How many number of keratinocytes per melanocyte form an epidermal melanin unit?
assistant
The correct answer is  Melanocytes are present in the basal layer of the epidermis and their dendrites interdigitate with keratinocytes. A melanocyte with a number of associated keratinocytes (about 36) forms an epidermal melanin unit. Melanocytes contain discrete organelles called melanosomes, which synthesize melanin. There are two types of melanin: Brown-black eumelanin is present in spherical melanosomes. Red-brown or yellow pheomelanin is present in ovoid melanosomes. Once formed, the melanosomes are injected into the keratinocytes by dendrites of melanocytes. Ref:-Neena khanna; pg num:- 145,146
