What two strata are collectively known as the stratum germinativum?

The two strata collectively known as the stratum germinativum are the stratum basale and the stratum spinosum. The stratum basale is the deepest layer of the epidermis, responsible for the generation of new skin cells, while the stratum spinosum provides strength and flexibility to the skin. Together, they play a crucial role in the skin's regeneration and overall health.
