Calcium hydroxyapatite is the substance most commonly found in bones. Almost 50 % bone is made of this salt and rest is organic material, mostly collagen fibers. Bones are porous so light weight and Calcium salt gives it hardness and organic fibers gives it flexibility like cement and steel rods in cement concrete.
Osteocytes are the most abundant bone cell type comprising about 95% of all bone cells. Although relatively inert, they are capable of molecular modification and synthesis.
The red bone marrow makes red blood cells. The yellow bone marrow makes chemical energy.
Red bone marrow is found in spongy bone located mostly in the ends of the long bones.Red marrow is found mainly in the flat bones such as hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the proximal ends of the long bones femur and humerus.
The important organic components of bone include collagen, which provides strength and flexibility, and non-collagenous proteins, which regulate mineralization and bone formation. These organic components work together with inorganic minerals like calcium and phosphate to give bone its structure and functionality.
A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is like honeycomb, lighter and slightly flexible. In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for the blood.
Collagen is the most abundant protein found in bone. It provides strength and structure to the bone tissue.
Bone marrow is the gel-like substance that produces blood cells. It is found within the bone.
Bone marrow is the substance that is found at the core of bones, and is either made of fat or red blood cells depending on the type of bone in question. For spongy bone, the marrow is made of red blood cells.
There actually is no lime green bone fragment after cremation. It is actually a grey green substance known as bone fragments.
Osteocytes are the most abundant bone cell type comprising about 95% of all bone cells. Although relatively inert, they are capable of molecular modification and synthesis.
