  3. albinism (or albino)
    absence of melanin cells
  4. Epidermis

  5. melanin cells
    the brownish-black pigments of the skin
  6. Freckles
    due to concentrations of melanin.
  7. Hair

    a misnomer for the skin, actually comprised of two different types of tissues
  11. the root, the shaft
    extends above the surface
  12. Nails
    finger and toe nails, are specialized epidermal cells
  13. Dermis
    the inner (internal) primary layer of the skin.  It is composed of Connective tissue.
