Endochondral Ossification-PART II epiphysis

step 1

cartilage cells undergo apoptosis

step 2

blood vessels bring in osteoprogenitor cells and osteoblasts into the secondary ossification center

step 3

osteoblasts produce osteoid

step 4

osteoblasts stimulate calcification causing the formation of osteocytes in lacunae

step 5

women bone is formed, then lamellar, then spongy bone

step 6

some spongy bone becomes compact bone
