Bone Growth
Growth in Thickness | Bone Tissue |
---|---|
appositional growth | growth in thickness or diameter |
1. periosteal cells | differentiate int osteoblasts and secrete collagen fibers/organic molecules to form the matrix |
2. periosteum become endosteum | ridges fuse |
3. new concentric lamellae | are formed |
4. new circumferential lamellae | formed by osteoblasts under the peritsteum |
