The function of the Epidermis is to?

• Provide a protective layer
• Determine skin color
• Prevent water loss
• All of the above

Keratinization is the process of

• Creating Melanin and determining skin color
• Going from a living cell to a dead cell filled with keratin
• Regulating temperatures
• Creating Vitamin D

In the stratum basale, what step of keratinzation is underway?

• The cells are living and dividing.
• The cells have begun to become spiny and are creating Keratin.
• The cells have created so much keratin that little granules can be seen.
• The cells are dead and filled with keratin.

In the stratum spinosum, what step of keratinzation is underway?

• The cells are living and dividing.
• The cells have begun to become spiny and are creating Keratin.
• The cells have created so much keratin that little granules can be seen.
• The cells are dead and filled with keratin.

In the stratum granulosum, what step of keratinzation is underway?

• The cells are living and dividing.
• The cells have begun to become spiny and are creating Keratin.
• The cells have created so much keratin that little granules can be seen.
• The cells are dead and filled with keratin.
