9) Thick skin is found on palms, palmar surfaces of digits, and soles, while thin skin is found in all other areas. Thick skin is 4-5 thicker than thin skin. The stratum lucidum is present exclusively in thick skin. Also, the stratum spinosum and stratum corneum are thicker in thick skin. Thick skin exhibits epidermal ridges, more sweat glands and a higher density of sensory receptors. Thin skin has hair follicles and sebaceous glands, while thick skin does not.

10) Multiple layers of cells in stratified squamous epithelium help resist friction. Keratin of intermediate filaments provides strength to tissue by binding cells tightly together and to underlying tissue, thus creating a barrier to microbes. Lamellar granules of keratinocytes produce a lipid rich, water repellent (sealant) to protect from dehydration and entry of foreign materials. Melanin, produced by melanocytes, protects underlying tissue from UV light. Sebum secreted onto the surface helps protect from dehydration and microbial invasion. Intraepidermal macrophages (Langerhans cells) participate in immune response to microbial invasion.
