B. Deposition of cartilage
C. Ossification of the template
C then B then A

During bone formation and growth, what is the order of ossification?
Neither structure is ever ossified.
Ossification occurs at the same time.
The epiphyses then the diaphysis.
The diaphysis then the epiphysis.
When would osteoblasts be activated?
When the bone is exposed to regular stress.
When there is a lack of phosphorus in the body.
When the osteoclasts activate them.

Put the Endochondral ossification process in order:
A. Chondrocytes produce cartilage to grow templates.
B. Marrow cavities begin to form inside - diaphysis will ossify - THEN marrow forms
C. Osteoblasts deposit bone around the hyaline cartilage template
D. Epiphysis will ossify (end of growth/puberty)
E. Hyaline cartilage template is formed by Chondrocytes.
