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 |
