The 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.

Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
