Document Summary
Isolated cells become encased in their own matrix these are now mature, thus making them chondrocytes. When they mature, they make less matrix but maintain its integrity: collagen fibers in matrix, extend into lacunae and thus attach to chondrocytes. They get nutrients by the blood flow around the external cartilage perichondrium; as we move our cartilage, force is released, and thus fluid from blood vessels go to the cartilage. Wastes have to leave as well; as we move our cartilage, force is applied, and thus the water w/ wastes in it leaves. Different type here than in fibrous connective tissue (28 types remember) Gags are diff here than in fibrous connective tissue more likely to be sulfates or chondroitin here than glucose or galactose in fibrous: these give more wax like property. H"s are electrostatically attracted to negative charge on gags. Chondroblasts and chondrocytes synthesize and secrete all of these.
