Thick skin: covers areas of abrasion palms, feet consists of five layers. Attached to the underlying dermis along a wavy border. Stratum spinosum: tension- resisting bundles of pre-keratin filaments. Cytoplasm full of lamellar granules and keratohyaline granules. Stratum lucidum: *** only thick skin 2-3 rows of clear, flat, dead keratinocytes. Stratum corneum: thickest, dead cells, flat membranous sacs filled with keratin.
