Detailed explanation-1: -This process involves the replacement of hyaline cartilage with bone. It begins when mesoderm-derived mesenchymal cells differentiate into chondrocytes. Chondrocytes proliferate rapidly and secrete an extracellular matrix to form the cartilage model for bone.
Detailed explanation-2: -Endochondral ossification At such sites the cartilage begins to undergo hypertrophy and calcification, allowing the penetration of blood vessels which bring with them the osteoblast and bone marrow precursors. This is therefore an example of endochondral ossification.
Detailed explanation-3: -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. Endochondral ossification takes much longer than intramembranous ossification.
