Across
- 1. first visual evidence of interaction between dermis and epidermis
- 5. type of cell that are an extension of the body's immune system
- 7. cells contain keratohyalin granules in this layer of skin, new lamellar granules become more active
- 11. trimester where significant growth occurs, volar padd regression, minutiae set, and sweat ducts and pores
- 15. transient swellings of tissue under the epidermis on hands and feet
- 16. the primary cell of the epidermis
- 17. tissue of volar pads
- 20. outerlayer acts as a receptor organ
- 22. cell proliferatoins resulting in downfolds of the basal epidermis
- 24. by this many weeks EGA the joints of the hand have formed and appear similar in proportion to that of an infant
- 25. keratinocytes undergo an abrupt transition in this layer, cells are keratinized and have completed their programmed cell death
- 26. percent of palms that have no pattern in the hypothenar
- 27. only appendage of the friction ridge skin
- 29. high, symmetrical pads tend to make this pattern with high ridge count
- 32. when volar pads are overtaken by the faster growth of the larger surrounding surface
- 34. mad by low volar pads
- 35. area of the foot with the hightest prevalence of classifiable patterns
Down
- 2. lamellar granules appear in cells as they are pushed toward the limit of this layer of skin, shape becomes more rectangular
- 3. layer of connective tissue
- 4. type of cell that are an extension of the nervous system and participate in the transmission of the sensation of touch
- 6. growth of hands and feet, regular flexion creases, volar pads
- 8. innermost layer of epidermis
- 9. produce the pgments that are deposited into the keratinocytes
- 10. link basal cells to dermis
- 12. shape of volar pad that tend to make loops
- 13. regions of divergence or convergence
- 14. drive the timing of the ridge development
- 18. malleable, peglik projections of the papillary dermis between the primary and secondary ridges
- 19. loose connective tissue made of fat cells and serve as energy reserve
- 21. first volar pad to appear
- 23. the significant epidermal layer that allows skin to act as a major barrior, brick and mortar model
- 28. trimester where mainly a period for protected growth for the fetus
- 30. remnants of dermis left projecting upward into the epidermis when anastomoses bridge primary and secondary ridges
- 31. first creast to appear around 8 weeks EGA followed by flexion creases in fingers
- 33. shape of volar pad that tend to make whorls
