From there, the blood vessels enter another group of channels called Haversian canals, which run along the length of the bone. WebThe periosteum contains a layer of undifferentiated cells (osteoprogenitor cells) which later become osteoblasts. Formation of bone collar The osteoblasts secrete osteoid against the shaft of the cartilage model (Appositional Growth). This serves as support for the new bone.
