The most superficial layer of the skin is the epidermis which is attached to the deeper dermis. Accessory structures, hair, glands, and nails, are found associated with the skin. The deeper layer of skin is well vascularized (has numerous blood vessels) and is superficial to the hypodermics.
6 ημέρες πριν · The outermost layer is the stratum corneum, a thick layer of dead, flattened, keratin-filled keratinocytes that protect the underlying tissues. Dead keratinocytes slough off from the exterior surface of the stratum corneum only to be replaced by new cells emerging from the deeper layers.
4 ημέρες πριν · Outermost Layer: The epidermis is the topmost layer of the skin, responsible for creating a protective barrier. It is made up of keratinized stratified squamous epithelium, meaning it is composed of multiple layers of flat cells that are filled with keratin, a tough, fibrous protein.
The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures.
The epidermis is the relatively thin, tough, outer layer of the skin. Most of the cells in the epidermis are keratinocytes. They originate from cells in the deepest layer of the epidermis called the basal layer. New keratinocytes slowly migrate up toward the surface of the epidermis.
The epidermis is epithelium composed of multiple layers of cells. The basal layer consists of cuboidal cells, whereas the outer layers are squamous, keratinised cells, so the whole epithelium is often described as being keratinised stratified squamous epithelium. LM × 40.
