Pathological morphology - inflammation Flashcards
Inflammation is
mostly sporadically occurring defence reaction of the body. Its aim is to reduce or remove the causative pathogenic factor and to restore the damaged tissue.
Main cell types at work during inflammation? (5)
Tissue macrophages,
monocytes,
mast cells,
platelets, and
endothelial cells
The Two main cytokines released first during inflammation in order to initaite inflammatory cascades
tissue necrosis factor-a (TNF-a) and interleukin (IL)–1
morphological characteristics of inflammation (3)
alteration
exudation
proliferation
clinical characteristics of inflammation (5)
dolor / pain
calor / heat
rubor / redness
tumor / swelling
function laesa / loss of function
First cycle of inflammatory reaction involves:
hyperemia,
stasis and
exudation,
diapedesis of granulocytes
In the event of inflammation with domination of hyperemia, results in
Congestive and hemorrhagic inflammation
In the event of inflammation with domination of exudation, results in
Exudative inflammation
In the event of inflammation with domination of granulocytic diapedesis, results in
Purulent inflammation
In the event of inflammation with domination of monoclear cell diapedesis, results in
granulomas and infiltrates
major cell of acute inflamamtion, phagocytic
neutrophil granulocyte
cell type to cause tissue injury
eosinophil granulocyte
when activated produces cytokines, chemokines, proteases and oxidative radicals
another name for mast cells
mastocyte
main cells of chronic inflammatory reactions
macrophages
what are plasma cells
Plasma cells develop from B lymphocytes.
There are two main types of B-cells: plasma cells and memory cells.
Normally, when bacteria or viruses enter the body, some of the B cells will change into plasma cells.
Plasma cells release antibodies in response to antigens.
