what ossification has initial bone formation in embryo begins within cartilage

what ossification is replaced by bone

what ossification uses cartilage as small model and bones grow in diameter and length

what ossification and step is in shaft, where chondrocytes enlarge and matrix ossifies

what ossification and step has blood vessels grow around cartilage edge and osteoblasts form to create a superficial layer of bone

what ossification and step has blood vessels penetrate central region allowing entering fibroblasts to change into osteoblasts. primary ossification center

what ossification and step has medullary cavity created as cartilage is replaced by osseous tissue

what ossification and step secondary ossification center form as capillaries and osteoblasts migrate into epiphyses

what ossification and step has epiphyses fill with spongy bone, only articular cartilage and epiphyseal cartilage remain

what ossification and step does bone grow in length at epiphyseal cartilage

what ossification begins as mesenchymal cells that differentiate into osteoblasts within embryonic or fibrous connective tissue

what ossification normally occurs in deeper layer of dermis (dermal bones)

what ossification occurs in roofing bones of skull, lower jaw, collarbone, and sesamoid bones

what ossification and step has mesenchymal cells secrete osteoid matrix and differentiate into osteoblasts

what ossification and step has osteoid matrix that becomes mineralized and forms ossification center

what ossification and step has bones grow out in small struts (spinules)

what ossification and step has osteoblasts become trapped and mature into osteoclasts

what ossification and step has blood vessels enter and become trapped in developing bone

what ossification has spongy bone formed initially and remodeling around blood vessels forms osteons of compact bone

what ossification has periosteum forms, lined with osteoblasts and begins at approximately 8th week of embryonic development
