The synovial membrane, also known as synovium, is a specialized connective tissue that lines the cavities of synovial joints, such as the knees, elbows, and hips. Its primary function is to produce synovial fluid, a viscous fluid that lubricates the joint, reduces friction between the articular cartilages of the bones, and nourishes the cartilage.
