Question
Terminology:
1. [blank_start]aetiology[blank_end]: cause of disease
2. [blank_start]pathogenesis[blank_end]: the mechanism of how disease develops
3. [blank_start]morphological changes[blank_end]: structural changes in tissues and organs
4. [blank_start]clinical significance[blank_end]: functional consequences
5. [blank_start]antemortem[blank_end]: before death
6. [blank_start]postmortem[blank_end]: after death
7. [blank_start]anatomical pathology[blank_end]: postmortem and tissue biopsy
8. [blank_start]gross pathology[blank_end]: postmortem with naked eye

Question 2
Question
ATP depletion is caused by [blank_start]hypoxia[blank_end] resulting in [blank_start]decreased[blank_end] oxidative posphorylation, [blank_start]decreased[blank_end] ATP, [blank_start]increased[blank_end] anaerobic glycolysis, [blank_start]decreased[blank_end] glycogen and decreased pH. the sodium potassium pump fails and ribosomes [blank_start]detach from[blank_end] the RER.

Question 3
Question
the three main causes of membrane damage are:
1. [blank_start]free radicals[blank_end] that cause lipid peroxidation
2. [blank_start]direct damage[blank_end] from chemicals, viruses etc.
3. [blank_start]Hypoxia[blank_end] resulting in ATP depletion.
Answer
-
free radicals
-
direct damage
-
Hypoxia
Question 4
Question
the most reactive oxygen species are [blank_start]superoxide[blank_end], [blank_start]hydrogen peroxide[blank_end] and [blank_start]hydroxyl radical[blank_end].
Answer
-
superoxide
-
hydrogen peroxide
-
hydroxyl radical
Question 5
Question
which of the following are sources of free radicals?
Answer
-
by-products of oxidative metabolism
-
phagocytic cells
-
metals
-
organophosphates
-
reperfusion following necrosis
-
reperfusion following ischaemia
-
radiation and UV light
-
drug and chemical exposure
-
nitric oxide.
Question 6
Question
free radicals injure cells via:
1. [blank_start]lipid peroxidation[blank_end] leading to extensive membrane damage
2. [blank_start]DNA damage[blank_end] which causes sing strand breaks
3. [blank_start]protein damage[blank_end] which causes the oxidation of amino acids
Answer
-
lipid peroxidation
-
DNA damage
-
protein damage
Question 7
Question
two patterns of reversible cell injury include:
1. [blank_start]hydropic degeneration[blank_end]: acute cell swelling due to fluid influx

Answer
-
hydropic degeneration
-
fatty change
