Across
  1. 2. are the ends of the long bone; 2 types are proximal and distal

  5. 11. most common form of arthritis; a chronic degenerative condition that typically affects the aged
  6. 12. tiny canals, radiate outward from the central canals to all lacunae; form a transportation system that connects all of the bone to the nutrient supply through the hard bone matrix
  7. 13. type of fracture in which the bone is crushed
  8. 16. red blood cells, platelets, and most of the white blood cells arise here
  9. 17. slightly movable joints
  10. 19. a disease in which Uris acid accumulates in the blood and may be deposited
  11. 20. type of joint in which each articulate surface has both convex and concave areas, like a saddle
  12. 22. bone-forming cells
  13. 25. movements occur around two axes
  14. 27. blood cell formation
  15. 32. bone ends are connected by fibrocartilage
  16. 33. forward rounding of the back
  17. 34. type of bone that's typically longer than they are wide
  18. 35. type of joint in which the spherical head of one bone fits into a round socket in another
  19. 36. type of bone that's hard to classify with their shape
  20. 38. sideways curvature of the spine
  21. 39. hundreds of connective tissue fibers that secure periosteum to underlying bone
  22. 41. encloses and protects the fragile brain tissue
  23. 43. freely movable joints
  24. 45. type of bone that's dense and looks smooth and homogenous
  25. 46. an autoimmune disease, a disorder in which the body's immune system attempts to destroy its own tissues
  26. 49. covers the external surface; provides a smooth, slippery surface that decreases friction at joint surfaces
  27. 50. allow movement around one axis only
  28. 51. middle of the bone and lined by the endosteum; cavity of the shaft
  29. 54. type of fracture in which ragged break occurs when excessive twisting forces are applied to a bone
  30. 55. crunchy, creaky noise made by joints when moved
  31. 56. (C2); acts as a pivot for the rotation of the atlas (and skull)
  32. 57. hold the eyes in an anterior position and allow the facial muscles to show our feelings through smiles and frowns
  33. 59. cavities with osteocytes; concentric rings
  34. 62. type of joint in which the articulate surfaces are essentially flat, and only short slipping or gliding movements allowed
  35. 63. spinal curvatures in the thoracic and sacral regions, they were present when born
  36. 64. aman perforating canal; perpendicular to the central cavity
  37. 67. no joint cavity and are connected via fibrous connective tissue
  38. 69. type of fracture in which bone breaks into many filaments
  39. 71. joint inflammation
  40. 72. joints in which the articulating bone ends are separated by a joint cavity containing synovial fluid
  41. 74. makes up most of the bones length and is composed of compact bone
  42. 76. flattened fibrous sacs lined with synovial membrane and containing a thin film of synovial fluid
  43. 77. process of bone formation
Down
  1. 1. basically connective tissue that covers the outside of the bone; outside covering of diaphysis
  2. 3. throes immovable joints
  3. 5. a bone-thinning tissue disease
  4. 7. a flat plate of hyaline cartilage seen in young, growing bone
  5. 8. mainly made up of fat cells
  6. 10. joints; sites where two or more bones meet; holds bones together and gives the rigid skin mobility
  7. 14. happens when a bone is forced out of its normal position in the joint cavity
  8. 15. (C1); has no body; allows your to nod "yes"
  9. 18. "water on the knee," due to inflammation of bursae or synovial membrane
  10. 21. type of fracture in which the bone breaks completely
  11. 23. allow movement in all axes including rotation and are the most freely moving synovial joints
  12. 24. fibrous membranes connecting the cranial bones
  13. 26. skeleton in which the overall function is movement of the body; composed of 126 bones of limbs and pectoral and pelvic girdle
  14. 28. curvatures in the cervical and lumbar regions, develop sometime after birth
  15. 29. giant bone-destroying cells in bones
  16. 30. type of bone that's composed of small needlelike pieces of bone and lots of open space
  17. 31. extra bone tissue that grows around the margins of the eroded cartilage and restricts joint movement
  18. 37. realignment of broken ends
  19. 40. type of bone that's just as long as they are wide
  20. 42. cushion the vertebrae and absorb shocks while allowing the spine flexibility
  21. 44. surfaces of its transverse processes contain large depressions that receive the occipital condyles of the skull
  22. 47. aka central canal; opening in center of an osteon and carries blood vessels and nerves
  23. 48. a blood-filled swelling in tissues
  24. 52. skeleton that forms the longitudinal axis of the body; functions as protection of the body
  25. 53. essential if bones are to retain normal proportions and strength during long-bone growth as the body increases in size and weight
  26. 58. reveal where muscles, tendons, and ligaments were attached and where blood vessels and nerves passed
  27. 60. curving inward of the lower back
  28. 61. ,any result when the vertebral column is subjected to exceptional twisting forces
  29. 65. type of joint in which the rounded end of one bone fits into a sleeve off ring of a bone
  30. 66. type of joint in which the egg-shaped articulate surface of one bone fits into an oval concavity in another
  31. 68. formed when an osteoblast becomes embedded in the matrix it has secreted
  32. 70. type of bone that's thin, flattened, and usually curved
  33. 73. type of fracture in which broken bone ends are forced into each other
  34. 75. the ligaments or tendons reinforcing a joint are damaged by excessive stretching, or they are torn away from bone
