You use them whenever you kick something or serve a tennis ball. Able to reshape itself to avoid any collision between the. Thus plane joints can be functionally classified as a multiaxial joint. These joints allow the bones to slide or rotate against each other, but the range of motion is usually slight and tightly limited by ligaments or surrounding bones. The most common cause of hip disability is osteoarthritis, a chronic disease in which the articular cartilage of the joint wears away, resulting in severe hip pain and stiffness. Which of these joints is correctly matched to the type of synovial joint? It may also help increase the protective power of synovial fluid, and ultimately help mitigate the symptoms of diseases such as rheumatoid arthritis and osteoarthritis, which are characterized by a breakdown of joint cartilage. An example is the first carpometacarpal joint located at the base of the thumb. The articulating surfaces of the bones at a synovial joint are not directly connected to each other by connective tissue or cartilage, which allows the bones to move freely against each other. As the articular cartilage layer wears down, more pressure is placed on the bones. However, ball-and-socket joints allow for large movements, while the motions between bones at a plane joint are small. Ball-and-socket joints are classified functionally as multiaxial joints.
