Cartilage is a significant auxiliary segment of the body. It is a firm tissue however is milder and significantly more adaptable than bone. Cartilage is comprised of particular cells called chondrocytes. These chondrocytes produce a lot of extracellular framework made out of collagen filaments, proteoglycan, and elastin strands. There are no veins in ligament to flexibly the chondrocytes with nutrients. This ligament covers the articular surface and has a smooth shape that permits skimming of the closures of the bones and opposes shear. It conforms to 10% to 20% of articular ligament thickness and has the most noteworthy collagen substance of all the zones. The collagen fibrils are thickly pressed and are adjusted in an exceptionally sorted out way corresponding to the articular surface. The chondrocytes in this zone are prolonged in shape. This lies straightforwardly on the subchondral bone and contains little cells in a chondroid network that has apatitic salts dissipated through it.
