Apart from hyaline cartilage, our body has two more types of cartilages:Elastic cartilage:This has a high concentration of elastic fibers and is present in ECM. Elastic cartilage has a yellowish appearance and is the most pliable cartilage amongst all cartilages in our body. These cartilages do not calcify. The chondrocytes in elastic cartilage are present in thread-like networks which are made up of elastic fibers. The primary function of elastic cartilage is to provide strength and support. It also helps in maintaining the shapes of certain structures like external ears. Elastic fiber is also present in the epiglottis and middle ear’s auditory tube (eustachian tube).Fibrocartilage:These cartilages are found mainly in the intervertebral discs and also where the tendon connects to the bone. Fibrocartilages contain extremely large bundles of collagen and are very tough and strong tissues. They are similar to other fibrous tissues but have chondrocytes and cartilage ground substance. These cartilages can resist shear forces and compression. The strength of fibrocartilage comes from having thick and dense collagen layers and alternating layers of hyaline cartilage. Fibrocartilage does not contain a perichondrium and they usually form a transitional layer between hyaline cartilage and a ligament or tendon.
