WebThe following events apply to the endochondral ossification process as it occurs in the primary ossification center. Put these events in their proper order by assigning each a number (1–6).(a) Cartilage in the diaphysis calcifies, and chondrocytes die anddisintegrate, leaving cavities.(b) A collar of bone is laid down around the hyaline cartilage modeljust … WebThree modes of ossification take place during DO. Although endochondral ossification occurs during early stages of DO, intramembranous bone formation is the predominant mechanism of ossification, particularly in later stages. A third form of ossification, called ‘transchondroid bone formation’, has been suggested to occur.
WebEndochondral Ossification. In endochondral ossification, bone develops by replacing hyaline cartilage. Cartilage does not become bone. Instead, cartilage serves as a template to be completely replaced by new bone. In a long bone, for example, at about 6 to 8 weeks after conception, some of the mesenchymal cells differentiate into chondrocytes (cartilage … Webcanal.
