several layers thick (3-5)
keratinocytes are starting to make pre keratin - thick bundles

flat filled with keratin
glycolipids in extracellular space

127
Q

if there is an extra layer of tissue in the epidermis what is it called and what does it look like

A

lucidam - provides protection often in hands and feet due to needed coverage for extra wear and tear
cells are transparent and clear but can appear white at the surface at times

128
Q

lower level of the skin - much thicker then the epidermis

split into two layers papillary layer and reticular level

129
