Across
  1. 3. Lines which are defined by collagen orientation that have key implications for design & placement of surgical incisions
  2. 6. Thin plate of dead stratum corneum containing very hard keratin
  3. 9. Skin layer which has 5 'strata'
  4. 14. Type of melanin which provides poorer UV protection & greater vitamin D production
  5. 17. Cells which form the apical layer of epidermis
  6. 18. Large concentric rings of fibroblast cells separated by gelatinous fluid, surrounding a nerve ending
  7. 19. Has 2 main layers, namely papillary and reticular
  8. 20. Alternately known as tactile cells found in the basal layer
  9. 22. Thickest layer that has corneocytes glued together by a lipid matrix
  10. 23. Smooth muscle which contracts/dilates based on these muscles in the hair
  11. 24. Alternately known as stretch marks
Down
  1. 1. Has squamous keratinocytes
  2. 2. Process of the exocrine gland that uses exocytosis
  3. 4. Glands which excrete sebum (oily lipids) into hair follicle
  4. 5. Unit Hair follicle + sebaceous glands + apocrine sweat gland.
  5. 7. Alternately known as subcutaneous tissue
  6. 8. First dead cell layer
  7. 10. Lines which enhance grip & sensation
  8. 11. Has intercellular spinous cytoplasmic projections
  9. 12. Cells which product melanin
  10. 13. Process where cell surface breaks off, moves away
  11. 15. Located in the dermis with randomly coiled structure with a rubbery, resilient quality
  12. 16. Dermal folds at/near synovial joints to allow for movement
  13. 21. Located in the dermis to cross-link to provide good tensile strength
