  1. What cause of cell injury does this demonstrate.
    • O2 deprivation of cell injury.
    • No O2 leads to reversible damage of heart muscles, if not fixed in time leads to MI thus the need for CPR.
  2. What cause of cell injury does this demonstrate.
    • Physical cause of cell injury
    • Also include physical trauma, electrocution, change in atm pressure.
  3. What cause of cell injury does this demonstrate.
    • Chemical cause of injury
    • Also include alcohol, illicit drugs.
  4. What cause of cell injury does this demonstrate.
    • Infectious cause of cell injury.
    • Also bacteria and fungi.
  5. What cause of cell injury does this demonstrate.
    • Immunologic cause of cell injury
    • - Bee sting leads to allergic reaction in which histamine is released and inflammation occurs. Dolor, calor, tumor, and rubor are seen.
    • Also autoimmune.
  6. What cause of cell injury does this demonstrate.
    • Genetic cause of injury
    • This demonstrates that cell injury could be caused by adverse reactions to drugs based on the person's specific sensitivity to certain drugs. (ex. G6PDH deficiency leads to hemolytic anemia when given a drug like chloroquine)
  7. What cause of cell injury does this demonstrate.
    • Nutritional cause of cell injury.
    • Too much nutrition leads to obesity.
    • Kwahorshikwor and marasmus. Cachexia.
  8. Myocardial necrosis. 2-12 hours. Then 12-24 hours neutrophils come in to digest the dead cells. Remember it is the severity of the hypoxia that determines how quickly the cell undergoes cell death.
  9. What type of necrosis is this.
    • Coagulative necrosis.
    • Ischemia related
  10. What type of necosis is this?
    • Liquefactive necrosis.
    • Hypoxic cells of CNS
    • Gangrenous necrosis
    • Ischemia and bacterial infection
  11. What type of necosis is this?
    • Caseous necrosis
    • Seen in tuberculosis infection
    • Granuloma
  12. What type of necosis is this?
    • Fat necrosis
    • Seen in the pancrease and peritoneal cavity
    • Caused by lipases
  13. What type of necosis is this?
    Fat necrosis of the enzymatic type
  14. What type of necosis is this?
    • Traumatic fat necrosis of the breast
    • ITS NOT CANCER
    • Mircocalcifications can be seen
  15. What type of necosis is this?
    • Fibrinoid necrosis
    • Fibrin and immune complexes in the walls of the arteries.
