Osteoporosis

The skeleton of an adult human consists of 260 bones, and each one is complex in the biological and mechanical sense education. Each bone consists of the bone marrow, articular cartilage, blood vessels and nerves. The outer surface of bone covered with periosteum, the so-called thin film, which is responsible for the growth, nutrition and recovery of bones in case of breakage. Skeletal system does in the body are three important features: mechanical, protective, and metabolic. The first is that the bones with cartilage and muscles form the musculoskeletal system of the body. At the same time, the skeletal system serves as a skeleton protecting our vital organs from external influences. Finally, function involves the participation of bone in general metabolism and maintain a constant internal environment.

The basis vital bone are two interrelated processes that take place at different speeds throughout a person's life: the process of old bone and the process of creating a new one. In children and adolescence, the bones are actively building up when the bone formation prevails over destruction. To approximately 25-30 years reached 'peak bone mass', occurs in a relatively short period of balance between processes of destruction and creation. Then, after 40 years, begins a process of gradual bone loss. Normally, this process is natural and quite slow. The problems begin, if, due to certain reasons, he accelerated. Then and there Osteoporosis is a disease of the skeleton, which is characterized by a decrease in bone density and the risk of fractures even with a small impact.
