- 1. skull
- 5. curving inward of the lower back
- 6. degeneration of joint cartilage and underlying bone usually in hip, knee and thumb joints

- 10. slightly movable joint
- 17. Ends of the long bone
- 19. Slip or glide joints. No axis
- 21. collapse of vertebra due to trauma or weakened vertebra (often seen in people with osteoporosis).
- 22. 14 bones that include:
- 23. nasal concha (2)
- 27. swelling of clotted blood w/in the tissues
- 28. Skull, vertebral column, ribs, and sternum
- 30. 1st cervical vertebra; articulates with the occipital bone of the skull and the second cervical vertebra (axis)
- 33. Condyle- Round prominence at the end of a bone, most often part of a joint. Epicondyle- a projection near a condyle, particularly the medial epicondyle of the humerus
- 34. made up of fat cells
- 36. small needle like pieces of bone and open space
- 38. joint is forced out of normal position
- 39. Annulus fibrosus (outer portion) of the vertebral disc is torn
- 40. Diathroses. surrounds bones' articulating surfaces
- 41. small channel or duct
- 42. Saddle and condyloid. 2 axes at right angles to each other
- 49. Small channels that transmit blood vessels from the periosteum into the bone/ Lie perpendicular to and communicate with the Haversian canals
- 51. synovial joint
- 56. ventrally convex curves of the vertebral column that develop postnatally in the cervical and lumbar regions (lordoses)
- 61. sideways curvature of the spine
- 62. splinter break into more than 2 fragments.
- 63. 2nd cervical vertebra; has a vertical projection called the dens around which the atlas rotates/ imaginary line about which a joint or structure rotates
- 66. Uniaxial. Ankel, elbow and knee
- 68. ovoid articular surface. permits movement of 2 planes
- 69. bones (2)
- 70. blood cell formation that occurs in red bone marrow
- 71. forward rounding of the back
- 72. Central cavity of bone shafts. Red bone marrow and/or yellow bone marrow is stored. Also known as the marrow cavity.
- 73. longer than wide
- 74. rotating force(torque) is applied along the axis of a bone (body in motion, while one part is planted)
- 75. thin layer or plate-like tissue
Down
- 2. Surgery to restore a fracture or dislocation to the correct alignment
- 3. Pivot and hinge joints. Occurs around one axis
- 4. 100's of CT fibers, called perforating fibers, secure periosteum to the underlying bone
- 7. cell that secrets the matrix for bone formation
- 8. bone formation
- 11. bone shaped like a saddle rests on another like a horse. provide stability to bones, while more flexibility than hinge or gliding joint
- 12. bones (2)
- 13. fluid-filled sac-like cavity that counters friction at a joint.
- 14. Red blood cells, platelets and most white blood cells
- 15. Bones of the limbs and limb girdles that are attached to the axial skeleton
- 16. bones (2)
- 18. connected entirely by cartilage (fibrocartilage or hyaline)
- 20. Canal Minute tubes that form a network in bone and contain blood vessels
- 24. sutures in an infant’s skull b/w the cranial bones that make up the calvaria
- 25. Ball and socket. Several axes.
- 26. Non-axial. Slight gliding of 2 flat bone surfaces
- 29. one side of bone is broken and the other bent (children)
- 31. cube-shaped and contain spongey bone
- 32. Fibrous connective membrane that cover the diaphysis
- 35. (2)
- 37. line/plate growth plate, replaced by line when child grows into an adult
- 43. bones (2)
- 44. joint; point where two bones meet
- 45. Have no joint cavity and are connected by fibrous CT. Found in skull bones
- 46. b/w vertebrae
- 47. spherical end lies in a socket (hip or shoulder). allows multidirectional movement and rotation
- 48. fragment is depressed below the normal surface (skull)
- 50. glassy hyaline cartilage that covers its external surface. decreases friction and joint surfaces
- 52. Mature bone tissue is removed from the skeleton (bone resorption) and new bone tissue is formed (ossification)
- 53. one fragment is driven into another
- 54. Shaft in long bones that takes up most of the length and composed of compact bone
- 55. do not fit other categories. Ex: Vertebrae
- 57. Uniaxial. Axis of a convex articular surface is parallel with the longitudinal axis of the bone
- 58. ventrally concave curve of the fetal vertebral column in the thoracic and sacral regions (kyphosis)
- 59. fixed joint b/w bone
- 60. thin, flattened and usually curved
- 64. cavity or depression
- 65. dense, smooth, homogeneous
- 67. bone cell that is formed when an osteoblast becomes embedded in the matrix it has secreted
