DIRECTIONS: Match the letter of the description and/or function to the epidermal layer that defines it. A. Outermost layer of dead keratinocytes that protect the skin 6. Stratum basale B. Layer of skin composed of areolar and dense irregular connective tissues 7. Stratum spinosum C. Layer of keratinocytes that undergo apoptosis via keratinization 8. Stratum granulosum D. Single layer of active stem cells that undergo somatic cell division 9. Stratum lucidum E. Layer of skin composed of adipose and areolar connective tissue 10. Stratum corneum F. Layer of keratinocytes with intermediate filaments to resist tension G. Layer of clear, flat, dead keratinocytes found only in thick skin

Which layer of the epidermis contains dead cells filled with keratin? Stratum lucidum Stratum basale Stratum spinosum Stratum corneum Stratum granulosum
