ENDOCHONDRAL OSSIFICATION – 5
The Zone of hypertrophic cartilage of the epiphyseal disc, responsible for the growth in length of the vertebra, is highlighted in light green.
Cartilage matrix walls remained after the hypertrophic chondrocytes placed at the center of the bone model died. They are highlighted in dark green. Osteoblasts are settling on these partitions and will secrete bone extracellular matrix, and become osteocytes.
Bone highlighted in red was produced by intramembranous ossification taking place at the bone collar.
The area occupied by bone marrow is indicated.
