Bone from children with OI Type I often appeared normal in microstructure and amount, but in some there was a dearth of bone and microscopic structure of bone abundance of osteocytes. Compared with age-matched controls, cortical and trabecular bone from children with OI Types III and IV were markedly sparse and very cellular, and primary osteonal systems continued to be formed later than expected.

A distinguishing feature of the bone from OI Type V patients was the failure of patches of bone to mineralize, especially adjoining a reversal line.

Bone Microscopic structure of bone Bones form by replacing connective tissues in the fetus. Some form within sheet-like layers of connective tissue intramembranous boneswhile others replace masses of cartilage endochondral bones.

Osteoblasts deposit a bony matrix around themselves in all directions, forming spongy bone. Once the deposited bony matrix completely surrounds the osteoblasts, they are then called osteocytes.

Microscopic structure of bone of the membranous tissue that lie outside the developing bone give rise to the periosteum. The diaphysis is the shaft of the bone and has walls of cortical bone and an underlying network of trabecular bone.

The epiphyseal growth plate lies at the interface between the shaft and the epiphysis and is the region in which cartilage proliferates to cause the elongation of the bone.

The metaphysis is the area in which the microscopic structure of bone of the bone joins the epiphyseal growth plate. Different areas of the bone are covered by different tissue: The epiphyses are lined by a layer of articular cartilage, a specialized form of hyaline cartilage, which serves as protection against friction in the joints.

The outside of the diaphysis is lined by periosteum, a fibrous external layer onto which muscles, ligaments, and tendons attach. The inside of the diaphysis, at the border between the cortical and cancellous bone and lining the trabeculae, is lined by endosteum.

Microscopic Bone Structure Compact bone is organized as parallel columns, known as Haversian systems, which run lengthwise down the axis of long bones. These columns are microscopic structure of bone of lamellae, concentric rings of bone, surrounding a central channel, or Haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone.

The parallel Haversian canals are connected to one another by the perpendicular Volkmann's canals. How to grow a bone: Most of the bones of the skeleton fall into this category.

They first develop as hyaline cartilage models shaped like the future bones and are then replaced with bone. Cartilage is broken down in the diaphysis and progressively replaced with bone while the periosteum develops on the outside.

Disintegrating cartilage is invaded by blood vessels microscopic structure of bone osteoblasts that first form spongy bone at the primary ossification center in the diaphysis.
