Across
  1. 3. Nail may grow back irregular
  2. 4. The folds of living tissue/skin on either side of the nail bed and plate. The purpose on the lateral nail folds is to keep bacteria out of the sides.
  3. 7. More defined "C-curve" in the free edge.
  4. 11. The tracks that the nail plate moves on as it grows: the grooves are created by the lateral nail folds of the skin.
  5. 14. The area where the nail plate rests. The nail bed is the support structure for the nail plate. Nerves and blood vessels are found here. Which supplies nourishment to the nail.
  6. 15. Creates nail cells that harden and flatten as they move outward to form the nail plate. The matrix is below the PNF and is where growth originates.
  7. 17. The fingertip or toe tip bone that gives structure to the finger or toe. It helps give shape to the nail matrix, which in turn shapes ine nail plate (matrix length, width, curvature and thickness.
  8. 21. Nail will grow back normally
  9. 22. The front portion of the nail matrix that creates a half-moon shape at the base of the nail plate. It appears lighter in color when visible, but for some, the lunula is under the PNF and can't be seen. The nail plate cells in this area are softer, thinner and much easier to penetrate through to the underling nail bed. Proper care durina a manicure is important to preserve the nail plate.
  10. 23. Attach the nail bed to the bone.
  11. 24. The area underneath the free edge that creates a seal to prevent bacteria from entering the nail bed. Sometimes it can attach to the underside at the tree edge and extend past the tingertip, requiring maintenance or special attention.
Down
  1. 1. The part of the nail plate that extends beyond the finger or toe and protects the tips of the fingers and toes.
  2. 2. The nail plate extends from the matrix to the free edge and is made of lavers of hard, nonliving. keratinized nail cells, with no nerves or blood vessels. There are three main sections within the nail plate: the lower layers, middle layers and upper layers
  3. 5. Flatter free edge.
  4. 6. The thin, pliable, colorless laver of nonliving tissue that has been shed by the specialized cells in the eponychium. It attaches to the nail plate, creating a seal between the PNF and the nail plate, which helps keep bacteria out of the nail matrix area.
  5. 8. Nail may not grow back
  6. 9. matrix Thicker nail plate.
  7. 10. Specialized tissue that adheres to the nail plate through interlocking grooves. These grooves allow the nail plate to glide along the epithelium during nail growth, while keeping the nail plate secure in place.
  8. 12. The fold of skin at the base above the nail plate. It extends from the first joint of the finger to the visible nail plate, back under the skin, to the nail matrix. It’s job is to protect the matrix.
  9. 13. The area where the PNF meets the nail plate; this skin has been keratinized, which hardens the skin cells and creates a barrier against harmful bacteria and chemicals. This portion is living tissue and cannot be clipped.
  10. 16. Contains lymph, blood vessels and nerves that create nail cells.
  11. 18. The live tissue at the underside portion of the PNF covering the new growth of the nail plate; houses specialized stem cells that create the cuticle.
  12. 19. matrix Thinner nail plate.
  13. 20. Appears as a glassy, grayish band at the point where the nail plate meets the hyponychium and halos keen the hyponvehium sea intact. Also called the natura smile line.
