The Best Tasting Fish In The World, Ranked 25) Rainbow Trout: This was one of the first fish I ever recall truly loving. We used to catch these in the Smokey Mountains in North Carolina when I was a kid and would cook them camping.
Both melanocyte-stimulating hormone and Î±-MSH are capable of stimulating melanin production in sun exposed areas under the action of ultraviolet light. Prolonged dosages of Î±-MSH, however, will not only increase pigmentation of the skin, but may also cause hypertrichosis (excessive hair growth) and skin atrophy.
So, now that we know all about the skin we can start to actually understand tans and sunburns. When you get a tan, what is actually happening is that the melanocytes are producing melanin pigment in reaction to ultraviolet light in sunlight. Ultraviolet light stimulates melanin production. The pigment has the effect of absorbing the UV radiation in sunlight, so it protects the cells from UV damage.
