Melanocyte

deadly; although, if you take the right precautions and diagnose it early, it can be cured easily through surgery, radiation treatment, etc. (Is It Melanoma). Melanoma is a type of skin cancer that starts in the melanocytes, which are in the epidermis, the outermost layer of the skin. Melanocytes make the pigment melanin which protects our skin from the sun (Melanoma Skin Cancer). These cells will become cancerous when exposed to carcinogens, mainly UV rays. This is why people who have lighter…

our skin, our muscles, blood and also what helps us fight against sicknesses. Each cell plays its part, red blood cells helps supply the body with oxygen. The white blood cells help our bodies fight against sicknesses. Skin cells are called melanocytes. Melanocytes cells produce melanin, melanin is a dark brown pigment found in hair, skin and the iris of the eye on people and also animals. Melanin is responsible for tanning skin and protecting from sunlight. Animal cells and human cells are the…

The human body is split up into several systems, which each have their own set functions (Kinworthy, 5). Every system has their own limitations of what they can do. This is due to differentiation the cells within each system become specialized for specific functions (Martini, & Bartholomew, 2). If something were to happen to one of your systems, your body’s other systems could not help because their cells do not have the ability to do what the other systems cells did (Kinworthy, 5). An example…

hair, nails and skin, which is called Keratin. They are found in the Basal Layer of the Stratified Epithelium, where they multiply by dividing. Keratinocytes over time become flatter, lose their nuclei and die. The second cell type is called the Melanocytes, which produces the skin darkening pigment melanin. The cell is located in the Basal Layer of the Epidermis, the Melanosomes are relocated to the Epidermal cells. Which then makes pigmentation of the Epidermis. Melanin is responsible for…

enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes, and hair their color. Tyrosinase is a key factor in the first step of melanin production. It transforms the amino acid tyrosine to the compound dopaquinone. Then…

certain climates. Where there is more sunlight, such as in Africa, there is more need to protect the body’s reserves of folic acid. Hence, there is much more melanocytes, the cells that include melanin to protect bodies against the sun. So skin color is much lighter than those with less sunlight such as up north need less melanin and melanocytes in order to synthesize sufficient levels of vitamin D. Where environmental factors can push for natural selection over generations, they can also change…

Aging is a process that every human experiences, no matter how old that human currently is. It is the process that takes someone from a tiny infant, to a fully grown adult. As the number of years a human body sees increases, problems continually arise. As more people are able to live to older ages, it is important to study the effects aging has on the human body. Studying this event could lead to new understandings of the body and possible cures for the many issues that follow old age. It is…

Skin color is determined by five main pigments; melanin, keratin, melanoid, hemoglobin, and oxyhemoglobin. According to most researchers skin color first evolved from the Africans when they migrated to Asia and Europe. Human skin color is very diverse; it ranges all the way from dark brown to white. The Human Genome Project is one of the most known experiments to help scientists map the genome both physically and functionally. Human skin acts as a physical barrier that protects chemical and…

Malignant melanoma is a form of skin cancer that forms in melanocyte cells in the basal layer of the epidermis which produce melanin that gives human their skin, hair, and eye color. Malignant melanoma grows malignant tumors due to DNA damage to the skin cells probable to UV radiation that causes mutations and sets off skin cells to multiply rapidly and form these malignant tumors. Melanomas are closely similar to moles making it difficult for a person to distinguish from a normal mole to a…

Skin cancer is the most common cancer of all cancers, it is predicted that one of every three new cases of cancers is skin cancer. There are two types of skin cancer: melanoma and non-melanoma. Melanocytes produce melanin, which is the pigment cells responsible for skin color and also protect the body from ultraviolet rays. When these cells transform into cancerous cells, the result is melanoma. Melanoma is not as common but it is the deadliest and most dangerous type of skin cancer because it…
