A layer of the epidermis above the stratum basale where keratinocytes begin producing keratin and develop spiny connections.
A thin, clear layer of dead skin cells found only in thick skin areas like palms and soles.
A layer of the epidermis where keratinocytes accumulate granules of keratohyalin, beginning the process of keratinization.
The primary cell type in the epidermis responsible for producing keratin, a protective protein.

Cells in the epidermis that produce melanin, the pigment responsible for skin color and UV protection.
The thick layer of skin beneath the epidermis containing blood vessels, nerves, and connective tissue.
