Q

Development of
Bones

A
  • Cartilage – mostly in infants
  • strong flexible tissue.
  • Over time it is replaced by solid bone in growth development
  • Not all cartilage is replaced in adults
  • Coastal Cartilage - hyaline cartilage that serve to prolong the ribs forward
  • Extension lang sa ribs
