Question 1

What is the universal response to all tissue damage

Answer 1

Inflammation

Question 2

In the presence of acute inflammation what are the 3 pathways cells can go down

Answer 2

The cells can regrow pathway, this results in regeneration of the damaged cells entirely restoring all previous function

The cell cannot regrow pathway, this results in healing by repair, a scar is formed to seal the wound and the specialised function the cell previously had has been lost

the damage persists pathway, this results in chronic inflammation that will persist if the damaging agent is not overcome.
if the damaging agent is overcome then a scar will form as the damage is more severe

Question 3

What are the 3 main stages of inflammation

Answer 3

Vascular dilation

endothelial activation

neutrophil activation and migration

Question 4

What acts on the blood vessels to signal damage has been done

Answer 4

Histamines/ tissue mast cells
