Bursae and synovial fluid are the two structures that are involved in reducing friction in joints. Bursae are small fluid-filled sacs that sit between bones and soft tissues, reducing friction between them. Synovial fluid is a viscous fluid that lubricates the joints and reduces friction between bones during movement. Accessory ligaments provide stability to the joints, while the labrum is a cartilaginous structure that helps to deepen the joint socket and stabilize the joint. Therefore, options 3 and 4 are incorrect.
