Factors regulating growth |
|
-Growth Process
- Replacement of preexiting tissues with bone |
Ossification |
|
Major structural unit of compact bone.
-Contains cylindrical layers of osseous tissue(LAmellae) |
Osteons |
|
-Short region between diaphysis and epiphysis
|
Metaphysis |
|
1/3 organic (proteins, lipids, cells)-osteocytes, collagen fibers.
2/3 Matrix(hydroxyapatite) |
Bone Composition |
|
Bone growth process
-deposition of calcium salts in tissue, fills in matrix around lacunae |
Calcification |
|
Osteon cement
|
Calcium |
|
_Bone tissue type
-Open network of branching plates called trabeculae - forms middle regions of bone -lacks osteons |
Spongy Bone |
|
1-chondrocytes make carilage
2)calcium phosphate adds to matrix 3)cartilage cells organize into osteons 4)cartilage cells convert into osteocytes 5)bone tissue formed |
