Final answer:
The menisci of the knee are composed of fibrocartilage, providing padding and stability between the femur and tibia.
Step-by-step explanation:
The menisci of the knee are composed of fibrocartilage. They are C-shaped structures situated between the articulating surfaces of the femur and tibia, providing padding and stability to the knee joint. These menisci are configured to conform to the surfaces of the bones they protect, filling the gap between the round femoral condyles and the flatter tibial condyles. They are attached to the tibial condyles but not the femur, with the medial meniscus showing less movement due to its anchoring to the articular capsule and tibial collateral ligament. Fibrocartilage, which is also found in intervertebral discs, is characterized by its thick bundles of collagen fibers that give it its strength.
