Relevance. In order to keep cool in the context of greater exposure to sun, this meant being able to sweat more profusely and effectively. Melanin is essentially what allows the human body (the skin) to darken when sunlight (or, ultraviolet rays) hits it. When melanin is produced in melanocytes, this pigment is packaged into granules, not unlike the way the green pigment chlorophyll is packaged into specialized intracellular "containers" in plants. Decreased water loss C. Increased muscle strength D. Absorption of UV light E. Increased synthesis of vitamins 63. Melanocytes are melanin-producing neural crest-derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, vaginal epithelium, meninges, bones, and heart. The molecule effectively absorbs UV-light and neutralizes damaging molecules (radicals) created by exposure to sunlight. When stimulated by UV light, the total level of which increases in most parts of the world at certain times of year while decreasing in others, melanocytes produce more and larger granules, allowing for people's skin to adapt over the course of the summer and become "tan."

There are two types of keratin, according to Bio-Medicine.org: alpha-keratin, which is abundant in humans and mammals, and beta-keratin that is primarily in birds and reptiles. The lack of melanin production in our body means the faster appearance of grey hairs or even albinism. Melanin is the bodies own way to protect the skin against sunlight . Q 47 . As noted, however, in some people this ability is genetically limited and in some cases nearly absent, while in other people it is essentially superfluous. It also occurs in the zona reticularis of the adrenal gland. Melanocytes are melanin-producing neural crest-derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, vaginal epithelium, meninges, bones, and heart. On the other hand, grey hair is found less (with less eumelanin) in black, brown and/or blonde hair. Since keratin is tough and insoluble in water, the keratinized stratum corneum protects against mechanical injuries, fungal and bacterial attacks, and loss of body moisture.
