Bending of the tip of the finger exhibits flexion. In simple terms, synovial structures facilitate the movement between independent structures by providing a hydraulic cushion of viscous fluid that limits the effects of friction to help dissipate. It protects and cushions the articular cartilage during movement. c)only those that contain a joint cavity will eventually allow fusion of the articulating bones. Here, synovial fluid is a viscous, non-Newtonian fluid, which occurs in the cavities of synovial joints. An unusual side effect occurs when a joint is placed under steady pressure: the carbon dioxide forms a bubble within the fluid that pops noisily.

The purpose of this fluid is to lubricate the cartilage of the bone joint and provide nourishment through diffusion. Together, all these anatomic elements form the joint, which is enclosed in the articular capsule. Definition (MSH) The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. Thus, the fluid is usually classified as being non-inflammatory (degenerative joint disease or trauma) or inflammatory, based on the nucleated cell count, total protein, viscosity, types of cells and appearance of cells in the fluid (see algorithm). Surface of the membrane surrounding the joint consists of numerous microvilli with a layer, 1-3 cells deep, of synovial cells called synoviocytes Synoviocytes It contains hydrochloric acid. 39) 40) A ball - and - socket joint is a multiaxial joint.
