The loss of moisture immediately before death.
Escape of blood serum from an intravascular to an extravascular location immediately before death.
Increase in body temperature immediately before death.
Redistribution of endemic microflora on a host-wide basis immediately before death.
Postmortem cooling of the body to the ambient temperature.
Characterized by the absence of free oxygen.
A condition in which the manifestations of life are feebly maintained.
Death beginning in the lungs due to an insufficient intake of oxygen.
Self-destruction of cells; decomposition of all tissues by enzymes of their own formation without microbial assistance.
The body's own digestive enzymes that are capable of destroying body cells.
Irreversible somatic death.
A dead body used for medical purposes.
Cadaveric spasm (Instantaneous rigor)
Immediate stiffening of the muscles of a dead human body.
Death of the individual cells of the body.
A phase of somatic death lasting from 5-6 minutes in which life may be restored.
Death beginning at the brain due to irreversible cessation of brain activity and loss of consciousness.
The legal term for a dead body.
Irreversible cessation of all vital functions.
Noise made by a moribund person caused by air passing through a residue of mucous in the trachea and posterior oral cavity.
The semi-convulsive twitches that often occur before death.
Decomposition of proteins by enzymes of aerobic bacteria.
Separation of compounds into simpler substances by the action of microbial and/or autolytic enzymes.
Loss of moisture from body tissue which may occur antemortem or postmortem; the removal of water from a substance.
Extreme dehydration often resulting in post-embalming discolorations.
Desquamation (Skin slip)
Separation of the epidermis from the underlying dermis as a result of putrefaction.
Outside the blood vascular system.
From outside the body.
The microbial (enzymatic) decomposition of carbohydrates under anaerobic conditions.
Destruction of red blood cells that releases heme.
The body (in whole or in part) of a deceased person, including cremated remains.
Decomposition with water as one of the reactants.
Process of blood and/or other fluids settling to the dependent portions of the body; can occur in the antemortem, agonal, or postmortem periods.
In articulo mortis
The movement of blood from the heart and arteries into the capillaries and veins, which occurs at the moment of death.
Within the blood vascular system.
From within the body.
Decomposition of fats.
Livor mortis (Cadaveric lividity)
Intravascular, red-blue discoloration resulting from postmortem hypostasis of blood.
Manipulation of tissue in the course of preparation of the body.
In a dying state; in the agonal period.
Antemortem, physiological death of the cells of the body followed by their replacement.
Pathological death of a tissue still a part of the living organism.
The rise in body temperature after death due to continued cellular metabolism.
Postmortem chemical change
Change in the body's chemical composition that occurs after death.
Postmortem physical change
Forces of nature that act on the body to alter the physical state of the body or tissues after death.
Extravascular color change that occurs when heme seeps through the vessel walls and into the body tissues.
Decomposition of proteins.
Any one of a group of nitrogenous organic compounds formed by the action of putrefactive bacteria on proteins; indole, skatole, cadaverine, and putrescine.
Decomposition of proteins by the action of enzymes from anaerobic bacteria.
Postmortem stiffening of the body muscles by natural body process.
Decomposition of sugars.
Death of the organism as a whole.
Death beginning at the heart.
The thickness of a liquid.
