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
The settling of blood into the dependent tissues of the body.
Agonal moisture changes
An increase or decrease in the amount of moisture, or fluids, in the tissues and the body cavities.
Translocation
Agonal or postmortem redistribution of host microflora on a hostwide 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 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 (livor mortis).
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 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 off of the epidermis, wherein there is a separation of the epidermis from the underlying dermis.
