Skin cells start in the stratum spinosum and move up the stratum granulosum, then to the stratum licidum, and stratum corneum. This is the epidermis inside out layers and growth process.

What occurs in the stratum germinativum layer?
stratum germinativum layer is the deepest layer of five epidermis layer which is the outer covering of skin in mammals. It is a continuous layer of cells which is often described as one cell thick but to the reality it is two to three cells thick in glabrous skin and hyper proliferative epidermis.
Why do you continuously shed dead skin and keratin?
You shed dead skin cells because your body is constantly producing new skin cells, and the new skin cells push older ones farther and farther away from blood supply and oxygen, causing them to die. Dead skin cells aren't that useful, and space is needed for the skin cells that are still alive, and that's why the deal cells are shed, along with the keratin that is in them. If we didn't shed our skin cells, we would have nasty, thick skin.
Skin cells have how many pairs of chromosomes?

What is the principle role of keratin?
Keratin is a protein that is found throughout the human body in nails, teeth, hair, and skin. The primary role of keratin is to promote strength and elasticity in skin. When keratin cells move to the surface of ones skin, the keratin cells die and form a protective layer around the skin. These dead keratin cells are shed as dead skin cells, while more keratin cells move to the surface and die to replace this protective layer.

What are polygonal cells?
Polygonal cells are cells with at least 5 sides; they may have more sides, but not less. The stratum spinosum in the skin is an example of a location with polygonal cells.
Is the stratum spinosum the first line of defense?
No, the stratum corneum is the first line of defense in the skin against pathogens. It consists of a layer of dead keratinized cells that provide waterproofing and protect underlying layers of skin.
