Detailed explanation-1: -The inner layer, called the basal layer (or stratum germinativum), is a germinal epithelium that gives rise to all the cells of the epidermis (Figure 12.32). The basal layer divides to give rise to another, outer population of cells that constitutes the spinous layer.
Detailed explanation-2: -Cell division occurs in stratum basale/germinativum.
Detailed explanation-3: -The stratum germinativum is the layer of the epidermis that is closest to the basement membrane, which is a thin sheet of fibers between the epidermis and the dermis. Above the stratum germinativum is the stratum spinosum.
Detailed explanation-4: -The stratum basale, also called the stratum germinativum, is the basal (base) layer of the epidermis. It is the layer that’s closest to the blood supply lying underneath the epidermis. This layer is one of the most important layers of our skin.
