Long bones are developed by endochondral ossification, which requires a cartilage precursor.
There are two ways bones are formed, intramembranous ossification, and endochondral ossification. Intramembranous ossification is how the flat bones are formed, while the long bones are formed with endochondral ossification.
Intramembranous ossification Endochondral ossification Appositional growth
No, the primary ossification center of a long bone is found at the center of the diaphysis. Hope that helps.
Endochondral ossification.
diaphysis
Endochondral Ossification meaning "formed in cartilage.
Monkey Usually live as long as humans do
Ossification means bone growth or formation. I will be disscussing breifly normal or physiological ossification because there is pathological ossification.There are two types of ossification in the human body: endochondral and intramembranous. Most of the bones in the human skeleton , especially the long and short bones, develop via endochondrial ossification, but some including the clavicle and most of the bones of the skull( flat bones) are formed by the intramembranous type. Intramembranous ossification , the source of most of the flat bones, is so called because it takes place within condensations of mesenchymal tissue and not by replacement of pre-existing piece of hyaline cartilage as the case in endochondral ossification. The frontal and parietal bones of the skull, as well as parts of the temporal and occipital bones and the mandible and maxilla, are formed by intra membranous ossification. This process also contributes to the growth of short bones and the thickening (not the lengthening) of long bones.

They usually are fine as long as you don't threaten them in anyway
