  1. Specialized Cells of the Epidermis

  2. 2. Melanocytes: Found deep in the epidermis, as melanin is made it accumulates in granules called melanosomes. • Exposure to sunlight can also increase the amount of melanin produced.

  3. Skin color • 3 pigments • Melanin • Carotene • Hemoglobin

  4. Keratinocytes • Most abundant. • Pushed up by the building of new cells. At the surface they are dead. • You lose millions per day and produce a new epidermis every 25-45 days. • In body areas with lots of friction and use epidermis production is faster.

  5. Langerhans’ cells • Star shaped phagocytes • Activate immune system!

  6. Merkel Cells • Touch receptors! • Where the dermis meets the epidermis
