Question

Synovial fluid is secreted by

• A. Blood
• B. Cartilage
• C. Bone
• D. Synovial membrane

Answer 1

The correct option is D Synovial membrane

Membranes are thin pliable layers of epithelial and/or connective tissue. They line body cavities, cover surfaces, connect, or separate regions, structures and organs of the body.

The three kinds of membranes are mucous, serous and synovial.

Synovial membrane, unlike to other membranes does not contain epithelium. Therefore, it is not the epithelial membrane. It lines the cavities of the freely movable joints. Like serous membrane, it lines structures, that do not open to the exterior. Synovial membranes secrete the synovial fluid that lubricates articular cartilage at the ends of bones as they move at joints.
