Multilayered Stratified Keratinizing Squamous Epithelium—Palm of the Hand

The palm of the hand is subject to considerable wear and tear. Because of this stress, the epidermis is tightly attached to the dermis (corium). The epidermis also consists of more layers and is more cornified than the thin epidermis. Note the thick stratum corneum 1 , the abundant epidermal processes 2 and the configuration of the corium papillae 3 . Intact cells with nuclei do not exist in the stratum corneum (keratin layer).
