diaphysis
epiphysis
osseophysis
metaphysis
Cells that secrete the organic components of the bone matrix are called

osteoprogenitor cells
osteoblasts
osteoclasts
Through the action of osteoclasts,
new bone is formed
an organic framework is formed

fractured bones regenerate
The interconnecting tiny arches of bone tissue found in spongy bone are called
osteons
interstitial lamellae
concentric lamellae
trabeculae
The medullary cavity of bones contains
osteons
compact bone
periosteum
marrow
Endochondral ossification begins with the formation of a(n)
calcified model
osteoblasts model
cartilage model
membranous model
The following are major steps in the process of intramembranous ossification.
1. Clusters of osteoblasts form osteoid that becomes mineralized.
2. Osteoblasts differentiate within mesenchymal connective tissue.
3. Spicules of bone radiate out from the ossification centers.
4. Mesenchymal cells aggregate.
The correct order for these events is:
2, 1, 3, 4
4, 1, 2, 3
4,2,1,3
2, 3, 1, 4
Secondary ossification centers occur
in the epiphyses
at the periosteum
in the diaphysis
in the metaphyses
