Rheumatoid arthritis (RA)

Rheumatoid arthritis (RA)

Rheumatoid arthritis (RA) is a chronic inflammation of unknown cause, affects the joints in different parts of the body parallel to the left and right sides and affect most of the time on the small joints of the hand. This inflammation is caused the destruction of the synovial membrane that connects the bones and joints, and is one of the most important types of arthritis cause of disability. Rheumatoid arthritis is a chronic disease of the autoimmune disease that causes inflammation and abnormalities in the joints. The other problems occur in all parts of the body may include inflammation of the blood vessels, development and swellings called nodules articulated in different parts of the body, lung disease, blood disorders, weakened bones or the so-called osteoporosis.DescriptionThe structural system consists of different types of tissues strong, fibrous tissue called connective tissue. The bone and cartilage, ligaments, tendons forms of connective tissue that have different compositions and different properties.Joints are structures that combine two or more of the bones together. Some joints such as synovial joints allow movement between the bones collected. Simplest diarthrosis combines two bones, separated by a small gap called the joint cavity. And covers the ends of bones layer of articular cartilage. And surrounds the bones of the joint and the joint cavity strong tissue called articular capsule. The portfolio consists arthropod of two elements, fibrous membrane abroad and synovial membrane inside. The membrane contains a strong fibrous fascias of tissue called ligaments, which is responsible for providing support and protection of the joints. Synovial membrane contains special cells and many of the small blood vessels or capillaries. This membrane produces the amount of synovial fluid that fills the joint cavity, Azelgah, and helps the bones of the joint movement smoothly into the joint.In arthritis Romatioada, synovium becomes inflamed strongly. As is usually thin and delicate, the synovium becomes Semekhaoukasaa, with many folds on the surface. And invade the membrane of white blood cells, which produce a variety of destructive chemicals. And can attack the cartilage along the articular surfaces of the bones, and destruction, and could begin the bone, and joint capsule, and ligaments in corrosion. These processes interfere severely in the movement of the joint.Rheumatoid arthritis is found throughout the world and affects men and women of all races. And women are more likely three times that of men. It seems that the disease appears in certain families, although some environmental factors may also affect the progression of this disease.
