Across
  1. 2. type of fracture where one fragment is driven into another
  2. 5. outer surface of the bone that is made with a fibrous membrane
  3. 6. type of fracture where a bone has NOT broken through the skin
  4. 10. foramen small opening in the diaphysis where the blood vessels enter
  5. 12. hormone of the parathyroid gland that regulates the metabolism of calcium and phosphorous in the body
  6. 13. type of fracture where bone is pulled apart in result to a twisting motion
  7. 14. the spaces that osteocytes are located in; found in compact and spongy bone
  8. 15. The end of a long bone, usually larger in diameter than the shaft; filled with spongy bone
  9. 16. Bone marrow where red blood cells, white blood cells, and platelets are all produced.
  10. 18. type of bone that is cube-like shaped and equal in length, wide, and thickness.
  11. 20. partial fracture where only one side of the bone is broken
  12. 22. Center of an osteon that contains blood vessels, nerves, and lymphatic vessels; ; found in compact bone
  13. 23. bone digesting cell
  14. 24. the microscopic structural unit of compact bone; circular structures
  15. 26. The shaft of a long bone.
  16. 29. type of fracture where several breaks result in many small pieces
  17. 30. lattice-like network of matrix spikes in spongy bone where lacunae and osteocytes are found; forms along lines of stress to provide strength to the bone.
Down
  1. 1. channels within the bone matrix that carry nutrients from the central canal to the lacunae; found in compact bone
  2. 3. Rings of calcified matrix that stack together to form an osteon; found in compact bone
  3. 4. bone marrow that contains adipose tissue; the triglycerides stored in the adipocytes of the tissue can serve as a source of energy.
  4. 7. plate AKA the growth plate; a layer of cartilage in a growing bone; later replaced by bone after a person is done growing
  5. 8. type of fracture where a bone has broken through the skin
  6. 9. adult bone cells that are located in the lacunae
  7. 11. type of fracture where the break is straight across the longitudinal axis of the bone
  8. 17. cavity section within the diaphysis which is filled with yellow marrow.
  9. 19. bone forming cell
  10. 21. type of bone that is thin and curved
  11. 25. type of fracture where the break occurs at an angle that is NOT at 90 degrees
  12. 27. type of bone with a complex shape
  13. 28. type of bone that is cylinder in shape and longer than it is wide
