The fоllоwing аre the steps in the prоcess of endochondrаl ossificаtion:7. At puberty, epiphyseal cartilage production slows and the rate of osteoblast activity accelerates. Epiphyseal cartilage ultimately disappears. 3. Cartilage enlarges, chondrocytes near the center of shaft increase greatly in size. Matrix is reduced to a series of small struts that soon begin to calcify. Enlarged chondrocytes die, disintegrate, and leave cavities in the cartilage. 1. Blood vessels grow around the edges of the cartilage, and the cells of the perichondrium convert to osteoblasts. 5. Remodeling occurs as growth continues creating a medullary cavity. 6.The epiphyses becomes filled with spongy bone. Ephyseal plate now separates the epiphysis from the diaphysis. 4. Blood vessels penetrate the cartilage and invade the central region. 2. Capillaries and osteoblasts migrate into the epiphyses creating secondary ossification centers. What is the correct order for these events from start to finish?
