Final answer:
Endochondral ossification forms the model for bone development using hyaline cartilage. A framework of cartilage is laid down during fetal development and gradually replaced by bone. The mesenchyme between the developing bones becomes the fibrous connective tissue that unites the bones at their joints.
Step-by-step explanation:
Endochondral ossification forms the model for bone development. During this process, bones develop from hyaline cartilage. A framework of cartilage is laid down during fetal development, which determines where bones will form. Over time, this cartilage model is gradually replaced by bone. The mesenchyme between the developing bones becomes the fibrous connective tissue that unites the bones at their joints.
