Hyaline cartilage - wikipedia Hyaline cartilage Hyaline cartilage Light micrograph of hyaline cartilage showing microanatomy of chondrocytes and organelles, lacunae and matrix. Identifiers MeSH D051457 TH H2. 00.03. 5.00015 Anatomical terminology ( edit on Wikidata ) Hyaline cartilage is glass - like ( hyaline ) but translucent cartilage. It is found on many joint surfaces. It is pearl - grey in color with firm consistency and has a considerable amount of collagen. It contains no nerves or blood vessels, and its structure is relatively simple.

This membrane contains vessels which provide the cartilage with nutrition through diffusion. Hyaline cartilage matrix is primarily made of type II collagen and chondroitin sulphate, both of which are also found in elastic cartilage. Hyaline cartilage exists on the ventral ends of ribs, in the larynx, trachea, and bronchi, and on the articulating surfaces of bones. It gives the structures a definite but pliable form. Presence of collagen fibres makes such structures and joints strong, but with limited mobility and flexibility. Hyaline cartilage is the most prevalent type of cartilage. It also forms the temporary embryonic skeleton which is gradually replaced by bone, and the skeleton of elasmobranch fish. Microanatomy When a thin slice of hyaline cartilage is examined under the microscope, it is shown to consist of cells ( chondrocytes ) of a rounded or bluntly angular form, lying in groups of two or more in a granular, or almost homogeneous matrix. The matrix, itself, is produced by chondrocytes are cartilage cells that produce the matrix. When arranged in groups of two or more, chondrocytes have rounded, but generally straight outlines, where they are in contact with each other, and in the rest of their circumference are rounded. They consist of translucent protoplasm with fine interlacing filaments and minute granules are sometimes present. Embedded in this are one or two round nuclei, having the usual intranuclear network. The cells are contained in cavities in the matrix, called cartilage lacunæ. These cavities are actually arteficial gaps formed from the shrinking of the cells during the staining and setting of the tissue for examination. The inter-territorial space between the isogenous cell groups contains relatively more collagen fibres, allowing it to maintain its shape while the actual cells shrink, creating the lacunae. This constitutes the so - called ' capsule ' of the space. Each lacuna is usually occupied by a single cell, but during mitosis, it may contain two, four, or even eight cells. Articular cartilage Articular cartilage is hyaline cartilage on the articular surfaces of bones, and lies inside the joint cavity of synovial joints, bathed in synovial fluid produced by the synovial membrane which lines the walls of the cavity. Though it is often found in close contact with menisci and articular disks, articular cartilage is not considered a part of either of these structures, which are made entirely of fibrocartilage. The biochemical breakdown of the articular cartilage results in osteoarthritis - the most common type of joint disease. Osteoarthritis affects over 30 million individuals in the United States alone, and is the leading cause of chronic disability amongst the elderly.
