The Periosteum.
Bones are covered with the periosteum.
The type of bone that covers the shaft of long bones is called compact bone.
The priosteum
The priosteum
the periosteum covers the bone everywhere there is not articular cartilage
Actually it's cartilages and the synovial fluid which makes the joint movements smooth.....
Hyaline cartilage covers the ends of bones in many joints. It provides a slippery surface to reduce friction during bone movement.
Each bone has a tough, smooth, shiny substance that covers the end. This substance that covers the ends of bones is called cartilage.
I believe it's immature bone because it has the mesenchyme cells, osteoprogenitor cells and osteoblasts. While mature bone has the osteocytes.
metaphyses are the regions in a mature bone where the diaphysis joins the epiphyses. in a growing bone each metaphysis includes a epiphyseal plate
T-Cell mature in Thymus B-Cell mature in Bone Marrow
