Module 4 Flashcards
Necrosis
Pathological death of a tissue still part of the living organism
Necrobiosis
Antemortem, physiological death of the cells of the body followed by their replacement
Agonal Algor
Decrease in body temperature immediately before death
Agonal Fever
Increase in body temperature immediately before death
Agonal Hypostasis
Settling of the blood and/or other fluids to the dependent portions of the body that occurs immediately before death.
Agonal moisture changes
loss of moisture from body tissue during the agonal stage
Translocation
Agonal or postmortem redistribution of host microflora on a host wide basis
Tissue Gas
Postmortem accumulation of gas in tissues or cavities brought about by an anaerobic gas forming bacillus, Clostridium perfringens
Algor Mortis
Postmortem cooling of the body to the surrounding temperature
Hypostasis
Settling of blood and or other fluids to dependant portions of the body
Viscosity
Resistance to the flow of a liquid. Thickness of a liquid
Livor Mortis
Postmortem intravascular red-blue discoloration resulting from hypostasis of blood
Dehydration
Loss of moisture from body tissue that may occur antemortem or postmortem (antemortem: febrile disease, diarrhea, or emesis; postmortem: injection of embalming solution or through absorption by the air.)
Postmortem caloricity
Rise in body temperature after death due to continued cellular metabolism
Postmortem stain
Extravascular color change that occurs when heme, released by hemolysis of blood cells, seeps through the vessel walls and into the body tissues
Rigor Mortis
Postmortem stiffening of the body muscles by natural body process
Autolysis
Self-destruction of cells. Decomposition of all tissues by enzymes that form without microbial assistance
Hydrolysis
Reaction in which water is one of the reactants and compounds are often broken down. In hydrolysis of proteins the addition of water accompanied by the action of enzymes results in the breakdown of protein into amino acids
Proteolysis
Decomposition of proteins
Putrefaction
Decomposition of proteins by the action of enzymes from anaerobic bacteria
Decay
Decomposition of proteins by enzymes of aerobic bacteria
Desquamation
(skin flip) sloughing off of the epidermis, wherein there is separation of the epidermis from the underlying dermis
