, and because it is a binding agent binds tiny particles and vapors together to make more dust, which in turn concentrates the urea formaldehyde into a potent pellet for inhalation. People with MCS have it rough for years until a reluctant diagnosis is made - very few doctors will, if any, hand out a diagnosis of MCS, which isn't officially recognized as a disease, but only debated as a syndrome. Comets are made primarily of dust. In space, dust is more primitive, mostly frozen bits of gaseous ice crystals, a very small percentage of metals and ores, debris from planets and large objects which have been impacted by meteorites and comets.

It is a histamine release. Most people have histamines that help fight off infections. Some people release more histamine than necessary and it can cause itching and rashes. Whilst there is that rare case that 1 in out of every 1000 people have what they call an Atypical Antibody in their red blood cells. Antibodies contain histamines and when you have an atypical antibody, instead of your histamines releasing normally they tend to just dump out histamines into the body wasting them. Meaning you are releasing too many histamines. I would advise you go to a doctor and have a blood test done to determine whether or not you have this antibody. It's nothing serious and there's nothing you can really do about it. But it will help you understand a lot of what is going on with your body. People with this antibody tend to have really severe allergies.

Several GREEN copper salts that can be created from combinations of copper and other chemicals such as copper sulfate, copper acetate etc. The Statue of Liberty is green as aiys copper covering is exposed to the salt water and heat. Your skin has many chemicals in sweat that attack the copper bands and allow them to corrode and oxudize turning the resulting chemicals green on your hand. You can also notice this action on copper wires that are exposed to the outside elements.

The only time I've ever heard of this happening was when someone ate LOTS of carrots - I think it was some screwy diet. the beta carotene in the carrots turned their skin orangish. I would imagine you'd have to eat an awful lot of carrots for that to occur.

There may be other foods that will do this - especially ones with beta carotene - but I've never heard of any. Are you mad?!! Of course not. Although the exeption is carrots, exept your skin goes more yellow, because of too much of a certain vitamin When my son was a baby one of the only foods he would eat were sweet potatoes and he ate a lot of them. His skin did turn yellow due to the Vitamin A content in the food. So, while this may not be uncommon in babies, I think it would be unusual for an adult simply because our diets are so much more varied.

Any food that contains large amounts of beta carotene can turn skin orange. It is first noticed on the palms of the hands and soles of the feet. It may even make it to the tip of your nose. Carrots, sweet potatoes, mango, and cantelope all contain large amounts of beta carotene. Even some green vegetables (spinach, kale) have a large amount though the color is green because of large amounts of chlorophyll. It is unusual, but nonetheless possible and happens. It is benign and will eventually fade.

An oily secretion from glands. Example: he has higher sebum production.

No. the dermis is where the blood vessels and connective tissue are located.

The sebaceous glands, also known as oil glands, prevent water loss. These glands are found in the dermis, and secrete sebum to protect the outer layer of the skin.
