Final answer:
The Stratum Basale is the deepest epidermal layer composed of a single layer of basal cells which regenerate the epidermis.
Step-by-step explanation:
The Stratum Basale consists of a single layer of basal cells. These cuboidal-shaped stem cells are responsible for producing all keratinocytes in the epidermis, which are pushed upward as new cells are formed. The Stratum Basale is also home to melanocytes which produce melanin, and to touch-sensitive Merkel cells.
This layer is the deepest part of the epidermis and is crucial for the regeneration of the skin. It is made up of a single layer of cells primarily composed of basal cells, which are cuboidal-shaped stem cells. These basal cells continuously divide to produce all the keratinocytes of the epidermis. Therefore, the stratum basale is a single layer of cells.
