|---|---|
| Bone | 2nd hardest natural body substance, composed of cells (osteoblasts and osteocytes) embedded in a matrix |
| Ossification | hardening of the matrix |
| Bone Functions | -support, protection, leverage, storage, blood cell formation (hematopoiesis) |
| Cancellous Bone | light and spongy bone, tiny "spicules of bone appear randomly arranged. |
