Answer 1

ANSWER : A)

1. Translucent cells, containing keratin --- stratum lucidum

2. Strata contain all or mosty dead cells --- Stratum corneum

3. Dermis layer responsible for fingerprints --- papillary layer

4. Vascular region --- Dermis as a whole

5. Epidermal layer involve in rapid cell division and most inferior epidermal layer --- stratum basale

6. Scale-like cells full of keratin that cinstacons flake off --- stratum corneum

7. Site of elastic and collagen fibres --- reticular layer

8. Site of melanin formation --- stratum basale

9. Major skin area from which the derivatives (hair and nail) arise --- epidermis as a whole

10. Epidermal layer containing the oldest cells --- stratum corneum

11. When tanned become leather --- Dermis

ANSWER : B)

1. Keratin found in epidermal layers

2. Wart is the small fleshy bump on the skin

3. Stratum basale is the most inferior layer of epidermis and produce all the remaining layers

4. Keratinocytes produce keratin in the cells of epidermis

5. Arrector pili are the muscles present in the dermis layer and associated with body hair movement

6. Waterproof substance (lamellated granules) produced via stratum granulosum  

7. Lamellated granules of stratum granulosum layer produce a waterproof glycolipid.
