What does Rheumatoid Arthritis affect?

• A. The muscle tissues
• B. The lining of the joints
• C. The blood vessels
• D. The skin

Answer: (B)

Rheumatoid Arthritis primarily affects the lining of the joints, also known as the synovium. This is an autoimmune disorder in which the body’s immune system mistakenly attacks the synovial tissue, leading to inflammation, swelling, and pain in the affected joints. Over time, this chronic inflammation can result in joint damage and deformity.

By targeting the synovial lining specifically, Rheumatoid Arthritis disrupts the body's normal functioning, leading to the symptoms that patients experience, such as stiffness, especially in the morning, and a reduced range of motion. Understanding this key aspect of the disease is crucial for managing and treating the condition effectively. The connection to joint health is central to recognizing how Rheumatoid Arthritis impacts individuals and the importance of timely intervention to mitigate long-term consequences.
