Which term denotes the fluid in joints?

• A. Aqueous
• B. Synovial
• C. Interstitial
• D. Lymphatic

Answer: (B)

In joints, the fluid that lubricates and nourishes the cartilage is synovial fluid. It is produced by the synovial membrane lining the joint capsule and works to reduce friction during movement, supply nutrients to the avascular articular cartilage, and help absorb shocks. Aqueous refers to fluids like the aqueous humor in the eye or general aqueous solutions, not the joint cavity. Interstitial fluid is the fluid between cells in tissues, not the joint space. Lymphatic fluid (lymph) circulates in the lymphatic system, separate from the joint fluid. So the term denoting the fluid in joints is synovial.
