Exam 6: Skeletal System: Bones and Bone Tissue

Arrange the following events in endochondral ossification in proper sequence: (1) Cartilage matrix is calcified and chondrocytes die. (2) Chondrocytes hypertrophy. (3) Cartilage model is formed. (4) Osteoblasts deposit bone on the surface of the calcified cartilage called the primary ossification center. (5) Blood vessels from the periosteum invade calcified cartilage bringing in osteoblasts and osteoclasts.
