Epidermis - 5 Layers of Epidermis, Outermost Layer & Functio

Layers of the Epidermis. The epidermis of thick skin has five layers. Beginning at the basal lamina and traveling superficially toward the epithelial surface, we find the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. Refer to Figure 2 as we describe the layers in a section of thick skin. Stratum Basal Epidermis, in zoology, protective outermost portion of the skin.There are two layers of epidermis, the living basal layer, which is next to the dermis, and the external stratum corneum, or horny layer, which is composed of dead, keratin-filled cells that have migrated outward from the basal layer.The melanocytes, responsible for skin colour, are found in the basal cells

Stratum corneum is the outermost layer of the epidermis. It consists of 10 to 30 layers of dead keratinocytes that are constantly being shed. Shedding of these cells slows significantly with age. The complete cell turnover, from basal cell to stratum corneum, takes around four to six weeks for young adults and about a month and a half for older. The epidermis, which is the topmost layer, actually has 5 sub-layers. The stratum basale is the deepest layer, while the stratum corneum is the outermost layer of epidermis. Bodytomy takes a closer look at these layers along with their functions

  1. Epidermis in rest of the body has only 4 layers. Stratum Corneum (horny layer) : Most superficial layer. Cells are fully keratinised and end up as anucleate dead cells which later desquamate. Basale, spinosum and granulosum together are called as the living layer. Corneum is called as the dead layer
  2. Epidermis: The upper or outer layer of the two main layers of cells that make up the skin. The epidermis is mostly made up of flat, scale-like cells called squamous cells. Under the squamous cells are round cells called basal cells. The deepest part of the epidermis also contains melanocytes
  3. Layers of the epidermis: The epidermis is made up of 95% keratinocytes but also contains melanocytes, Langerhans cells, Merkel cells, and inflammatory cells. The stratum basale is primarily made up of basal keratinocyte cells, which can be considered the stem cells of the epidermis
