Question

what is meant by ossification

Answer 1

✔️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.
