Explain how primary bone differs from secondary bone
What will be an ideal response?
Primary bone is the first, immature bone formed by both intramembranous and endochondral ossification. Primary bone consists of irregularly arranged collagen bundles, abundant osteocytes, and little inorganic matrix. In most cases, primary bone is resorbed by osteoclasts and replaced by mature secondary bone. Secondary bone has fully formed lamellae with regularly arranged collagen bundles that are parallel to one another, which makes it much stronger than primary bone. In addition, secondary bone contains a higher percentage of inorganic matrix, which contributes to its strength.
