Cell Injury Flashcards
(28 cards)
Macroscopic deposition of calcium salts in injured tissues
Dystrophic calcification
Accumulation of cholesterol and cholesteryl esters in macrophages with arterial intima?
Atherosclerosis
Brown- black pigment found principally on epidermal cells of the skin
Melanin
Type of necrosis where the outline of the cell is maintained
Coagulative
Extrusion from the cell of a pkynotic nucleus
Karyolysis
The nucleus become smaller and stains deeply basophilic
Pkynosis
Removal of hydrogen atom from unsaturated fatty acids of membrane phospholipids
Lipid peroxidase
Enzyme responsible for conversion of hydrogen peroxide to hypochlorous acid
Myeloperoxidase
Mixture of lipids and proteins containing a golden brown pigment
Lipofuscin
Cavity filled with polymorphonuclear leukocyte
Abscess
Reversible increase in cell volume
Hydrophobic swelling
Principal cause of metastatic calcification
Deranged calcium metabolism
Proapoptotic molecule released by mitochondria
Cytochrome c
Cellular source of hypochlorous acid
Macrophages and neutrophils
Common analgesic that is highly toxic to the liver upon overdose
Acetaminophen
What enzyme doesn’t detoxify radical oxygen species
Telomerase
Molecule that preserves the viability of injured cells yet propels them towards apoptosis
P53
Type of myocardial necrosis
Coagulative necrosis
Storage of carbon particles in the lung and regional ln
Anthracosis
Type of necrosis caused by insudation of plasma proteins into the wall of injured blood vessels
Fibrinoid necrosis
Molecular component of alcoholic hyalin
Cytoskeletal filaments
Which of the following doesn’t cause hyperplasia?
Ischemia
Type of cell injury usually resulting from obstruction to the flow of blood
Ischemic cell injury
Cellular adaptation to diminishes need for more resources for cell’s activity
Atrophy
