Strata of the Epidermis

Takes 15 to 20 days for a cell to move from Stratum Basale to......

How long do the cells stay in Stratum Corneum ??

Water resistant, but not waterproof

Dead cells stay connected and shed in large groups

Thickest Layer

Outer layer of both thin and thick skin

Cells are flattened, densely packed, largely developed organellles and filled with Keratin

Found in thick skin

Cells bgin to die

Keratin is produced in large amounts which allow cells to grow thinner and flatter

their membranes become thicker and less permeable

Cells have stopped dividing at this level

Contains dendritic cell, which participles in the immune response by the stimulating defense

Mitosis of new skin cells

Ridges on the palms and soles increase surface area of the skin and increases friction for grip

The ridges and papillae nerve increase surface area for the dissusion of nutrients

Inner most layer

Also known as the Stratum Germinativum
