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.
Connective tissue is classified as connective tissue proper, osseous tissue, and cartilaginous tissue, depending on the composition of the cells and the type, properties, and orientation of intercellular structures. Connective tissue proper may be irregularly or regularly arranged. Irregularly arranged connective tissue with fibers that are irregularly interwoven may be loose (areolar) or dense. An example of loose connective tissue is subcutaneous tissue, as well as connective tissue, which fills the spaces between organs and accompanies blood vessels. An example of dense connective tissue is the corium, or connective-tissue base of the skin.
