- Adult hyaline articular cartilage is progressively mineralized at the junction between cartilage and bone.
- A mineralisation front advances through the base of the hyaline articular cartilage at a rate dependent on cartilage load and shear stress.
- The two bone surfaces at the joint are both covered in hyaline cartilage and joined by strands of fibrocartilage.
- There is rarely any clear line of demarcation between fibrocartilage and the neighboring hyaline cartilage or connective tissue.
- Fibrocartilage is never found alone, but is always found in association with hyaline cartilage or dense fibrous connective tissue.
- Articular cartilage is composed mainly of water, proteoglycans, and collagen.
- Stimulation of chondrogenesis in articular cartilage explant cultures by exposure to PEMF. I. Proteoglycan homeostasis.
- The synovial membrane is inflamed and thickens, the articular cartilage is damaged, fibrous tissue invades it.
- It is then termed articular calcified cartilage.
- In places, like joint surfaces, the bone will be covered with smooth articular cartilage.
- Growth and development Cartilage in fetal development In embryogenesis, most of the skeletal system is derived from the mesoderm germ layer.
- Osteoblasts are involved in forming bone trabeculae on the remains of the calcified cartilage.
- The new cells derive from the perichondrium and occur on the surface of the cartilage model.
- The cartilage model would grow in length by continuous cell division of chondrocytes, which is accompanied by further secretion of extracellular matrix.
- The chondroblasts secrete cartilage matrix, producing a cartilage model consisting of hyaline cartilage.
- Elastic cartilage is similar to hyaline cartilage but contains elastic bundles ( elastin) scattered throughout the matrix.
- There are three main types of cartilage: hyaline, elastic and fibrocartilage.
- The chondrocytes are fed by diffusion, helped by the pumping action generated by compression of the articular cartilage or flexion of the elastic cartilage.
- Long bone growth stops when the hyaline cartilage stops reproducing itself and fully converts to bone.
- Treatment of deep cartilage defects in the knee with autologous chondrocyte transplantation.
- Cartilage generally has very limited repair capabilities.
- Autologous chondrocyte implantation for cartilage repair: monitoring its success by magnetic resonance imaging and histology.
- Cartilage is composed of cells called chondrocytes which are dispersed in a firm gel-like ground substance, called the matrix.
- This is because the calcified matrix is much less hydrated than hyaline cartilage.
- In a long bone it is a thin disc of hyaline cartilage that is positioned transversely between the epiphysis and metaphysis.
- Cartilage is retained in the epiphyseal plate, located between the diaphysis (shaft) and the epiphysis (end) of the bone.
- A cement line demarcates articular calcified cartilage from subchondral bone.
- The matrix of cartilage acts as a barrier, preventing the entry of lymphocytes or diffusion of immunoglobulins.
- Damaged cartilage is usually replaced by fibrocartilage scar tissue.
- Stimulation of proteoglycan synthesis in human osteoarthritic cartilage by PEMF. Trans.
- Mitchell N, Shepard N. The resurfacing of adult rabbit articular cartilage by multiple perforations through the subchondral bone.
- Lesser the chondrocytes present, lesser is the synthesis of cartilage matrix.
- At equilibrium, the local amount of Gd-DTPA 2- within the cartilage matrix is inversely proportional to the local concentration of glycosaminoglycan.
- Stimulation with pulsing electromagnetic fields acts synergistically with growth factors to increase cartilage matrix synthesis.
- Cartilage is composed of collagen and elastic fibers.
- Hyaline cartilage is a rather hard, translucent material rich in collagen and proteoglycan.
- The "skeleton" of an embryo is composed of fibrous CT membranes (formed from mesenchyme and hyaline cartilage) that are loosely shaped like bones.
- Most joints are composed of cartilage, joint space, fibrous capsule, synovium, and ligaments.
- Much like other connective tissue, cartilage is composed of cells, fibers and a matrix.
- It has features intermediate between dense connective tissue (which has an abundance of Type I Collagen fibers) and hyaline cartilage.
- Fibrocartilage is a type of cartilage consisting of a dense matrix of collagen fibers giving discs great tensile strength.
- The protein made by this gene forms type II collagen, a molecule found mostly in cartilage and in the clear gel that fills the eyeball (the vitreous).
- The solid phase of articular cartilage consists primarily of type II collagen and aggrecan, a chondroitin and keratan sulfate proteoglycan.
- The continuous replacement of cartilage by bone results in the obliteration of the epiphyseal plate, termed the closure of the epiphysis.
- The periosteal cells proximal to the fracture gap develop into chondroblasts and form hyaline cartilage.
- Replacement of the hyaline cartilage begins in the center of the diaphysis = primary ossification center and spreads toward epiphyses.
- A band of cartilage called an epiphyseal plate remains between the primary ossification center and each secondary center.
- Other types of tissue found in bones include marrow, endosteum and periosteum, nerves, blood vessels and cartilage.
- Cartilage is avascular (contains no blood vessels) and nutrients are diffused through the matrix.
- As the fetus matures, the cartilage and connective tissue change into bone.
- Chondrodystrophies are a group of diseases characterized by disturbance of growth and subsequent ossification of cartilage.
- Endochondral ossification occurs in long bones, such as limbs; the bone is formed from cartilage.
- These areas of cartilage are known as secondary centers of ossification.
- In a developing fetus, cells in the cartilage skeleton begin to break down.
- Osteoclasts break down the calcified matrix and are replaced with bone-building osteoblasts that deposit bone in place of calcified cartilage.
- Some joints are immovable, e.g., those that connect the bones of the skull, which are separated merely by short, tough fibers of cartilage.
- Fibrocartilage is a tough, dense, fibrous material that helps fill in the torn part of the cartilage.
- Cartilage is found in the joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks.
- Cartilage is found in many places in the body including the joints, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs.
- Instability of a joint can over time lead to wear of the cartilage and eventually to osteoarthritis.
- The diaphysis and both epiphyses of a long bone are separated by a growing zone of cartilage (the epiphyseal plate).
- Zone of resting cartilage.
- Some organisms have a skeleton consisting entirely of cartilage and without any calcified bones at all, for example sharks.
- Cartilage can be replaced surgically through chondroplasty.
