[mel′ənōsīt′, məlen′ōsīt]

Etymology: Gk, melas + kytos, cell

a body cell capable of producing melanin. Melanocytes are distributed throughout the basal cell layer of the epidermis and form melanin pigment from tyrosine, an amino acid. Melanin granules are then transferred to adjacent basal cells and to hair. Melanocyte-stimulating hormone from the pituitary controls the amount of melanin produced.
