      Fibers, cells and ground substance.

    • B. 

      Neurons and neuroglial cells.

    • C. 

      Actin and myosin.

    • D. 

      Sheets of cells that cover and line other tissues.

    • E. 

      Dendrites, cartilage, perikaryon.

  • 4. 
    Epithelial tissue can function in the manufacture of secretions and excretions.
    • A. 

      True

    • B. 

      False

  • 5. 
    What two surface do epithelial cells contain?
    • A. 

      Rough and smooth.

    • B. 

      Granular and jagged.

    • C. 

      Basement membrane and brush border.

    • D. 

      Apical and basal.

    • E. 

      Kerotinized and stratified.

  • 6. 
    The apical surface of epithelial tissue faces the underlying connective tissue and the basal surface faces the lumen.
    • A. 

      True

    • B. 

      False

  • 7. 
    What do epithelial cells rely on to provide oxygen and nutrients and why?
    • A. 

      Rely on osmosis to absorbs nutrients from the external source due to loose connective cellular matrixs.

    • B. 

      Rely on underlying connective tissue and are vascular.

    • C. 

      Rely on goblet cells to provide nutrients because of the pinocytosis actions of the goblet cells.

    • D. 

      Transport RNA delivers the nutrients to the cells because Epithelial cells lack ATP to produce their own nutrition.

    • E. 

      Rely on underlying connective tissue and are avascular.

  • 8. 
    Junctional complexes connect the lateral surface to neighboring cells, leaving little room for ___________.

      Polar.

    • B. 

      Stable.

    • C. 

      Columnar.

    • D. 

      Innervated.

    • E. 

      Filtered.

  • 10.

    • B. 

      Matrix-filled channels.

    • C. 

      Flagella.

    • D. 

      Oviduct.

    • E.

      A gluey substance called Mucin.

    • E. 

      The fusion of the outermost layers of the plasma membranes of adjoining cells.

  • 14.
