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.
Mineralized osseous tissue or bone tissue, is of two types â cortical and cancellous and gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.one is an active tissue composed of different cells. Osteoblasts are involved in the creation and mineralisation of bone; osteocytes and osteoclasts are involved in the reabsorption of bone tissue.
