Human bones are made up of many layers and components. Each one has a specific function. We have seen the bones from outside, but what is filled inside the bones, which makes them so strong? Is this structure the cause of pain? A post has been shared on social media from @Rainmaker1973 account, in which it has been explained in detail.
According to the post, the outermost layer of the bone is called periosteum. This layer is a hard, fibrous membrane, which covers the entire bone. This membrane is not present only at those places where it connects to other bones. It contains blood vessels, nerves and lymph vessels that provide nutrients to the bone tissue. Beneath the periosteum is compact bone. This is the hard, dense outer layer of the bone. This layer provides strength and protection to the bone. Compact bone is composed of a matrix of calcium and collagen fibers. These are intertwined in the Haversian system. Small and cylindrical. These also contain blood vessels and nerves.

spongy or soft bones inside the outer layer
Inside this solid outer layer of bone there are spongy or soft bones. You can also see it in this picture going viral. By joining thin pieces it forms a mesh-like network, which is called trabeculae. These are woven in such a way that they can bear maximum weight. Look more powerful. Spongy bone is found primarily at the ends of long bones, such as the femur (thigh bone) and humerus (upper arm bone), and in the spine.
bone marrow in the very center of the bone
Bone marrow is located at the very center of the bone. It is a soft, spongy tissue, which produces blood cells. This stores fat. Bone marrow is also of two types. The first is the red marrow, which produces red blood cells, white blood cells and platelets. The second is the yellow marrow, which mainly stores fat. According to experts, whenever there is any strain in them, you feel pain. If blood circulation continues to occur properly then there is no problem.
