  3. Only in the articular cartilage
  4. In the endosteum and the inner periosteum
Show answer and explanation

Correct answer: In the endosteum and the inner periosteum

Osteoblasts are surface-dwelling cells. They line the endosteal surfaces (including Haversian canals and trabeculae) and the osteogenic (inner) layer of the periosteum, where they can add new bone matrix.
