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.
Synovial joints, sometimes called diarthrosis, are the most movable type of joint in the body. Joints are formed where bones come together. In this lesson, we'll explore the six types of synovial joints and discuss their functions.s shown on this illustration, the six types of synovial joints include the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. These joints are found throughout the body; however some locations serve as better examples than others. To begin our investigation, let's focus on the pivot joints.
