Rheumatoid arthritis (ra) is a long-term autoimmune disorder that primarily affects joints it typically results in warm, swollen, and painful joints pain and stiffness often worsen following rest most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body the disease may also affect other parts of the body. Rheumatoid arthritis pathology rheumatoid arthritis pathology consists of the changes that take place in the tissues that are involved in the disease these changes are mainly seen in the synovium which is the tissue that is covering the inner lining of the joints.
Rheumatoid arthritis (ra) is the most common inflammatory arthritis and affects about one percent of the population  it results from a complex interaction between genes and environment, leading to a breakdown of immune tolerance and synovial inflammation in a characteristic symmetric pattern. Rheumatoid arthritis is best characterized as an immune mediated inflammatory disease (imid) within a framework that recognizes both immunological activation and inflammatory pathways, we can begin to evaluate the multiple components of disease initiation and propagation. Chronic systemic inflammatory disorder affecting synovial lining of joints, bursae and tendon sheaths also skin, blood vessels, heart, lungs, muscles (davidson college: rheumatoid arthritis) produces nonsuppurative proliferative synovitis, may progress to destruction of articular cartilage and joint ankylosis.

Rheumatoid arthritis is a chronic inflammatory disease that affects connective tissues throughout the body, particularly the synovial membranes that line the peripheral joints rheumatoid arthritis is one of the most common autoimmune diseases. Femoral head, left, hip arthroplasty: - chronic synovitis with synovial hyperplasia and loss of cartilage - bone without apparent pathology - see comment comment: the findings are compatible with rheumatoid arthritis hand synovium, left hand, excision: - synovial hyperplasia - chronic and focal acute synovitis - fibrinous exudate. Juvenile idiopathic arthritis (jia), also known as juvenile rheumatoid arthritis (jra), is a heterogeneous group of diseases that differs markedly from adult ra.
Rheumatoid arthritis (ra) is a chronic systemic inflammatory disease of unknown cause the hallmark feature of this condition is persistent symmetric polyarthritis (synovitis) that affects the hands and feet, though any joint lined by a synovial membrane may be involved.
