Reasons for the Population Decline. There is no question but that the populations of most European countries will decline in the next generation, and in the cases of Germany and Russia, the decline will be dramatic. In fact, the entire global population explosion is ending.
Osseous tissue is a type of connective tissue found in bone. It is the primary constituent of bone, creating the mineral matrix that makes bones hard, strong, and lightweight. Along with osseous tissue, the bones also include marrow, blood vessels, nerves, and epithelium, which covers the surface of the bone.
Osteoblasts are bone-forming cells, have an extensive endoplasmic reticulum and numerous ribosomes. Ossification is the formation of bone by osteoblasts. Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed.
