Question 1

Necrosis

Answer 1

Pathological death of a tissue still a part of the living organism.

Question 2

Necrobiosis

Answer 2

Antemortem, physiological death of the cells of the body followed by their replacement.

Question 3

Agonal Algor

Answer 3

Decrease in body temperature immediately before death.

Question 4

Agonal Fever

Answer 4

Increase in body temperature immediately before death.

Question 5

Agonal Hypostasis

Answer 5

The settling of blood into the dependent tissues of the body.

Question 6

Agonal moisture changes

Answer 6

An increase or decrease in the amount of moisture, or fluids, in the tissues and the body cavities.

Question 7

Translocation

Answer 7

Agonal or postmortem redistribution of host microflora on a hostwide basis.

Question 8

Tissue Gas

Answer 8

Postmortem accumulation of gas in tissues or cavities brought about by an anaerobic gas forming bacillus, Clostridium perfringens.

Question 9

Algor Mortis

Answer 9

Postmortem cooling of the body to the surrounding temperature.

Question 10

Hypostasis

Answer 10

Settling of blood and/or other fluids to dependent portions of the body.

Question 11

Viscosity

Answer 11

Resistance to the flow of a liquid. Thickness of a liquid.

Question 12

Livor Mortis (Cadaveric lividity)

Answer 12

Postmortem intravascular red-blue discoloration resulting from hypostasis of blood (livor mortis).

Question 13

Dehydration

Answer 13

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).

Question 14

Postmortem caloricity

Answer 14

Rise in body temperature after death due to continued cellular metabolism.

Question 15

Postmortem stain

Answer 15

Extravascular color change that occurs when heme, released by hemolysis of red blood cells, seeps through the vessel walls and into the body tissues.

Question 16

Rigor Mortis

Answer 16

Postmortem stiffening of the body muscles by natural body processes.

Question 17

Autolysis

Answer 17

Self-destruction of cells. Decomposition of all tissues by enzymes that form without microbial assistance.

Question 18

Hydrolysis

Answer 18

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.

Question 19

Proteolysis

Answer 19

Decomposition of proteins.

Question 20

Putrefaction

Answer 20

Decomposition of proteins by the action of enzymes from anaerobic bacteria.

Question 21

Decay

Answer 21

Decomposition of proteins by enzymes of aerobic bacteria.

Question 22

Desquamation (skin-slip)

Answer 22

Sloughing off of the epidermis, wherein there is a separation of the epidermis from the underlying dermis.
