During endochondral ossification
hyaline cartilage is replaced by bone
hyaline cartilage turns into bone
bone replaced by hyaline cartilage
bone turns into hyaline cartilage
Endochondral ossification occurs
in the irregular bones
mainly in the bones below the skull
only in the skull
in flat bones
The chondrocytes near the center of the shaft enlarge and then die forming cavities
Step 1: Collar bone formation
Step 2: Cavitation
Step 3. Diaphysis Elongation
Step 4: Epiphyseal Ossification
Blood vessels penetrate the diaphysis
Step 1: Collar bone formation
Step 2: Cavitation
Step 3. Diaphysis Elongation
Step 4: Epiphyseal Ossification
Chondrocytes of the perichondrium turn into osteoblasts, the outside of the hyaline cartilage model is replaced by bone
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
Blood vessels start to penetrate to the epiphyses to create secondary ossification centers
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
The medullary cavity is completely formed, osseous tissue along the shaft becomes thicker, and an epiphyseal plate cartilage forms
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
Capillaries and osteoblasts migrate to the epiphysis creating secondary ossification centers
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
The epiphysis gets filled with spongy bone
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
The epiphyseal cartilage starts to form; separation of the epiphysis from the diaphysis
Stage 1: Bone Collar Formation
Stage 2: Cavitation
Stage 3: Diaphysis Elongation
Stage 4: Epiphyseal Ossification
