Quizplus · Accepted Answer

The mandible is formed via intramembranous ossification, where mesenchymal cells differentiate directly into osteoblasts to form bone without a cartilage precursor. The other options listed are formed via endochondral ossification, where a cartilage model is first formed and then replaced by bone tissue.
