Question

question 1
ossification that involves replacing cartilage with bone is:
a intramembranous
b endochondral
c appositional
d interstitial
e osteomalacia

Explanation:

• Intramembranous ossification forms bone directly from mesenchymal tissue, not replacing cartilage.
• Endochondral ossification specifically replaces cartilage with bone.
• Appositional growth is about increasing bone thickness, not the initial ossification process replacing cartilage.
• Interstitial growth is related to cartilage growth within the tissue itself, not its replacement by bone.
• Osteomalacia is a disorder of bone softening, not an ossification process.

Answer:

B. endochondral
