ossification

Examples of ossification in the following topics:

• Bone Development

  • Intramembranous ossification stems from fibrous membranes in flat bones, while endochondral ossification stems from long bone cartilage.
  • The development of bone from fibrous membranes is called intramembranous ossification; development from hyaline cartilage is called endochondral ossification.
  • Intramembranous ossification is the process of bone development from fibrous membranes.
  • They then differentiate into osteoblasts at the ossification center.
  • Endochondral ossification is the process of bone development from hyaline cartilage.

• Growth of Bone

  • It is a layer of hyaline cartilage where ossification occurs in immature bones.
  • The newly-deposited bone tissue at the top of the zone of ossification is called the primary spongiosa.
  • The older bone at the bottom of the zone of ossification is called the secondary spongiosa.
  • At the same time, osteoblasts via intramembranous ossification, produce new bone tissue beneath the periosteum.
  • The bottom-most row is the zone of ossification which is part of the metaphysis.
