Answer:
menisci
Explanation:
Some synovial joints such as that of knees have crescent-shaped pads. These pads are made up of fibrocartilage and are present between the articular surfaces of the bones. These cartilaginous pads are attached to the fibrous capsule and are called articular discs or menisci.
The function of the menisci is to serve in shock absorption and minimize the wear and tear of the joint. Meniscus also allows the articulating bony surfaces to fit properly and facilitate an adaptable surface for combined movements. Meniscus serves to distribute the weight over a greater contact surface and thereby makes the joint stable. It also spreads the synovial lubricant across the articular surfaces of the joint.
