Question

the skeletal system:Basic information Name Vicl Pre-Lab z. The Skeletal System: Basic Information 2Compact bone is composed of tiny tubes 1. Compact bone is composed of tiny tubes called systems o Each tiny tube has concentric rings of matrix around the central canal are called the amelize Bone cells are located in scattered spaces calledwn ls that interconnect the bone cells and the central canal are called the Short banes 2. Name six different bone shapes. Piat benemegulav bos Sesamoel rand Yellow bone marrow is present inside the medullancavity of the long bone while red bone marrow is found in thebeiwlze 3. 4. Describe the characteristies that each of these components gives to bone. Components of Extracellular Matrix Fibers Characteristic Ground substance

Explanation / Answer

Connective tissue found in bones is the main source of cells, fibers and ground substance together this make the extracellular matrix

Components of extracellular matrix Characteristics fibers

Connective tissue found in bones is the main source of cells, fibers and ground substance together this make the extracellular matrix

  • The fibers in extracellular matrix includes collagen fibers, elastic fibers and reticular fibers
  • In bone the matrix is made up of 95% of collagen fibers, and the reminder is ground substance
  • The extracellular matrix of bone is made up of osteoblasts whic secretes both collagen and ground substance, hence form into collagen fibrils
  • Collagen contains strands of repeating units gives the bone tensile strength and compressive strength
Ground substance
  • Ground substance is an amorphous gelatinous material in th extracellular spce which contains connective tissue and fiber
  • Ground substnace consists of large molecule called glycosaminoglycan, which linked together to form even larger molecule called proteoglycan
  • The main function are development, movement and proliferation fo tissues, and gives support water storage and binding
