Detailed explanation-1: -The epidermis consists of several layers beginning with the innermost (deepest) stratum basale (germinatum), followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and ending with the outermost layer, the stratum corneum.
Detailed explanation-2: -The epidermis is the top layer, and the dermis is the middle layer. The dermis exists between the epidermis and the hypodermis. While the epidermis is the thinnest layer of skin, the dermis is the thickest layer of skin.
Detailed explanation-3: -The layers of the skin from deep to superficial are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. This is the order from deep to superficial, with the stratum basal being the deepest layer and the stratum corneum being the most superficial.
Detailed explanation-4: -The stratum basale (also called the stratum germinativum) is the deepest epidermal layer and attaches the epidermis to the basal lamina, below which lie the layers of the dermis. The cells in the stratum basale bond to the dermis via intertwining collagen fibers, referred to as the basement membrane.
