Detailed explanation-1: -Endochondral ossification is the process by which growing cartilage is systematically replaced by bone to form the growing skeleton. This process occurs at three main sites: the physis, the epiphysis, and the cuboidal bones of the carpus and tarsus.
Detailed explanation-2: -Endochondral ossification occurs at two distinct sites in the vertebrate long bone – the primary (diaphyseal) and the secondary (epiphyseal) sites of ossification. Bone development initiates at the primary site. The secondary (epiphyseal) site is under independent control and is ossified later (Figure 1b).
Detailed explanation-3: -Facial bones that ossify through endochondral process, include the temporal, sphenoid, zygomatic, and basioccipital bones and are part of the cranial base.
Detailed explanation-4: -Intramembranous ossification directly converts the mesenchymal tissue to bone and forms the flat bones of the skull, clavicle, and most of the cranial bones.
