This layer consists of flattened dead cells on the surface of the skin containing keratin, a firm, and resilient protein. The layer is translucent because it contains a non-staining biochemical product that will be converted into keratin in the stratum corneum. In stained slides this layer can be seen as a more translucent layer without nuclei. This layer is only seen in thicker layers of epidermis. Provides thickness and strength to withstand friction to the soles and palms. Cells contain densely packed keratin and are connected by desmosomes. Nuclei are dissolving and cells are dying. Stratum lucidum composed of 35 layers of flattened eosinophilic cells, creating a clear or translucent layer located only in the soles of the feet and palms of the hands. These keratinocytes stain darkly with a basic stain because of keratohyalin, a substance being produced in this layer which is an intermediate in the formation of keratin. Epidermal region involved in rapid cell division most inferior epidermal layer Stra m 6. Dermis layer responsible for fingerprints Qerm\s 4. Strata containing all or mostly dead cells PoD\\ \0( \a(3. This layer is so thin that the edges of the cells and some connections of their nuclei cannot be identified. Translucent cells, containing keratin steatvrn COf tlPI' m l'. Also known as the transparent layer, it is located only in the thickest parts of the skin, such as the palms of the hands and the soles of the feet. This is the first transitional stage for the keratinocytes and the cells are nucleated. a translucent cell layer in thick skin containing dead keratinocytes. Keratinocytes of this layer appear to have spinous extensions because the cells are shrinking and compacting while maintaining attachments to surrounding cells. The typical skin cell is the keratinocyte, which, after it has been formed by mitotic division, will undergo some changes as it is pushed toward the surface of the skin. They usually stay there and sometimes flake off. It is also the germinal layer, or layer of cell propagation by mitosis. Dead skin cells are called keratin and are usually packed on the palms of our hands and the soles of our feet. This is the basal, or deepest layer of the epidermis. radiation, absorption, conduction, evaporation 2. dead cells Circle the term that doesn't belong to the group : 1. 1) Stratum Basale (or stratum germinativum) translucent cells, containing keratint 2. Stratum lucidum (in thick epidermis only)Įach of the layers is described briefly below. translucent cells in thick skin containing keratin fibrils stratum lucidum and stratum corneum. is found everywhere on the body except the palms of the hands,soles of the feet,and lips and primarily. Its secretion (often milky in appearance) contains proteins and other substances that favor bacterial growth. The stratified squamous epithelium of the epidermis has 4 or 5 discernable layers in histological sections. A less numerous variety of perspiration glad is.
