cells of the epidermis kertinocytes, melanocytes, lagerhans calls, merkel cells (produce

formation, and burns that result in the epidermis detaching from the dermis




rete ridges anchors the epidermis to the dermis with dermal papillae in the dermis




epidermis acidic barrier fluctuating between ph 4.5-6.5. protects against bacteria and

environmental pollutants, regulates skins oil and transepidermal water loss (TEWL).




Increased PH corresponds with increased TEWL. highest PH is observed in most hydrated

areas such as skin folds.




transepidermal water loss (TEWL) quantity of water that passes through the eipdermis to

the surrounding atmosphere via diffusion or evaporation.
