Questions and Answers
  • 1. 
    A slowly progressive disease of muscular arteries, in which the inner layer becomes thickened by fatty deposits and fibrous tissue.  
    • A. 

      Atherosclerosis

    • B. 

      Intima

    • C. 

      Lumen

    • D. 

      Foam cells

  • 2. 
    The inner most layer of the artery which is composed of a thin layer of endothelial cells which essentially  come in contact with the blood.
    • A. 

      Intima

    • B. 

      Media

    • C. 

      Adventitia

    • D. 

      Lumen

  • 3. 
    The “middle” and thickest layer of the artery and composed of smooth muscle  cells which constrict & dilate the vessel wall, thus assisting in the regulation of blood flow.
    • A. 

      Media

    • B. 

      Intima

    • C. 

      Adventitia

    • D. 

      Foam cells

  • 4. 
    The outer layer of the artery  which contain fibroblasts, collagen, blood vessels nerves, and lymphatics which all service the vessel.  
    • A. 

      Adventitia

    • B. 

      Media

    • C. 

      Parietal pericardium

    • D. 

      Foam cells

  • 5. 
    The opening  within the artery which provides a channel for blood flow
    • A. 

      Lumen

    • B. 

      Adventitia

    • C. 

      Foam cells

    • D. 

      Pericardium

  • 6. 
    The subendothelial  accumulation of a group of cells which are filled with lipids and appear as a “fatty streak” when examined under a microscope.  
    • A. 

      Foam cells

    • B. 

      Fibrous plague

    • C. 

      Lumen

    • D. 

      Adventitia

  • 7. 
    Provides a protective barrier from thrombotic substances (i.e. cholesterol). However, when injured the cells lose the protective barrier and will attract monocytes & smooth muscle cells.  
    • A. 

      Endothelial cells

    • B. 

      Smooth muscle cels

    • C. 

      Platelets

    • D. 

      Monocytes/Macrophages

  • 8. 
    Responsible for movement/contraction myofibrils within the cell and the synthesis of collagen, elastin, etc., which form the structure of the media layer in the artery.  During the “synthesis” state the cells provide receptors for LDL & platelet derived growth factor (PDGF), which will migrate from the media layer to the intima layer.
    • A. 

      Smooth muscle cells

    • B. 

      Platlets

    • C. 

      Endothelial cells

    • D. 

      Monocytes

  • 9. 
    Contain numerous biochemical “bombs” which are released into the bloodstream and upon impact attract more platelets, smooth muscle cell proliferation, and ADP & epinephrine which induces vasoconstriction  and an increased pressure gradient within the artery.  Blood to clot or stick together
    • A. 

      Platelets

    • B. 

      Smooth muscle cells

    • C. 

      Endothelial cells

    • D. 

      Monocytes/Macrophages

  • 10. 
    Once the intima layer has been injured due to whatever reason (HTN, smoking, etc.) the circulating monocytes enter the subendothelial space and become macrophages and the subsequent initiation of atherogenesis is begun.       
    • A. 

      Response to injury hypothesis

    • B. 

      Monocytes

    • C. 

      Endothelial cells

    • D. 

      Platlets
