Английский язык для медиковStratum spinosum is a multilaminar layer of cuboidallike cells that are bound together by means of numerous cytoplasmic extensions and desmosomal junctions. Stratum granulosum consists of flat polygonal cells filled with basophilic keratohyalin granules. Viewed at the electron microscopic level, these cells also contain numerous mem branecoating granules. Stratum corneum is the superficial stratum of dead cells and consists of several to many layers of flat, anucleated, and cornified (keratinized) cells. In the epidermis of the palms and soles, a thin, transitional zone of flat eosinophilic or palestaining anucleated cells may occur as the stratum lucidum. This layer is found only in regions with a thick strata corneum. Cells of the epidermis: keratinocytes are the most numerous and are responsible for the production of the family of keratin proteins that provide the barrier function of the epidermis. Melanocytes are derivatives of neural crest ectoderm. They are found in the dermis and are also scattered among the keratinocytes in the basal layers of the epidermis ...» |
