2. Which of the following, regarding the melanocyte, isfalse?
a) like all cells in the epidermis, it adjoins neighboringkeratinocytes directly by desmosomal
connections – this ensures all elements of the skin resisttension maximally
b) both eumelanin and pheomelanin made by melanocytes undergofast internal conversion of photoninduced
excitation to heat energy
c) melanosomes made by melanocytes are assembled along theexterior-facing surface of keratinocyte
nuclei
d) the ration of melanocyte to keratinocytes is roughly 1 to 36for majority of the skin surface in
humans
e) relative melanocyte activation and the relative melaninsubtype concentrations largely account of
the astonishing diversity of human skin coloration
