apparent death | when the heart beat, respiration, body temp, and other vital functions are feebly maintained. |
death rattle | a sound sometimes made by the dying caused by labored breathing of air passing through bronchial mucus |

agonal period | the time immediately before death |
moribund | in a dying state during the agonal period |
what are the final words of one who is dying called | in articulo mortis "at the edge" |
cadaver | a dead human body embalmed in a specific way for the purpose of anatomical dissection |
the elements left over after the cremation of a human body are known as | cremains |
mortality rate | the ratio of a number of deaths over a given peroid of time within a specific population |
morbidity rate | the ratio of a number of specific diseases over a given peroid of time within a specific population |
the word _____ should never be used when talking about cremated human reamins | ashes; it's unprofessional! |
somatic death | death of the whole organism, the breakdown of all intra body coordination |
the first stage of death whereby there is a cessation of heart beat and respiratin for up to 5 mins. during which time life may be restored | clinical death |
biologic death | irrevocable or irreversible death and occurs after clinical death, this is legal death |
who came up with the tripod of life? | Bichat |
what organs are included in the tripod of life | heart, lungs, brain |
syncope | when the heart is the first to go |
coma | when the brain is the first to go |
asphyxia | when the lungs are the first to go |
cellular death | follows somatic death, aka anoxia or death of individual cells |
hypoxia | reduction of oxygen |
molecular | decomp will follow |
necrobiosis | anti-mortum of cells and their replacement by new, most frequently skin and red blood cells, this is normal |
necrosis | pathological death of certain cells in a living body and not a natural process such as bed sores |
signs of death | those sensable manifestations that indicate the adsences of life in the human body |
a person must meet 2 or more of the signs of death in order to confirm death, T/F | true, because some medical conditions can resemble most of the signs |
The ONLY sign of death that does not need another sign to varify | general decomp |
cessation of heart beat, respiration & blood flow stopped for 5 mins. presumpted evidence of death | one sign of death |
Algor Mortis | post mortum adjustment of body temp to that of surrounding environment |
Rigor Mortis | post mortum rigidity or temporary stiffness of the voluntary and involuntary muscles as a result of chemical changes. |
Livor Mortis | lividity which is the settleing of the blood to the dependent party of the body clostest to the gravitation pull of the Earth. |
Dehydration | loss of moisture through the skin that causes hardness and darkening of the skin |
changes in the eyes include | cornia becomes cloudy/milky, eyeball softens and flattens can sink into back of socket, shine is gone leaving the eye dull |
what is the first sign of death that starts but the last to be seen | decomposition |
where is the first place decomp is noticeable | lower right quadrant |
tests for death | any procedure used to prove a sign of death |
what are the expert tests for death | stethoscope test, opthalomoscope test, dye injection test, electrocardiograph, and electrencephalograph test. |
what are the inexpert or common tests for death | heart beat/resp., pulse test, ligature test, ammonia injection test, and mirror test |
what are the PM chemical changes | Decomp, proteolysis, sacchrolysis, lipolysis, nutolysis |
what is proteolysis | decomp of proteins |
what is sacchrolysis | the breakdown of the sugars glucose and glycogen |
lipolysis | decomp of fats |
autolysis | self destruction of the cell |
lysosomes do what | digestion |
what are the two types of prteolysis | putrefaction and decay |
putrefaction | caused by enzymes, produces anaerobic bacteria and does not need O |
decay | produces aerobic bacteria and needs O |
fermentation | the breakdown of carbohydrates into organic acids by anaerobic bacteria |
gas disstention | gas build up |
adipocere is also known as | grave max |
when the body is in direct contract with alcohiline earth what process could occur | saponificatioin |
what are physical signs of decomp | change in skin color, odor, purge, skin slip (desquamation), gas collection |
what are intrinsic factors | within the body |
what are the intrinsic factors | age, gender, corpulenc (fat), cause of death, bacteria, moisture level in the tissues, thermal levels, drugs |
what is extrinsic factors | outside the body |
what are the extrisic factors | access to air, atmosphereic moisture, temp of the environment, bacteria, pressure due to clothing/earth |
what is the ideal temp for bacteria growth | 99.5F |
what is the first and last two organs to decompose | lining of the larynx & trachea and blood vessels and non-pregnant uterus |
what are the 3 stages of rigor | 1-primary flaccidity, 2-onset, duration & termination, 3-secondary flaccidity |
what is the equation for Casper's Law | 1:2:8 |
what does Casper's Law mean | a body at 1 week decomp in open air will display the same level of decomp as a body in water and a body buried in earth at 8 weeks will display the same level of decomp as the open air body at 1 week |
what does custus an serina mean or what is it | goose pimps, it's a sign a body is in rigor. the constriction of the folics will make the hair stand up |
rigor is also known as | cadaveric rigidity |
even though rigor is the most variable, about when does it sets in | 8-20 hours after death |
algor is also known as | pm caloricity |
what is the rate of heat loss | 4 degrees an hour for the 1st 4 hours, then 1.5 degrees an hour thereafter |
livor is also known as | pm lividity or cadaveric lividity or cadaveric ecchymosis or passive congestion and hypostatic congestion |
the 3 blood clots are | cruor, chicken fat clot and white fiber clot |
describe a cruor clot | jelly-like |
describe a chicken fat clot | white cells separate and clump together and sometimes form on top of the cruor clots |
describe a white fiber clot | the worst to remove, formed from the fiber of the blood and especially likes haging oyt in the right atrium. |
what factors may effect the onset, duration & termination rigor | age, cause of death, muscular condition |
what conditions may be mistaken for rigor | heat stiffening, cold stiffening, catalepsy, and cadaveric spasm |
