Rheumatoid arthritis
Rheumatoid arthritis

Rheumatoid arthritis is an autoimmune disease in which the body's immune system attacks itself. The pattern of joints affected is usually symmetrical, involves the hands and other joints and is worse in the morning. Rheumatoid arthritis is also a systemic disease, involving other body organs, whereas osteoarthritis is limited to the joints. Over time, both forms of arthritis can be crippling.

Rheumatoid arthritis is a systemic autoimmune disease which initially attacks the synovium, a connective tissue membrane that lines the cavity between joints and secretes a lubricating fluid.

The affect of rheumatoid arthritis can progress to the degree that it is crippling. Deformities distinctive to late-stage rheumatoid arthritis such as ulnar deviation of the bones of the hands, or swan-neck deviation of the fingers occur because muscles and tendons on one side of the joint may overpower those on the other side, pulling the bones out of alignment.

The synovial membrane is the inner membrane of tissue that lines a joint. The synovial membrane secretes synovial fluid which serves to lubricate the joint.

Rheumatoid arthritis is another form of arthritis. The body's own immune system attacks a joint's synovial membrane, which secretes fluid and lines the joint. The synovium becomes inflamed, produces excess fluid, and the cartilage becomes rough and pitted.
