  23. What does simple cuboidal mean?
    Single layer of cube shaped cells
  24. What is the function of simple cuboidal tissue?
    Secretion and absorption
  25. Where are simple cuboidal tissues found?
    Glands of the body(ovaries, salivary glands, pancreas)
  26. What does simple columnar mean?
    Single layer of column shaped cells
  27. What is the function of simple columnar tissues?
    Secretion and absorption
  28. Where are simple columnar tissues found?
    Digestive tract(stomach-->anal canal)
  29. What does pseudostratified columnar mean?
    Single layer of cells with varying heights
  30. What is the function of pseudostratified columnar tissues?

  49. What are mesenchymal cells?
    Stem cells of the connective tissue proper
  50. What are Fibrocyte cells?
    Cells that produce extracellular fibers(collagen or elastic fibers)
  51. What are adipose cells?
    Cells specialized to store lipid energy reserves
  52. What are elastic cells?
