Perichondrium is invaded by blood vessels. 4. In the primary ossification center, osteoblasts replace calcified cartilage with early spongy bone. 5.

Answer 1

Endochondral ossification

Step-by-step explanation:

• The Correct order is 3,5,2,1,4
• Endochondral ossification includes the supplanting of hyaline ligament with hard tissue.
• A large portion of the bones of the skeleton are shaped right now. These bones are called endochondral bones.
• The future bones are first shaped as hyaline ligament models.
• Endochondral solidification is additionally a basic procedure during the simple arrangement of long bones, the development of the length of long bones, and the characteristic mending of bone fractures.
