Step-by-step explanation:
Rheumatoid arthritis (RA) is an inflammatory disorder that primarily affects the synovial joints of the hands, feet, and cervical spine. The affected joints become swollen, stiff, and painful. RA is an autoimmune disease where the body's immune system attacks its own healthy tissue, leading to cartilage breakdown, joint inflammation, and pain. It is more common in women, usually occurs between the ages of 40-50, and there is no known cure. Treatment aims to manage symptoms with medications, exercise, and sometimes surgery.
