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 six major types of synovial joints are. ball-and-socket, condyloid, gliding, hinge, pivot, and saddle. A ball-and-socket joint consists of a. bone with a globular head that articulates with a cup-shaped cavity of another bone. A ball-and-socket joint allows a. wider range of motion than any other type of joint.
