It can bend a bit, but resists stretching. Figure A displays a schematic of the zones of articular hyaline cartilage. Articular cartilage is like hyaline cartilage except it lacks a perichiondrium which affects is ability to nourish, remove waste & repair Hyaline cartilage is the most widespread cartilage and found in the nose, larynx, trachea, bronchus, ribs, and articular surfaces of bones. The cartilage is structurally divided into three zones, each with a unique cellular morphology and arrangement of the type II collagen fibers . Summary. Articular cartilage Perichondrium Histology of Articular Cartilage Repair. Junqueira, p.157 26. Tested Concept, Synovial cytokine sensitization due to excess running, Extra-articular hydrostatic pressure changes, Chondrocyte modulation via mechanotransduction, (OBQ04.78) Articular cartilage serves as a load-bearing elastic material that is responsible for the frictionless movement of the surfaces of articulating joints. Articular cartilage is made up of four basic biological layers or zones. Provides a low-friction gliding surface. Histology slide courtesy of Education Interactive Human Histology Photo CD. As with all types of cartilage, the absence of blood vessels and lymph vessels creates a very slow metabolic environment. 1 Fat-suppressed three-dimensional fast spoiled gradient-recalled echo imaging 1 Collagen provides the tensile strength of articular cartilage. Articular Cartilage is a specialised form of hyaline cartilage. Histology - Cartilage. Articular cartilage - histology slide This histology slide is from articular cartilage. ; Elastic - is found in the external ear, epiglottis and larynx. The subset of 17 patients with bone bruises and combined articular cartilage pathology were 3.4 times more likely to be symptomatic at 6-year follow-up than those without articular cartilage pathology (P = 0.04). Articular cartilage is usually found in layers of between 2 and 4 mm thick. Welcome to Articular Engineering, the leading supplier of customized orthopaedic cells and tissue cultures to pharmaceutical, biotechnology and research organizations. ... only type of growth that fibrocartilage and articular cartilage do Its main function is to connect bones together. Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints and nerves, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The surface of hyaline cartilage is surrounded by the perichondrium, a transitional zone between cartilage and the surrounding connective tissue, but articular cartilage lacks the perichondrium. Hope, you have got the basic idea about cartilage histology along with hyaline cartilage histology, hyaline cartilage function, cartilage function, cartilage ppt, elastic cartilage histology, fibrocartilage histology, costal cartilage histology and others. These slides are good examples of mature hyaline cartilage with its abundant matrix and spaces, lacunae, occupied by cells, … Elastic cartilage is covered by the perichondrium and found in the external ear, auditory tube, and epiglottis. ; Elastic - is found in the external ear, epiglottis and larynx. Cartilage histology Understanding the MR appearance of normal articular cartilage requires some appreciation of the underlying histology. 7. Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints and nerves, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. Cartilage is a flexible connective tissue found in many parts of the body. Hyaline Cartilage. Which type of cartilage forms the articular surface on bones? The photomicrographs show the main features of (b) hyaline cartilage, (c) elastic cartilage, and (d) fibrocartilage. Constituents of cartilage. Conclusions. type II collagen accounting … The clear site-specific differences in normal cartilage must be taken into consideration when characterizing the pathoetiology of OA models. Cartilage is a strong, flexible and semi-rigid supporting tissue. Dense irregular connective tissue surrounding hyaline cartilage (with the exception of articular cartilage). All the best! Functions of hyaline cartilage • Articular cartilage provides smooth surface for movement at joints • Though it is flexible, it provides support because of its firmness • Firmness of the cartilage keeps the lumen of trachea and bronchi patent 19. She undergoes open reduction and internal fixation and is kept non-weightbearing after surgery. 3. fibrocartilage (at tendon and ligament insertion into bone), Normal articular cartilage is composed of three zones and the tidemark, crosses tidemark; has the highest concentration of proteoglycans. Hyaline cartilage is the most widespread cartilage and found in the nose, larynx, trachea, bronchus, ribs, and articular surfaces of bones. Which of the following features of metal-on-metal total hip arthroplasty does not allow for improved fluid film lubrication between the components? Articular cartilage serves a vital role in maintaining joint function by minimising friction and distributing load. Is a precursor of bone. Articular cartilage contains a relatively small number of chondrocytes. 75.98.171.133. Not affiliated Fibrocartilage lacks a perichondrium and is found in intervertebral discs, temporomandibular joint disc, knee meniscus, sternoclavicular joint disc, pubic symphysis, and insertion sites of tendon and ligament into bone. It also is different as it has type I and II collagen in its matrix whereas hyaline has only type II. When evaluating articular cartilage, look for any surface damage that has occurred from normal wear and tear or surgical models. Cartilage: The three types of cartilage There are three types of cartilage: Hyaline - most common, found in the ribs, nose, larynx, trachea. Tested Concept, (SAE07HK.93) (a) There are three types of adult cartilage distributed in many areas of the skeleton, particularly in joints and where pliable support is useful, as in the ribs, ears, and nose. Articular cartilage is specifically the smooth, white tissue covering the ends of bones where they come together to form joints. Substantial changes in articular cartilage composition and mechanical properties occur during the development of osteoarthritis (OA). What part of the articular cartilage has the highest concentration of proteoglycans and the lowest concentration of water? Grossly normal articular cartilage from knees and ankles of a fresh cadaver were used in the study. transforms the articulating ends of the bones into lubricated, wear-proof, slightly compressible surfaces, which exhibit very little friction. covers cartilage. Well-known for their inability to heal, articular cartilage injuries often degenerate inexorably to disastrous impairment. Columns of isogenous groups during ossification Regeneration by appositional growth from perichondrium; the chondroblasts from perichondrium invade the damaged area and generate new cartilage in extensively damaged areas the cartilage is replaced by dense connective tissue is not surrounded by a perichondrium and is partly vascularised. The surface of hyaline cartilage is surrounded by the perichondrium, a transitional zone between cartilage and the surrounding connective tissue, but articular cartilage lacks the perichondrium.
