Cartilage histology Understanding the MR appearance of normal articular cartilage requires some appreciation of the underlying histology. Histology of articular cartilage zones. Articular cartilage Perichondrium Which of the following features of metal-on-metal total hip arthroplasty does not allow for improved fluid film lubrication between the components? Hyaline cartilage has a “glassy” appearance and can be found on many articular surfaces as well as cartilage that provides structural support. While softening in the initial stage is reported and sometimes used as an indicator of early OA, there is a lack of data relating the macroscopic appearance of cartilage to its mechanical and histological properties in all stages of degeneration. The bulk of this tissue consists of an extracellular matrix composed of … a healing response is initiated with hematoma, stem cell migration, and vascular ingrowth. 75.98.171.133. Tested Concept, Decreased collagen content and decreased modulus of elasticity, Increased chondroitin sulfate concentration, (OBQ04.3) Functions of articular cartilage: Functions of the matrix: 2, 7 Matrix deformation produces mechanical, electrical and chemical signals, affecting the functions of chondrocytes. Mechanical injury to the articular cartilage is a key risk factor in joint damage and predisposition to osteoarthritis. Articular Cartilage is a specialised form of hyaline cartilage. Hyaline cartilage is the most widespread cartilage and found in the nose, larynx, trachea, bronchus, ribs, and articular surfaces of bones. ; Elastic - is found in the external ear, epiglottis and larynx. Unlike most hyaline cartilage, articular hyaline cartilage does not have a perichondrium on either surface.. Free (articular) Surface - exposed to synovial fluid within the joint. The perichondrium harbors the blood supply serving the cartilage and a small neural component. because of the low turnover, articular cartilage is susceptible to AGEs accumulation. While the intricate ultrastructure of articular cartilage is critical for proper function, these same properties create challenges for cartilage restoration. 020 trachea connective tissue fibroblast plasma cell H&E Webscope Imagescope 040 trachea H&E Webscope Imagescope 040N hyaline cartilage 1.5um section H&E Webscope Imagescope 126 trachea, esophagus H&E Webscope Imagescope. When evaluating articular cartilage, look for any surface damage that has occurred from normal wear and tear or surgical models. Thus, matrix also plays a role in recording a loading history of the articular cartilage. Chondrocytes + extracellular matrix containing type II collagen fibers, GAGs, proteoglycans, and multiadhesive glycoproteins. 1 Fat-suppressed three-dimensional fast spoiled gradient-recalled echo imaging Cartilage is a flexible connective tissue found in many parts of the body. Bone Histology. Tested Concept, (OBQ12.203) Articular cartilage is made up of four basic biological layers or zones. Hyaline cartilage contains type II collagen fibers and a highly-hydrated ground substance. Elastic cartilage - elastic fibers and type II collagen; Fibrocartilage - type I and II collagens; Cartilage is avascular and its cells rely on diffusion for nutrients. Hyaline cartilage is the most widespread cartilage and found in the nose, larynx, trachea, bronchus, ribs, and articular surfaces of bones. (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.

It is made up of cells called chondroblasts and chondrocytes, (chondro - cartilage) and extracellular matrix, made up about 10% aggrecan, 75% water, and a … 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). cartilage exhibits stress-shielding of the solid matrix components due to its high water content, the incompressibility of water, and the structural organization of the proteoglycan and collagen molecules. 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. Junqueira, p.157 26. Articular cartilage - histology slide This histology slide is from articular cartilage. Provides a low-friction gliding surface. © 2020 Springer Nature Switzerland AG. No perichondrium Collagen fibers - arranged as gothic arches Chondrocytes - in vertial rows. The avascular nature of articular cartilage and its relatively low density of chondrocytes with low mitotic activity are a disadvantage to healing. All the best! Articular cartilage is specifically the smooth, white tissue covering the ends of bones where they come together to form joints. Following an intra-articular fracture, in addition to mechanical disruption and cartilage necrosis, the following inflammatory cytokines are released, contributing to articular damage and the eventual development of post-traumatic arthritis: occurs when laceration travels through tidemark and penetrates subchondral bone, fibrocartilage produced by undifferentiated marrow mesenchymal stem cells. J Bone Joint Surg Am 64(3):460–466, Huey DJ, Hu JC, Athanasiou KA (2012) Unlike bone, cartilage regeneration remains elusive. is not surrounded by a perichondrium and is partly vascularised. 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 strong, flexible and semi-rigid supporting tissue. It is very important that your samples are dissected properly. Grossly normal articular cartilage from knees and ankles of a fresh cadaver were used in the study. A 32-year-old runner sustains a trimalleolar left ankle fracture.

Hyaline cartilage is the most abundant type of cartilage. Last reviewed: October 29, 2020 Reading time: 3 minutes Hyaline cartilage is the most common of the three types of cartilage. Cartilage support of other tissues throughout the respiratory tract is also prominent. 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. Cartilage support of other tissues throughout the respiratory tract is also prominent. The perichondrium (Figure 7–2) is a sheath of dense connective tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient (Figure 1).Articular cartilage is devoid of blood vessels, lymphatics, and nerves and is subject to a harsh biomechanical environment. Arthritis Rheum 50(12):3915–3924, Sophia Fox AJ, Bedi A, Rodeo SA (2009) The basic science of articular cartilage: structure, composition, and function. 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. Articular cartilage is usually found in layers of between 2 and 4 mm thick. All the best! Bone consists of an outer layer of periosteum (subdivided into an outer fibrous & inner cellular layer), similar to cartilage, but the inner cellular layer consists of osteoprogenitor cells instead chondrogenic cells.Articular bone regions covered by hyaline cartilage do not have a periosteum. No meniscus tear is identified, but the articular cartilage of the femoral condyles is noted to be twice as thick as normal values.

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. For example, a mouse hind limb should be dissected well, leaving as little remaining soft and connective tissue as possible. It also is different as it has type I and II collagen in its matrix whereas hyaline has only type II. • Is deep to the basal layer and separates the true articular cartilage from the deeper cartilage that is a remnant of the cartilage anlage, which participated in endochondral ossification during longitudinal growth in childhood. 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. Articular cartilage, a metabolically active tissue, has viscoelastic properties and is composed of chondrocytes (approximately 1%) and an extracellular matrix that consists mainly of water (65% to 80%), proteoglycan, and collagen.
