Endochondral ossification

Three metacarpal bones of the fetal hand have been cut in cross section at different distances from the epiphyseal plate, showing the gradual resorption of bony spicules. On the left, numerous spicules are present, indicating a region close to the epiphyseal plate. On the right, few spicules remain, demonstrating an area closer to the mid-diaphysis. 10x
