You asked: What type of skin cancer arises from the cells that protect from UV light?

Of all types of skin cancer, melanoma causes the most deaths because of its tendency to spread to other parts of the body, including vital organs. Most cases of skin cancer are caused by overexposure to ultraviolet (UV) rays from the sun, tanning beds, or sunlamps. UV rays can damage skin cells.

What arises from the cells that protect from UV light?

Melanocytes are derived from neural crest cells and primarily produce melanin, which is responsible for the pigment of the skin. They are found between cells of stratum basale and produce melanin. UVB light stimulates melanin secretion which is protective against UV radiation, acting as a built-in sunscreen.

Which type of cell protects the skin from UV light damage quizlet?

Keratinocytes produce melanin, the polymer responsible for protecting the skin from damaging UV light. The epidermis consists of five layers of cells, each layer with a distinct role to play in the health, well-being, and functioning of the skin.

What substance protects underlying skin cells from ultraviolet light?

Melanin gives hair and skin its color, and also helps protect the living cells of the epidermis from ultraviolet (UV) radiation damage.

Which type of skin cancer arises from the pigment producing cells in the skin?

Melanoma is a type of skin cancer that develops when melanocytes (the cells that give the skin its tan or brown color) start to grow out of control. Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can then spread to other areas of the body.

What produces the pigment that shields nuclei from UV light?

Keratinocytes phagocytize chunks of melanin produced by melanocytes and incorporate the melanin in the tops of their cells. This shields the cell’s nucleus from ultra violet light.

What layer of skin is avascular?

Epidermis. The epidermis is the outermost layer of the skin, the layer of skin which is visible. The epidermis is also the thinnest of the three skin layers. It is an avascular skin layer, so it does not contain blood vessels.

What type of cell in the skin helps protect against ultraviolet B from the sun quizlet?

Langerhans cells activate the immune system. 3. Melanin provides protection against ultraviolet (UV) radiation.

Which of following protects from ultraviolet radiation quizlet?

Keratin protects the skin from the damaging effects of ultraviolet (UV) radiation.

How does keratin protect the skin from UV?

Keratin protects skin cell DNA from the damaging effects of ultraviolet (UV) radiation. … The protein found in large amounts in the outermost layer of epidermal cells is collagen. False. The skin has a more extensive dermal layer than thin skin.

Which feature of the skin protects the body from UV damage?

The epidermis acts as a barrier that protects the body from ultraviolet (UV) radiation, harmful chemicals, and pathogens such as bacteria, viruses, and fungi. Historically, it was thought that the function of the epidermis was to regulate fluid and protect the body from mechanical injury.

Which of the following is an example of how melanin protects the skin?

Melanin protects the skin by shielding it from the sun. When the skin is exposed to the sun, melanin production increases, which is what produces a tan. It’s the body’s natural defense mechanism against sunburn.

How the skin protects us from pathogens?

The skin acts as an external barrier to bacteria, preventing infection and protecting the internal organs. The skin also protects the body from ultraviolet radiation using the pigment barrier formed from melanocyte cells found in the top of the papillary dermis and a protein layer found in the epidermis.
