Layers of the Epidermis
  1. Stratum Corneum (20-25 layers)
    1. Layers of keratinocytes
      1. Containment
        1. Water protection
          1. 28 day cycle
            1. 14 to reach SC
              1. 14 to be shed
              2. No nucleus
              3. Squaemous Epithelium
              4. Stratum Granulosum
                1. Contains increasingly kertainised cells
                  1. Keratin organises into fibres
                  2. Lamellar granules produce lipid 'glue
                    1. Some undergo apoptosis
                      1. They're too far from a nutrient source
                      2. Nuclei being to disintegrate
                      3. Stratum Basale
                        1. Basal Cells
                          1. Rapidly dividing
                            1. Keratinocytes
                            2. Merkel Cell
                              1. Associated with sensory nerves
                                1. Shapes/textures
                                2. Found at bottom of sweat duct
                                3. Melanocytes
                                  1. 8-10% of stratum basale
                                    1. Produce melanosomes
                                    2. Apoptosis of these cells under UV causes sunburn
                                  2. Stratum Spinosum
                                    1. Adjacted cells bonded by desmosomes
                                      1. Coarser keratin than in the stratum basalum
                                        1. Limited ability to divide
                                          1. Langerhans Cell
                                            1. Presents antigens of taken up microbes
                                              1. So T-cells will recognize them
