Fragen in diesem Quiz (9)

  1. 1Bone tissue is static.
    1. ARichtig
    2. BFalsch
  2. 2Bone is made of the basic tissue known as [blank_start]connective[blank_end] tissue. There are two extracellular components: [blank_start]organic and inorganic[blank_end].
    The [blank_start]organic[blank_end] component (1/3 of ECM) is mainly [blank_start]collagen[blank_end] fibres to resist [blank_start]tension[blank_end], in a base of proteoglycans which hold water volume.
    The [blank_start]inorganic[blank_end] component (2/3 of ECM) is what makes bone hard. It contains [blank_start]hydroxyapatite[blank_end], which resists [blank_start]compression[blank_end].
    1. Aconnective
    2. Borganic and inorganic
    3. Corganic
    4. Dcollagen
    5. Etension
    6. Finorganic
    7. Ghydroxyapatite
    8. Hcompression
  3. 3Which statement about the cellular components of bone is FALSE?
    1. AOsteoblasts destroy bone.
    2. BOsteoblasts become osteocytes.
    3. COsteoclasts break down the ECM.
  4. 4Choose the statements about the structure of compact bone which are correct.
    1. AThe outer layer of compact bone (the periosteum) has holes in it.
    2. BIt is made up of osteons, which are longitudinal cylinders made of lamellae.
    3. CLamellae are the tubes of ECM, with collagen fibres aligned parallel to direction of growth.
    4. DThere are no nerves, arteries, or veins in the compact bone.
    5. EThe osteons maintain the osteocytes by providing them with nutrition.
  5. 5Choose the statement about osteocytes and compact bone which is CORRECT.
    1. AOsteons sit within lacunae.
    2. BCentral canals bring nutrients to osteocytes.
    3. CCanaliculi are smaller than central canals.
  6. 6The foramen is the opening of the central canal.
    1. ARichtig
    2. BFalsch
  7. 7Cancellous bone is trabeculous.
    1. ARichtig
    2. BFalsch
  8. 8The cavities between trabeculae are filled with...
    1. AECM.
    2. BMarrow.
    3. CCalcium.
    4. DOsteons.
  9. 9Blood cells in the marrow feed osteocytes.
    1. ARichtig
    2. BFalsch
