Cartilage

Cartilage is a type of dense connective tissue in the body. It is made of cells called chondrocytes embedded in a matrix, strengthened with fibers of collagen and sometimes elastin, depending on the type of cartilage. Cartilage serves to provide structure and support to the body's other tissues without being as hard or rigid as bone. It can also provide a cushioning effect in joints. Its mechanical properties are intermediate between bone and dense connective tissue like tendon.

Cartilage is found in many areas in the body including the articular surface of the bones, the rib cage, the ear, the nose and the intervertebral discs. Unlike other connective tissues, cartilage does not contain blood vessels. The chondrocytes are fed by diffusion, helped by the pumping action generated by compression of the articular cartilage or flexion of the elastic cartilage. Thus, compared to other connective tissues, cartilage grows and repairs more slowly.
