GENERAL HISTOLOGY

Detailed explanation-1: -Melanocytes are derived from neural crest cells and primarily produce melanin, which is responsible for the pigment of the skin. They are found between cells of stratum basale and produce melanin.

Detailed explanation-2: -Melanocytes are in the layer of basal cells at the deepest part of the epidermis.

Detailed explanation-3: -Keratinocytes are present in all four layers of the epidermis. Under physiological conditions, keratinocytes proliferate in the stratum basalis and over a 30–50-day period migrate through the epidermis to the stratum corneum. During this process, these cells undergo significant functional and morphological changes.
