An example of a simple synovial joint, e.g. a metacarpophalangeal (finger) joint, is shown above-right. More complicated synovial joints may involve more than two bones, may include sesamoid bones e.g. the patella in the knee joint, may include bursae, and may include accessory ligaments.
The synovial joint, or diarthrosis, is one of the most common joints in mammals. It is also the joint that can be moved the most. This joint gains movement through the contacting point with the surrounding bones, which is common among most of the other joints.There are structural and functional differences that will distinguish the synovial joints from all of the rest of the joints.The main difference between the synovial joints and others is the presence of the capsules around the surface of the synovial joint, along with the presence of the lubricating fluid.The synovial cavity is the space between the bones that contains synovial fluid.his joint gains movement through the contacting point with the surrounding bones, which is common among most of the other joints. There are structural and functional differences that will distinguish the synovial joints from all of the rest of the joints.
