MICROANATOMY

Detailed explanation-1: -Humans generally have the same amount of melanocytes; the amount of melanin that those melanocytes produce, however, is what varies. Melanin protects the skin by shielding it from the sun.

Detailed explanation-2: -Melanocytes are pigment-producing cells and their key regulating transcription factor is the melanocyte specific microphthalmia-associated transcription factor (m-MITF). Ultraviolet (UV) radiation is a unique modulator of skin pigmentation influencing tanning pathways.

Detailed explanation-3: -Melanocyte is a highly differentiated cell that produces a pigment melanin inside melanosomes. This cell is dark and dendritic in shape. Melanin production is the basic function of melanocyte.
