1.3 Patterns of Cell Death Flashcards
Irreversible injury is the point of no return
T or F
T
2 types of Cell Death
Apoptosis and Necrosis
Programmed cell death
No leaking out of cellular contents so there is no inflammation
Usually single cells
Apoptosis
Pathological cell death:
Leaking out of cellular contents so there is inflammation
Usually group of cells (Tissue)
Necrosis
In apoptosis, the cell undergoes?
Shrinkage
In necrosis, the affected cells is?
Swelling
What is the earliest change in necrosis?
Cellular swelling
Type of Necrosis:
Happens in solid organs like kidneys, spleen
Coagulative Necrosis
Necrosis:
Type Characterized by complete digestion of cells due to action of hydrolytic enzymes
Liquefactive necrosis
Necrosis change can be seen Gross and microscopically
T or F
T
Necrosis:
The affected organ appears like boiled material
Coagulative necrosis
Necrosis:
Affected organ appears liquidy, creamy yellow because of pus
Liquefactive Necrosis
Coagulative necrosis is due to the sudden cut-off of?
Blood supply
Coagulative necrosis:
The action of hydrolytic enzyme is Free
T or F
F
Blocked not free
The action of Liquefactive necrosis of hydrolytic enzymes is not blocked
T or F
T
Necrosis:
Combination of Coagulative and Liquefactive
Caseous
Caseous necrosis is seen in what disease?
TB
The affected organ appears cheese (Soft and greesy)
Caseous
Necrosis:
Seen in acute pancreatitis, damage in fat cells
Fat Necrosis
Necrosis:
appears like chalky white precipitates
Fat necrosis
Type of necrosis seen in immune reactions involving blood vessels
Fibrinoid necrosis
Necrosis:
Changes in cells are too small to see grossly which is usually seen microscopically
Fibrinoid necrosis
Apoptosis is a normal physiological function in the body
