which layer of the epidermis is not found in all types of human skin?
stratum lucidum
epidermis is divided into several layers where cells are formed through mitosis at the innermost layers. they move up the strata changing shape and composition as they differentiate and become filled with keratin. they eventually reach the top layer called "stratum corneum" and are sloughed off, or desquamated. this process is called "keratinization" and takes place within weeks. the outermost layer of the epidermis consists of 25 to 30 layers of dead cells.

human skin
the human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis. (the hypodermis or subcutaneous layer is not part of the skin.) the epidermis is the outermost layer, providing the initial barrier to the external environment.it is separated from the dermis by the basement membrane. the epidermis contains melanocytes and gives color to the skin. the deepest layer of epidermis also contains nerve endings. beneath this, the dermis comprises two sections, the papillary and reticular layers, and contains connective tissues, vessels, glands, follicles, hair roots, sensory nerve endings, and muscular tissue. the deepest layer, the hypodermis, is primarily made up of adipose tissue. substantial collagen bundles anchor the dermis to the hypodermis in a way that permits most areas of the skin to move freely over the deeper tissue layers.
