In the article, Skin Deep by Nina G. Jablonski and George Chaplan, the authors are attempting to explain how the human skin color has evolved to be dark enough to prevent sunlight from destroying folate but light enough to enhance the production of Vitamin D. The changes in skin pigmentation have evolved since the age of Lucy, who is a skeleton of the ancient humans that is about 3.2 million old. Lucy is being used to determine where and why our ancestors began changing in skin pigmentation. The

Vitiligo is a skin disease in which there is a loss of pigment (color) from areas of skin, ending in abnormal patches that feel like normal skin. Vitiligo affects 0.5-1% of people worldwide. That means about two million people are affected by this disease in this country alone. Compared to how many people live on this earth , the number isn’t that large. It’s pretty rare to have this disease. One of the two million people that was affected by this disease was a music icon, the king of pop, Michael

Melanoma is a disease that develops in the cells of the skin (melanocytes). These are the cells that produce melanin, which is the pigment that gives skin its color. Melanoma can also be found in the eyes or internal organs such as the intestines. While melanoma is the most serious form of skin cancer, the source is idiopathic. Despite the cause being idiopathic, it is known that ultraviolet radiation from sources such as sunlight, and tanning beds increase the risk of melanoma development. Melanoma

had sunburn you know that it hurts right? This is because it has damaged the skin to the nerve endings and that is why we feel it. All the tissues that are between the skin and the nerves are damages causing us to feel it. Our bodies do produce melanin which does help to protect us from the UV rays of the sun but, it does not completely protect us that is why it is very important to put sunblock on at least every 90 minutes and us SPF 50 or higher. Finally let’s talk about the bacteria, fungi

spread to other parts of the body. Of course, as rarely as it occurs, melanoma is still responsible for the majority of deaths associated with skin cancer. Melanoma is a disease of the skin which occurs when cancer cells are lodged in melanocytes, the melanin (pigment) producing cells of the body which gives us our skin color. Often the melanocytes are single cells, but when collections of them form together it can result in abnormal growth patterns. If these growth patterns make the cells grow and reproduce

comprehend about albinism. They treat albinos like just an animal or a product which is invaluable in the black market. Newman (2016) found that albinism is one of the genetic diseases that caused by a mutation gene. This gene is the key to create melanin that found in the color of retinas, hair, and skin. This is why albinos have pale skin, white or blond hair and reddish eyes. Albino’s body is totally sensitivity and fragile. In an unfortunate way, many of witchdoctors in Africa strongly believe

Case Study: Vitiligo Katelynn Schnepper PHGY 220- Gerald McGraw October 4, 2014 Vitiligo is a chronic skin disorder that affects the pigmentation of the skin. Pigment is what gives the skin color and is produced by cells called melanocytes. In the disorder, the body attacks the melanocytes resulting in the loss of color in patchy areas. When the color is lost, the affected area becomes a white irregular shaped patch on the outer layer of the skin. Vitiligo can affect a very

If I ever had a chance to start any type of program it would be a place for young black males to get some guidance in life. The program would be called "Melanin Men" because the target audience for this program is black males between the ages of 8 years old all the way up to 18. I want to teach them the right way to grow up in this crazy world, so they can survive. So thats why we start at the age of eight. I also want to show these young men its not too late to turn their life around, and thats

Melanoma Melanoma is a malignant tumor that arises from pigment-producing skin cells termed melanocytes. When the cell division of these melanocytes becomes unregulated, they begin to divide and multiply too rapidly. This results in a cancerous overgrowth of these pigmented cells. Melanomas most frequently begin as a benign mole or freckle, which subsequently grow and transform into cancerous lesions. The most lethal type of skin cancer, melanoma is often a direct result of exposure to ultraviolet
