- Cartilage does not truly repaire; is this a correct statement? If yes, why?arrow_forwardThe menisci in the knee joint can be torn for a variety of reasons. Considering the structure of the menisci, would you expect these tears to heal on their own? Why or why not? a.The medial meniscus is attached to the tibial collateral ligament, so fibroblasts in the ligament can divide and differentiate into chondrocytes to repair the meniscus. b.Menisci tears do not heal on their own because the menisci are composed of hyaline cartilage and do not have an extensive blood supply. c.Menisci tears do not heal on their own because the menisci are composed of fibrocartilage and do not have an extensive blood supply. d.Menisci tears can heal quickly because of the nutrients surrounding them in the synovial fluid.arrow_forwardWhat do you mean by fibroblasts?arrow_forward
