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.
Disorders of the bone may involve the osseous tissue. Physical therapy can help some people rebuild strength and bone density lost to disorders such as osteoporosis. Osseous tissue is the primary constituent of bone, creating the mineral matrix that makes bones hard, strong, and lightweight.
Ossification (or osteogenesis) in bone remodeling is the process of laying down new bone material by cells called osteoblasts.It is synonymous with bone tissue formation.There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue (mesenchyme), while endochondral ossification involves cartilage as a precursor.alcification is synonymous with the formation of calcium-based salts and crystals within cells and tissue. It is a process that occurs during ossification, but not vice versa. The exact mechanisms by which bone development is triggered remains unclear, but it involves growth factors and cytokines in some way.
