82CHAPTER 3TISSUESTABLE 3.6Mature Connective Tissue: Supporting Connective Tissue—CartilageB. FIBROCARTILAGEDescription:Chondrocytes are scattered among clearly visible thick bundles of collagen fibers within the extracellular matrix of fibrocartilage.Fibrocartilage lacks a perichondrium.Location:Pubic symphysis (point where hip bones join anteriorly), intervertebral discs (discs between vertebrae), menisci (cartilage pads) of knee,and portions of tendons that insert into cartilage.Function:Support and joining structures together. With a combination of strength and rigidity, this tissue is the strongest of the three types of cartilage.LacunacontainingchondrocyteLacunacontainingchondrocyteNucleus ofchondrocyteNucleus of chondrocyteCollagen fibersin groundsubstance200xSectional view of fibrocartilage of intervertebral discFibrocartilageVertebraIntervertebral discLM400xLMA. HYALINE CARTILAGEDescription:Hyaline (hyalinos=glassy) cartilage contains a resilient gel as its groundsubstance and appears in the body as a bluish-white, shiny substance (can stain pink orpurple when prepared for microscopic examination). The fine collagen fibers are notvisible with ordinary staining techniques, and prominent chondrocytes are found inlacunae. Most hyaline cartilage is surrounded by a perichondrium. The exceptions arethe articular cartilage in joints and the cartilage of epiphyseal plates, the regions wherebones lengthen as a person grows.Location:Most abundant cartilage in the body, it is found at the ends of long bones, anteriorends of ribs, nose, parts of larynx, trachea, bronchi, bronchial tubes, and embryonic andfetal skeleton.Function:Provides smooth surfaces for movement at joints, as well as flexibility and support. Itis the weakest of the three types of cartilage and can be fractured.Mark NielsenNucleus ofchondrocyteLacunacontainingchondrocytePerichondrium200xGroundsubstanceSectional view of hyaline cartilageof a developing fetal boneHyaline cartilageFetusSkeletonLM400xLM6000xSEMLacunaChondrocyteExtracellular matrixHyaline cartilageSteve Gschmeissner/Science Source Images
3.5CONNECTIVE TISSUE83mineral salts (mostly calcium and phosphates), which givebone its hardness and compressive strength, and collagen fib-ers, which give bone its tensile strength. The lamellae are re-sponsible for the compact nature of this type of bone tissue.2. Lacunae(la-KOO-ne¯; singular islacuna,prounced la-KOO-na) are small spaces between lamellae that contain maturebone cells calledosteocytes.
