Compact bone is very densely compacted bone, this makes up the main shaft of the bones, this dense compaction is what gives them strength. Bone has different structures, these include the diaphysis which is the main shaft of the bone, the epiphysis which is the extremities of the bone, the articular cartilage which forms a joint and is a thin layer of cartilage which covers the epiphysis of the bone. The periosteum is the tough fibrous coating that covers that contains nerves, blood vessels and lymph vessels that go into the bone, they also act as a point of attachment for ligaments and tendons.
