Articular cartilage is a type of connective tissue that lines the surfaces of bones within joints. Its main function is to reduce friction and absorb shock during movement, helping to ensure smooth and pain-free joint movement. In order to perform this important role, articular cartilage needs a constant supply of oxygen and nutrients.
One way that articular cartilage receives these essential substances is through diffusion. The cartilage has a relatively poor blood supply compared to other tissues in the body, so it relies on diffusion to obtain oxygen and nutrients from the surrounding joint fluid. This joint fluid, known as synovial fluid, is produced by the synovial membrane and fills the space within the joint. It contains oxygen, nutrients, and other substances that are needed for the health of the cartilage.
Another way that articular cartilage receives oxygen and nutrients is through the process of imbibition. This occurs when the cartilage absorbs the joint fluid through tiny channels within its structure. Imbibition helps to keep the cartilage hydrated and nourished, allowing it to maintain its elasticity and cushioning properties.
Despite these mechanisms, the articular cartilage can sometimes become damaged or degenerate over time. This can lead to conditions such as osteoarthritis, which is characterized by the breakdown of the cartilage and the development of bone spurs. In order to maintain the health of the articular cartilage, it is important to engage in activities that put minimal strain on the joints, such as low-impact exercises like swimming or cycling. It is also important to maintain a healthy diet and avoid excess weight, as excess weight can put additional strain on the joints and lead to cartilage damage.
In conclusion, articular cartilage is an essential component of joints, helping to reduce friction and absorb shock during movement. It receives oxygen and nutrients through diffusion and imbibition from the surrounding joint fluid, but it is also important to take care of the cartilage through healthy lifestyle choices to maintain its health and prevent damage.
Articular Cartilage
Except in young children, damaged cartilage undergoes slow and often incomplete repair, primarily dependent on cells in the perichondrium which invade the injured area and produce new cartilage. Part A 2021, 27, 679—702. These joints are the meeting points of two bones. Rheumatoid arthritis and osteoarthritis are autoimmune diseases. In future experiments, small molecules that promote cartilage differentiation can be added to the hydrogel to achieve a faster and better repair effect.
Suppose all synarthrotic joints were fused in an individual. A synovial plane joint A person works an office job that requires them to be in a sitting position for 10 hours a day. Examples are the proximal radioulnar joint, and the joint between the first and second Atlantoaxial joint of the first and second vertebrae Condyloid Ellipsoidal Joints With the ability to move along two axes up and down, side to side , ellipse-shaped bone surfaces — one concave and one convex — are found primarily in the hand and wrist, and the foot. The Gel + cells groups had the highest scores with statistically significant differences at 6 and 12 weeks. Rheumatoid arthritis is caused by effects of aging and osteoarthritis is an autoimmune disease. It serves various functions like- storage of reserve fuels, protection of various tissues and organs, transportation of substances within the body, support to the body and its organs, binding of various tissues in our bodies, providing insulation to various organs and tissues, etc.
It contains cartilage tissue and white fibrous tissue. It is found in structures like the nose, ears, and areas where the ends of the ribs attach to the sternum, and in parts of the respiratory system like the trachea and larynx, where it helps give these parts their form but also gives them some flexibility. Any pain is not caused by damage to the cartilage itself, as cartilaginous connective tissues are aneural without a nerve network. In a small region of intervertebral disc, the axially arranged aggregates of chondrocytes C are seen to be surrounded by small amounts of matrix and separated by larger regions with dense The major stages of embryonic cartilage formation, or chondrogenesis, are shown here. Elastic cartilage makes up the outside of the ears and some of the nose. As might be expected of cells in an avascular tissue, chondrocytes exhibit low metabolic activity.
Cartilage damage: Symptoms, causes, diagnosis, and treatment
Photocurable silk fibroin-based tissue sealants with enhanced adhesive properties for the treatment of corneal perforations. If the damage is too extensive, the cartilage is replaced by a connective tissue scar. An octave refers to a factor of 2 in frequency. Low levels of oxygen mean chondrocytes primarily depend upon anaerobic metabolism. Which of the following best describes the causes of common forms of arthritis? Review and thoroughly understand the series of diagrams in. At least five samples from every group were used for the quantification.
The ulnar collateral ligament D. It is also in direct contact with the synovial fluid of the joint capsule. This layer protects the deeper layers from sheer stresses, but is very thin. A Extension-bending the leg at the knee or decreasing the angle between the upper and lower leg B Abduction-lifting the arm horizontally to form a right angle with the side of the body or moving a part away from the midline C Flexion-straightening parts at a joint so that the angle between them is increased D Adduction-moving a part in a circle or returning the arm from the horizontal position to the front of the body The hip joint has less freedom of movement than the shoulder joint because A the joint capsule of the hip is surrounded by muscles and the shoulder is not. The cartilage receives nutrition through the process of diffusion. The protoplasm inside content of the cell is clear, and the cells have one or two nuclei.
In the lower limbs, the weight-bearing properties of articular cartilage are unable to properly distribute weight and the shock-absorbant characteristics of cartilage are lost. Deep or Radial Layer Here, the chondrocytes begin to form columns along an axis of collagen fibrils. Recent advances in bioprinting using silk protein-based bioinks. These are located within lacunae surrounded by the matrix M which these cells secreted. There are several surgical options, depending on a number of factors, which include the age and activity level of the patient, how big the lesion is, and how long ago the injury happened. Dense connective tissue of perichondrium is shown here with hyaline and elastic cartilage.
Rheumatoid arthritis and osteoarthritis are caused by effects of aging. They are further subdivided into two categories- Loose connective tissue and Dense connective tissue. Hyaline cartilage cells metabolize glucose mainly by anaerobic glycolysis. Medial internal rotation is the turning of a limb on its longitudinal axis so its anterior surface moves toward the midline, whereas lateral external rotation is the turning of a limb on its longitudinal axis in the opposite direction. Rheumatoid arthritis and osteoarthritis are caused by effects of aging. It is surrounded by a membrane called the perichondrium, which provides nutrients to the cartilage since the cartilage tissue has no blood vessels of its own. Which of the following best describes the causes of common forms of arthritis? Lack of movement drives the synovial membranes to stop producing synovial fluid, which then causes friction to generate upon movement of the joints.
Fibrous cartilage is the toughest cartilage present in our body- and hyaline cartilage is the most abundant cartilage of our body. Injectable Ultrasonication-Induced Silk Fibroin Hydrogel for Cartilage Repair and Regeneration. It is an important source of nutrients for articular cartilage present in the cavity of synovial joints. Cells are not preserved by this method, but the lamellae, lacunae, and canaliculi of osteons Haversian systems are shown very well , noting osteons sectioned in various orientations. Chondronectin is a structural multi-adhesive glycoprotein.
Hyaline cartilage: Histological features and cells
In the respiratory tract, ears, and nose, cartilage forms the framework supporting softer tissues. They go home and sit until they go to bed. Cell viability, proliferation, and chondrogenesis in hydrogels. Silk Fibroin-Based Hydrogels and Scaffolds for Osteochondral Repair and Regeneration. Recent Advances on Bioprinted Gelatin Methacrylate-Based Hydrogels for Tissue Repair. Share on Pinterest Surgery for cartilage damage is generally a last resort.
