The human skeletal system comes packaged with 206 bones and three types of cartilage.Hyaline cartilage is found in the embryonic skeleton, fibrocartilage is found in the intervertebral disks, and elastic cartilage is found in the epiglottis, larynx, and the outer ear.As its name suggests, elastic cartilage is significantly more pliable than either hyaline or fibrocartilage. © 2003 by Saunders, an imprint of Elsevier, Inc. Fibrocartilage may hold up in smaller lesions that are protected from heavy weight loading. In contrast, hyaline cartilage is the weakest type of cartilage composed of fewer collagen fibres. It is the only type of cartilage that contains type I collagen in addition to the normal type II. a specialized, fibrous connective tissue present in adults, and forming most of the temporary skeleton in the embryo, providing a model in which most of the bones develop, and constituting an important part of the organism's growth mechanism; the three most important types are hyaline cartilage, elastic cartilage, and fibrocartilage. This type of cartilage is especially strong and durable, so it appears in areas where these traits are needed. Elastic cartilage, which is yellow in appearance, is more pliable…, The third type, called fibrocartilage, has a large proportion of dense collagen bundles oriented parallel. Fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes. Fibrocartilage. The TFCC keeps the forearm bones (radius and ulna) stable when the hand grasps or the forearm rotates. The triangular fibrocartilage complex (TFCC) is a network of ligaments, tendons, and cartilage that sits between the ulna and radius bones on the small finger side of the wrist. features of fibrocartilage tissue are (6): These ends are known as the articulating surface. Elastic cartilage, which is yellow in appearance, is more pliableâ¦. The TFC is an articular discus that lies on the pole of the distal ulna.It has a triangular shape and a ⦠A. Spinal Tendon B. Costal Cartilage C. Thoracic Cartilage D. Vertebral Gel Sac E. Intervertebral Disc Feedback: Good work; your answer is correct! However, in larger lesions, fibrocartilage is not durable enough to withstand the forces within the knee and breaks down over time. It is the only type of cartilage that possesses both type I and type II collagen. It owes its flexibility and toughness to the fibrous tissue, and its elasticity to the cartilaginous tissue. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, Seventh Edition. What is the fibrocartilage padding in between the vertebrae called? If hyaline cartilage is torn all the way down to the bone, the blood supply from inside the bone is sometimes enough to start some healing inside the lesion. Hyaline cartilage covers the ends of bones. Fibrocartilage consists of a combination of white fibrous tissue and typical cartilaginous tissue. It is the only type of cartilage that contains type I collagen in addition to the normal type II. The triangular fibrocartilage arises from the superior aspect of the radial side of the distal radial-ulnar joint (sigmoid notch) and attaches to the ulna at the fovea at the base of the ulnar styloid. It is the only type of cartilage that contains Type I collagen in addition to the normal type II. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Thus, this is the key difference between fibrocartilage and hyaline cartilage. White fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. Triangular fibrocartilage disc. The TFCC is composed of the triangular fibrocartilage and the ulnocarpal ligaments. The wrist joint is one of the most complex and frequently used joints in the human body, and the triangular fibrocartilage complex is the fulcrum of wrist bending activity. What does FIBROCARTILAGE mean? The mechanics of wrist activity have been described by bone and joint specialists as involving the transfer of load weights from the lower arm bones ⦠Information from Encyclopaedia Britannica a large number of fibers fibrocartilage callus the TFCC ⦠is.
