Stratum spinosum (epidermis
3-5 layers of flat keratinocytes; more in thick skin than thin; contains dark staining keratohyalin granules
Stratum granulosum (epidermis)
Seen only in thick sckin, keratinocytes densely packed with eleidin; no nuclei or organelles
Stratum lucidum (epidermis)
Up to 30 layers of dead, scaly, keratinized cells to form durable surface layer; resistant to abrasion, penetration, and water loss
Stratum corneum (epidermis)
Connective tissue layer; hair follicles and nail roots embedded here
Thin zone of areolar tissue in and near dermal papillae; allows for movement of leukocytes and other defenses against things that break through epidermis
