WebJan 17, 2024 · The perichondrium becomes the periosteum. The periosteum contains a layer of undifferentiated cells (osteoprogenitor cells) that later become osteoblasts. The osteoblasts secrete osteoid against the shaft of the cartilage model (appositional growth). This serves as support for the new bone. WebThe periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow. The perichondrium is very similar to the periosteum. It covers the cartilage on the ends of your bones.
