Almost every bone in your body is made of the same materials:
- The outer surface of bone is called the periosteum (say: pare-ee-os-tee-um). It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone.
- The next layer is made up of compact bone. This part is smooth and very hard. It's the part you see when you look at a skeleton.
- Within the compact bone are many layers of cancellous(say: kan-sell-us) bone, which looks a bit like a sponge. Cancellous bone is not quite as hard as compact bone, but it is still very strong.
- In many bones, the cancellous bone protects the innermost part of the bone, the bone marrow (say: mair-oh). Bone marrow is sort of like a thick jelly, and its job is to make blood
