Which structure produces synovial fluid to lubricate the joint?

• A. Tendons
• B. Synovial fluid
• C. Hyaline cartilage
• D. Ligaments

Answer: (B)

Synovial fluid lubricates the joint and is produced by the synovial membrane that lines the joint capsule. The membrane contains cells (synoviocytes) that secrete fluid rich in hyaluronic acid, forming a slippery film that reduces friction between the articular surfaces and helps nourish cartilage. The other options—tendons, hyaline cartilage, and ligaments—do not produce this lubricating fluid; they have roles in movement and stability. In this set, the term that relates to the lubrication inside the joint is synovial fluid, which is produced to perform that lubrication (though the actual source is the synovial membrane).
