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: -The stratum germinatum (SG) provides the germinal cells necessary for the regeneration of the layers of the epidermis. These germinal cells are separated from the dermis by a thin layer of basement membrane.

Detailed explanation-3: -The epidermis includes five main layers: the stratum corneum, stratum lucidium, stratum granulosum, stratum spinosum, and stratum germinativum.

Detailed explanation-4: -The innermost layer of the epidermis is the stratum basale, which contains basal cells and melanocytes. The next layer is the stratum spinosum, which is the thickest of the layers and contains Langerhans cells as well as spiny keratinocytes.
