Bone Classification Based On: Development:
Immature and Mature (based on which comes first)
Bone Classification Based On: Organization
Lamellar (sheets) or Osteonal (circular)
Bone Classification Based On: Configuration (Shape)
Spongy and Compact
Immature Bone: Spongy bone
Spongy bone: more interosseous space (area) than osseous (bone ECM)
trabecular bone, cancellous bone, woven bone, primary bone
Spongy -comprising mostly immature bone; synonyms include
osteonal bone, lamellar bone, secondary bone, cortical bone
Compact -comprising mostly mature bone; synonyms include:
Osteon/Haversian
Osteon/Haversian system (comprises most of compact bone)
Bone Preparation: Decalcified Calcium
Calcium salts are removed through treatment of the tissue
Then bone is cut and stained normally
Trichromeis usually used-bone will stain blue, other tissues pink to red.
Ground
Bone is sawed into thin sections and then ground down until it can be observed using light microscopy.
No Staining.
