Where does Intra-Membranous Ossification Occur?
|
Skull
Mandible Clavicle |
|
|
Bone forms with a fibrous model or template
|
Intra-Membranous Ossification
|
|
|
Step 1 of Intra-Membranous Ossification
|
Osteoprogenitors turn into Osteoblasts
|
|
|
Step 2 of Intra-Membranous Ossification
|
Osteoblasts make Collagen fibers in matrix, calcifying the matrix
|
|
|
Step 3 of Intra-Membranous Ossification
|
once matrix is calcified it turns into Trabeculae
|
|
|
Where do Osteoblasts become Osteocytes?
|
In the Trabeculae
|
|
|
Endochondrial Ossification
|
replacement of Hyaline Cartilage model by bone tissue
|
|
|
Step 1 of Endochondrial Ossification
|
Mesenchymal cells develop into Chondroblasts, which forms cartilage model
|
|
|
Step 2 of Endochondrial Ossification
|
Growth of cartilage model occurs by cell division of chondrocytes
|
|
|
Primary Ossification occurs in the ______________.
|
Diaphysis
|
|
|
Step 1 of Primary Ossification
|
Artery enters the diaphysis
|
|
|
Step 2 of Primary Ossification
|
Cartilage cells start to die
|
|
|
Step 3 of Primary Ossification
|
The matrix starts to calcify
|
|
|
Step 4 of Primary Ossification
|
Osteoprogenitor cells from the Periosteum turn into osteoblasts
|
|
|
Step 5 of Primary Ossification
|
Osteoblasts start making bone
|
|
|
Step 6 of Primary Ossification
|
dense bone in diaphysis is made
|
|
|
Step 7 of Primary Ossification
|
Osteoclasts hallow out & form medullary cavity
|
|
|
Secondary Ossification occurs in the _______________.
|
Epiphysis
|
|
|
Step 1 of Secondary Ossification
|
Artery enters the epiphysis
|
|
|
Step 2 of Secondary Ossification
|
Cartilage cells start to die- which calcifies the matrix
|
|
|
Step 3 of Secondary Ossification
|
Osteoblasts make Trabeculae of spongy bone
|
|
|
Step 4 of Secondary Ossification
|
Holes of Trabeculae get filled with red bone marrow
|
