Organization of Cartilage within the Epiphyseal Plates of Growing Long Bones :)

Organization of Cartilage within the Epiphyseal Plates of Growing Long Bones

1. Resting Zone (Closest layer to the epiphysis)

   • Proliferation Zone
     • Hypertrophic Zone
       • Calcification Zone
         • Ossification Zone
           • Trabecular Bone produced
             • Osteoblasts and Osteoclasts working together
         • Trabecular-like cartilage
       • Older Chondrocytes Enlarge
         • Signal Matrix to calcify
     • Reproducing Cartilage
       • Lengthening metaphysis
   • Inactive Cartilage

2. Epiphyseal Plates: Secondary Ossification Centers

   • Bone matrix from primary and secondary ossification centers= Bone maturity achieved
