Which term means inflammation of a joint?

• A. Synovitis
• B. Arthritis
• C. Nevus
• D. Lesion

Answer: (B)

The main idea here is identifying the term for inflammation of a joint. Arthritis is the correct term because it describes inflammation of the joints in general, leading to symptoms like pain, swelling, and stiffness. Synovitis is inflammation specifically of the synovial membrane that lines the joint, which can occur within arthritis but is more restricted in scope. A nevus is a skin mole, not related to joints, and a lesion is any abnormal tissue area, not specifically joint inflammation. Hence arthritis is the right term to describe joint inflammation overall.
