Which epidermal layer has a high concentration of dendritic (Langerhans') cells and has numerous
desmosomes?
Stratum corneum
Stratum lucidum
Stratum granulosum
Stratum basale
Stratum spinosum
Keratinocytes are the major cellular components of the epidermis. They are found in the four major epidermal strata: basale, spinosum, granulosum and corneum. Explain the characteristics of and the changes in the keratinocytes as they journey from the deepest to the most superficial epidermal strata.
Match each epidermal layer in column B to its description in column A.Column A Column B(1) Desmosomes and shrinkage artifacts give its cells “spiny”projections. (a) stratum basale(2) Its cells are flat, dead bags of keratin. (b) stratum corneum(3) Its cells divide, and it is also called the stratum germinativum. (c) stratum granulosum(4) It contains keratohyalin and lamellated granules. (d) stratum lucidum(5) It is present only in thick skin. (e) stratum spinosum
