GENERAL HISTOLOGY

Detailed explanation-1: -The basal layer is the innermost layer of the epidermis, and contains small round cells called basal cell s. The basal cells continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed.

Detailed explanation-2: -The stratum basale is a single layer of cells primarily made of basal cells. A basal cell is a cuboidal-shaped stem cell that is a precursor of the keratinocytes of the epidermis. All of the keratinocytes are produced from this single layer of cells, which are constantly going through mitosis to produce new cells.

Detailed explanation-3: -The epidermis is attached to the dermis via a basement membrane. The topmost layer of the dermis is called the papillary layer. This layer is composed of connective tissue that contains extensions which extend into the epidermis. This holds the two layers together.
