Flashcards in 2nd QUARTER- EMBALMING Exam 2 Deck (53):
Irreversible cessation (a stop, pause, or interruption, especially a permanent discontinuation) of all vital functions.
Such as: respiration - breathing
heart action - circulation
brain action - waves
non legal definition of death
the noise made by a moribund (dying) person caused by air passing through a residue of mucous in the trachea and posterior oral cavity
time immediately preceding death
the semi-convulsive twitches which often occur before death.
conditions in which the manifestations of life are feebly maintained. (think the person is dead, coma state)
Respiration, heart action, brain action are shallow and sometime hard to detect.
body of a deceased person including cremated remains
those elements remaining after cremation of a dead human body.
dead human body used for medical purposes, including anatomical dissection and study.
the study of death
death of an organism (body) as a whole. Pronouncement of death. Historically it is recognized by the failure of one of three organs. (heart, brain, lungs)
death of the heart
death of the brain
death of the lungs
Death of the individual cells of the body
post mortem cellular death
Final cause of post mortem cellular death is
Post mortem cellular death will occur _____ somatic death
Somatic death will occur ______ or _______to post morten cellular death.
before or prior
Factors influencing onset of postmortem cellular death
Cause of death
Environmental conditions – temperature can be a factor, coolers help slow down decomposition
Condition of Body
Medication preceding death – meds can alter body chemistry
death occurring in a living body
Can cellular death occur anti-mortem?
these cells will die quicker after somatic death.
Brain cells live about
5 to 8 minutes
muscle cells live about
cornea and blood cells live about
6 to 8 hours
The major element remaining after cremation is?
Those manifestations of death by which we may recognize its presence in the body.
signs of death
the separation of compounds into simpler substances by the action of microbial and/or autolytic enzymes.
self destruction of body compounds.
most reliable sign of death
the stopping of blood flowing through the body.
cessation of circulation
the stopping of breathing
cessation of respiration
Post mortem cooling of the body to the surrounding temperature.
Also referred to as CADAVERIC lividity. The post mortem, intravascular, red-blue discoloration resulting from the hypostasis of blood.
inside the vessels
the gravitation of the blood into the lower part of the body.
Can livor mortis be removed with normal arterial injection and venous drainage?
Yes or No? Why?
Yes, because it is intravascular
the post mortem temporary stiffening of the body muscles due to natural chemicals the body process.
At death the muscles do not function. O sign and Q sign – reflecting muscle relaxation.
complete muscular relaxation
name the changes of the eye in regards to the signs of death
Clouding of the cornea and loss of luster.
Flattening of the eyeball.
Pupil does not respond to light.
Any procedure used to prove a sign of death.
test for death
how many expert tests are there for death
What are the four expert tests used for death?
a) Stethoscope -
b) Ophthalmoscope -
c) Electronic life detection devices
EKG – Electrocardiogram –
EEG – Encephalogram –
ABR – auditory brainstem response –
d) Injection of various dyes into the body to check for circulation -
a delicate instrument used to detect almost inaudible sounds produced in the body.
an optical instrument with an accompanying light that makes it possible to examine the retina and explore blood circulation in the eyes.
check for heart activity
check for brain wave activity.
checks for brain response responsible for vital acts of breathing and pulse.
ABR- audiroty brainstem response
an expert test for test injects dye in the the body...
2 cc of _______ is injected in the ________ _____
If there is circulation what happens?
the whites of the eyes turn green
how many inexpert tests for death are there?
Name the three inexpert test for death
ammonia injection test
feel for the pulse
ligate a finger; if it becomes discolored and swells, life is present.
hypodermically inject ammonia, if alive, the skin will show a reddish reaction
ammonia injection test
