- 41. fibers that secure the periosteum to the underlying bone
- 42. immovable joints
- 43. tiny canals that radiate outward from the central canals to all lacunae
- 45. The bones of the limbs and girdles that are attached to the axial skeleton
- 48. The process of creating new blood cells in the body
- 50. dense and looks smooth and homogeneous
- 56. bones that do not fit one of the preceding categories
- 57. also called joints, sites where two or more bones meet
- 59. covers the external surface
- 60. essential if bones are to retain normal proportions and strength during long bone growth as the body increases in size and weight
- 61. realignment of the broken bone ends
- 62. pads of flexible fibrocartilage that cushion the vertebre and absorb shocks while allowing the spine flexibility
- 63. mature bone cells found within the matrix in tiny cavities
- 64. ylindrical end of one bone fits into a trough shaped surface on another bone
