Module 4 Flashcards
(22 cards)
Necrosis
Pathological death of a tissue still a 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 blood and/or other fluids to dependent portions of the body immediately before death
Agonal Moisture Changes
Edema: increase in the amount of moisture in the fluids and body cavities. Dehydration: decrease in the amount of moisture in the tissues and body cavities. Caused by a flow of fluids to lower locations.
Translocation
Agonal or postmortem redistribution of host micoflora on a host-wide basis
Tissue Gas
Postmortem accumulation of gs in tissues or cavities vrought about by an anaerobic gas-forming bacillus, Clostirium perfringens
Algor Mortis
Postmortem cooling of the body to the surrounding temperature
Hypostasis
Settling of blood and/or other fluids to dependent portions of the body
Viscosity
Resistance to the flow of a liquid. Thickness of a liquid
Livor Mortis (Cadaveric Lividity)
Postmortem intravascular red-blue discoloration resulting from hypostasis of blood
Dehydration
Loss of moisture from body tissue that may occur antemortem (febrile disease, diarrhea, or emesis) or 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 red blood cells, seeps through the vessel walls and into the body tissues
Rigor Mortis
Postmortem stiffening of the body muscles by natural body processes
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 the 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-slip)
Sloughing of of the epidermis, wherein there is a separation of the epidermis from the underlying dermis
