Expert Answer:

  • The process of formation of bones is called ossification. It is the gradual transition from a fibrous or a cartilaginous template to a bone. The formation of bone is actually the conversion of other types of connective tissues into bone.
  • Ossification occurs at certain sites known as centers of ossification.
  • The process is initiated by the activity of osteoblasts. Osteoblasts are bone forming cells and secrete collagen and other substances that form the ground substance of bone.
  • The centers of ossification may be primary or secondary.
  • The primary centers of ossification appear before birth and are the first to start the process of ossification.
  • The secondary centers of ossification mostly appear after birth. The secondary centers are sites where process of ossification starts after it has started in primary centers.
