What type of cell is responsible for the color and tone of our skin?
There are cells within the bottom layer of the epidermis (the stratum basale or stratum germinativum) called melanocytes. Melanocytes secrete a pigment called melanin which is responsible for giving our skin its color. Their main function though is to shield the nuclei of the keratinocytes (the main cells of the epidermis) to protect them from ultraviolet radiation from the sun. That's why we appear to tan in the sun.
What is the strongest factor in increasing pigmentation in the skin is the stimulating effect of what on melanocytes?
Sun
How do melanocytes protect skin cells from UV damage?
Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.
What is the functional relationship between melanin melanocytes and tanning of the skin?
Melanocytes make the pigment melanin in response to sunlight. The pigment is protective. The pigment in the skin appears as "a tan". More sun = more tan. Sunlight can cause cancer of the skin. A person with a darker skin is more protected. People who live in areas with a lot of sun have adapted to that sun by having darker skin. Of course, when they move to other areas, they pass on the gene for darker skin even if it isn't necessary.
Is there melanin in melanocytes?
Melanocytes produce melanin.
How do you increase melanocytes?
How do you increase melanocytes?
Does solar store energy from the sun?
The sun activates solar cells. The electricity created is stored in batteries.
What do melanocytes do?
Melanocytes produce melanin which contributes to pigmentation of the skin.
What causes freckles on your face like how are freckles created on your skin?
Freckles are caused by too much exposure to UV-B radiation. The exposure to UV-B radiation activates melanocytes, and this increases melanin production, which in turn causes freckles to become more darker and more noticeable.
What happens to melanocytes in the condition of albinism?
differentiate melanin melanocytes and albinism
Why does sun exposure increase the risk for malignant melanoma?
The melanocytes are part of the integument's photoprotective mechanism; in response to sunlight, they produce melanin that has a protective role from the sun's ultraviolet rays.
Why you become tanned after sitting in the sun?
When the skin is exposed to sunlight, which stimulates the melanocytes to produce more of the melanin pigment, tanning occurs.
