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.
There are many different classes of synovial joints in the body, including gliding, hinge, saddle, and ball and socket joints. 1  Gliding joints, such as the ones between the carpals of the wrist, are found where bones meet as flat surfaces and allow for the bones to glide past one another in any direction.here are many different classes of synovial joints in the body, including gliding, hinge, saddle, and ball and socket joints. 1  Gliding joints, such as the ones between the carpals of the wrist, are found where bones meet as flat surfaces and allow for the bones to glide past one another in any direction.
