ossification

Question 23

Explain the length of bone growth

Answer 23

bone develops as cartilage and is added to the epiphyseal disks

Explain the growth of bones

Answer 24

in thickness is due to depositing of compact bone on outside and eroding on the inside (this erosion creates the medullary cavity)
