The outer lining of the connective tissue that surrounds the diaphysis of a long bone and contains the blood vessels that supply the bone periosteum
<h3>Bone Structure</h3>
The periosteum (peri = "around" or "surrounding") is a fibrous membrane that covers the exterior of bones. Compact bone is nourished by the blood, nerve, and lymphatic veins found in the periosteum. At the periosteum, ligaments and tendons also connect to bones.
<h3>
What is the diaphysis' structure?</h3>
The diaphysis's walls are made of firm, the compact bone that is dense and compact. A typical long bone demonstrates the basic anatomical features of bone. The epiphysis (plural: epiphyses), which is filled with spongy bone, is the broader portion at each end of the bone. The gaps in the spongy bone are filled with red marrow.
<h3>What is the purpose of the bone's outer layer?</h3>
The outer layer contains nerve fibers that produce pain when the tissue is injured and is primarily made of collagen. Additionally, it has a large number of blood arteries, some of which have branches that enter the bone and nourish the osteocytes or bone cells.
