Final answer:
The basal cell layer of the epidermis is referred to as the stratum basale, which is the deepest layer that attaches to the basal lamina through the basement membrane and contains stem cells known as basal cells.
Step-by-step explanation:
Stratum basale is another name for the basal cell layer of the epidermis. The deepest layer of the epidermis, known as the stratum basale or stratum germinativum, is where the epidermis attaches to the basal lamina. The dermal layers are located beneath the basal lamina. Collagen fibers, which are a component of the basement membrane, are woven together by the cells in the stratum basale to help them stick to the dermis. Furthermore, the cuboidal stem cells known as basal cells are found in this layer and are in charge of generating the keratinocytes that make up the epidermis. These stem cells divide and give rise to new cells that ultimately move upwards through the different layers of the epidermis.
Dermal papillae are a distinctive characteristic of the interface between the epidermis and dermis. These projections, which resemble fingers and are located in the dermal layer's superficial layer, strengthen the bond between the epidermis and dermis. The stronger the connection, the more folding these dermal papillae provide.
