<unk> s are keratinocytes without nuclei and cytoplasmic organelles. They contain a highly insoluble cornified envelope within the plasma membrane, and lipids (fatty acids, sterols and ceramides) released from lamellar bodies within the epidermis. The<unk> s are interlocked with each other and organized as vertical columns of 10–30 cells to form the stratum corneum.<unk> s in the lower part of the stratum corneum are bridged together through specialized junctions (corneodesmosomes). Those junctions disintegrate as<unk> s migrate toward the surface of the skin and result in desquamation. At the same time, as those loosened junctions encounter more hydration, they will expand and connect together, forming potential entry pores for microorganisms. The stratum corneum can absorb three times its weight in water but if its water content drops below 10% it no longer remains pliable and cracks.
