Across
- 8. confined to cavities in the spongy bone of flat bones and the epiphysis of some long bones
- 9. an immovable joint
- 10. flattened fibrous sacs lined with synovial membrane and containing a thin film go synovial fluid
- 12. joints in which the articulating bones ends are separated by a joint cavity containing synovial fluid
- 15. abnormal lateral curvature of the spine
- 16. process of bone formation
- 18. blood cell formation
- 21. ragged break occurs when excessive twisting forces are applied to a bone
- 26. broken bone portion is pressed inward
- 28. essential if bones are to retain normal proportions and strength during long-bone growth as the body increases in size and weight
- 29. thin, flattened, and usually curved
- 30. happens when a bone is forced out of its normal position in the joint cavity
- 32. bones that don't fit any of the other bone categories
- 34. the realignment of the broken bone ends
- 35. bumps, holes, and ridges. reveals where muscles, tendons, and ligaments were attached and where blood vessels and nerves passed
- 37. bone is crushed
- 38. hold the eyes in an anterior position and allow the facial muscles to show our feelings through smiles or frowns
- 40. the bones of the limbs and girdles that are "appendicular" to the skeleton
- 44. bone forming cells
- 45. freely movable joints
- 47. arranged in concentric circles called lamellae
- 48. cover the external surface
- 49. has no body
- 52. the ends of the long bone
- 54. secures the periosteum to the underlying bone
- 56. the spherical head of one bone fits into a round socket in another
- 57. generally cube-shaped and contain mostly spongy bone
- 58. fibrous connective tissue membrane that cover and protects the diaphysis
- 59. the bones are united by fibrous tissue
- 60. the bones that form the longitudinal axis of the body
- 61. contains lamellae around it
- 63. the mature bone cells, are found in the matrix in tiny cavities called lacunae
- 64. bone breaks incompletely, much in the way a green twig breaks
- 65. fibrous membranes connecting the cranial bones
- 66. the cylindrical end of one bone fits into a trough-shaped surface on another bone
- 67. adipose (fat) tissue
- 68. encloses and protects the fragile brain tissue
Down
- 1. the rounded end of one bone fits into a sleeve or ring of bone
- 2. excessive outward curvature of the spine, causing hunching of the back
- 3. acts as a pivot for the rotations of the atlas
- 4. or shaft, makes up most of the bone's length and is composed of compact bone
- 5. drying of the discs, alone with a wearing of the ligaments of the vertebral column
- 6. the articular surfaces are essentially flat, and only short slipping or gliding movements are allowed
- 7. typically longer than they are wide
- 11. allows movement around one axis only
- 13. a flat plate of hyaline cartilage
- 14. movement occurs around two axes
- 17. broken bone ends are pushed into each other
- 19. tiny canals, radiate outward from the central canals to all lacunae
- 20. cushion the vertebrae and absorb shocks while allowing the spine flexibility
- 22. the egg-shaped articular surface of one bone fits into an oval concavity in another
- 23. in adults, the cavity of the shaft is primarily a storage area for adipose tissue
- 24. the sites where two or more bones meet
- 25. each articular surface has both convex and concave areas, like a saddle
- 27. allows movement in all axes, including rotation, and are the most freely moving synovial joints
- 31. run in the compact bone at right angels to the shaft
- 33. the curvatures in the cervical and lumbar regions
- 36. the most common form of arthritis, is a chronic degenerative condition that typically affects the aged
- 39. giant bone-destroying cells in bones
- 41. excessive inward curvature of the spine
- 42. the bone ends are connected by fibrocartilage
- 43. composed of small needle like pieces of bone and lots of open space
- 46. concentric circles around central canals
- 50. slightly movable joints
- 51. bone breaks into many fragments
- 53. the spinal curvatures in the thoracic and sacral regions
- 55. dense and looks smooth and homogenous
- 61. blood-filled swelling
- 62. gliding does not involve rotation around any axis
