What is "stratum basale"?

The stratum basale is the innermost layer of the epidermis, composed of basal cells that actively divide and give rise to new skin cells. It serves as a crucial part of the skin's regenerative process, providing a constant supply of cells that migrate upwards to replenish the upper layers of the epidermis. The stratum basale also contains melanocytes, which produce the pigment melanin responsible for skin coloration and protection against harmful UV radiation.

Examples

1. Starting from the deepest layer and working out, there is the Stratum Basale, the Stratum Spinosum, the Stratum Granulosum, the Stratum Lucidum and the Stratum Corneum.
