  1. A cellular adaption observable in uterine cervical epithelium is ?
    dysplasia
  2. What are the consequences when a cell is forced into anaerobic glycolysis?
    increased lactic acid and inadequate ATP.
  3. Dytrophic calicfication:
    occurs in dying or dead tissues and observed in chronic lesions
  4. Cellular swelling is:
    evident early in all types of cellular injury
  5. What is not reversable?
    karyolysis
  6. Aging :
    none of the above
  7. In aging, cross-lnking implies?
    cell permeability decreases
  8. When does cellular injury occur?

  9. What are the four biochemical themes that are important to cell injury?
    ATP depletion, oxygen and oxygen-derived free radicals, intracellular calcium and loss of calicum steady state, and defects in membrane permiability
  10. Apoptosis:
