What is the deepest layer of the epidermis more commonly called?

  1. Basal cell layer

  2. Stratum corneum

  3. Stratum granulosum

  4. Epidermis

The correct answer is: Basal cell layer

The deepest layer of the epidermis is commonly known as the basal cell layer because it is the layer where the basal cells, responsible for the constant production of new skin cells, are located. The other options, B, C, and D, are all incorrect because they refer to other layers of the epidermis. B, the stratum corneum, is the outermost layer of the epidermis and is composed of dead skin cells. C, the stratum granulosum, is the layer above the stratum corneum and is responsible for helping to create a protective barrier for the skin. D, epidermis, is the overall name for the outermost layer of the skin, which includes the stratum corneum, stratum granulosum, and the basal layer.
