Outline: BONE FORMATION = (osteogenesis) begins during prenatal development and continues through adulthood.

  • A bodies bone is softer because it has yet to ossify, the process of synthesizing cartilage into bone.
  • 2 Ways to have osteogenesis occur. Intra membrous ossification this form mostly uses the cell called an osteoclast
  • Specialized cells in bone tissues that deposit calcium into the bone matrix (collagen).
  • Osteoclast - are the specialized cell that dissolve calcium previously stored away in bone and carry it to tissues whenever needed.
  • One third of all the bones components is collagen
  • Collagen = A flexible gelatin like matrix.

Intramembranous Ossification:

  • As seen under a microscope, membranous bones first appear as flat, membrane-like layers of early connective tissues.
  • Osteoblast are formed and remove calcium from the blood system and then apply it to the matrix.
  • Osteoblast cover a spongy bone layer in a harder ossified layer that then turns the osteoblast into osteoclast.
  • The old osteoblast come back up and add another spongy layer and continue to add harder bone layers.
  • This process is slow and time consuming.
