    Study Notes

    White Fibro Cartilage

    • Not surrounded by perichondrium
    • Tough type of cartilage
    • Structure: Dense collagen fibers (type I), arranged in parallel bundles
    • Cartilage cells (chondrocytes) inside lacunae, present in rows between collagen bundles, embedded in very scanty matrix around them
    • Sites: Intervertebral discs, Symphysis pubis, Mandibular joint, Sternoclavicular joint

    Growth of Cartilage

    • Appositional growth: Growth by addition of new layers of cartilage to its surface by the activity of cells from inner layer of perichondrium (chondroblasts)
    • Interstitial growth: Growth of cartilage from inside by division of chondrocytes which proliferate and produce matrix around them
