How does the 'Zone of Ossification' (or Resorption) differ from the 'Zone of Calcification'?
Show answer and explanation
Correct answer: It features osteoblasts depositing bone on calcified cartilage remnants.
The zone of ossification is the final stage at the epiphyseal plate. Here, blood vessels and osteoblasts invade the spaces left by dead chondrocytes, and osteoblasts lay down a 'mixed spicule' of bone on top of the calcified cartilage remnants.
