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.
Ball and socket joints allow for stable movement in several directions without slippage. Like a saddle joint, the ball and socket joint allows bending in several directions without slipping, creating a highly stable, strong joint. The hip joint (femur-acetabulum) is an example of a ball and socket synovial joint.here are six types of synovial joints: gliding, condoloid, saddle, hinge, ball and socket, and pivot joints. Gliding joints allow for smooth movement in several directions along a plane or other smooth surface.
