Where are my Manners...of Death.
This is defined as either the irreversible cessation (stopping) of the circulation of blood: the heart stops beating OR the cessation of ALL brain activity
Death
Roughly defined as “death stiffness”
Rigor Mortis
The procedure of cutting open a body to determine information about its death
Autopsy
The study of insects that are associated with a dead body
Forensic Entomology
A body is found in the woods. Blowflies have just begun to find the body. The body temperature is only slightly lower than normal. Did this person die less than or more than 8 hours ago?
Less; approx 2 hours
True or False: A person who is considered brain dead can be considered dead
False
The cooling of the body following death
Algor Mortis
There are two REASONS for an autopsy to be performed, as well as two PHASES of each autopsy performed. They are:
Reasons: Clinical; Forensic
Phases: External; Internal
Entomological evidence is the most useful after this amount of time has passed
72 hours
A body is found in the woods. Their entire body is rigid. There is permanent lividity on their back from where they've been lying. Did this person die less than or more than 8 hours ago?
More; approx 12 hours
These are the four manners of death:
Natural, Accidental, Suicidal, Homicidal
The result of a “death color” when blood cells and blood vessels decompose
Livor Mortis
The contents of a corpse's digestive system can give us information on what:
This source of entomological evidence is used when death has occurred within a month
Blowfly larva development
A body is found in the woods. Upon an autopsy, it is discovered that this person had food still digesting in their small intestines. How long after their last meal was this person killed?
12 hours
This event after dead begins once the heart stops beating and the circulation of blood can no longer continue, oxygen can no longer be taken to the cells of the body
Stoppage
The reddish-purple coloration of a body following the pooling of blood
Lividity
The phase of decomposition between a week and a month since the body has been dead, resulting in the strongest odor of the body is known as what stage
Active Decay or Black Putrefaction
This source of entomological evidence is used when death has occurred between a month and year
Carrion Insect Succession
A body is found in the woods. All along the body, dark brown blowfly pupa can be found. The body has a very strong odor. Has this body been dead more or less than a month?
Less; about 24 days
When cells trigger a process of demolition, where cellular enzymes breakdown and destroy each of the cells
Autolysis
This refers to the established time between death and bodily discovery
The Post Mortem Interval (PMI)
The lower limit threshold, or the temperature at which growth/development cease, is equal to these two temperatures:
10℃ and 50℉
A body is found in the woods. Most of the flesh on the body is gone. Hairy Rove beetles crawl all over the body. Did this person die less than or more than a month ago?
More
What is the meaning of "proximate cause"?
It refers to an underlying cause of death; in other words, a factor that contributed, but was not the final cause of death
By this amount of time passing, all three mortis phases have completed their cycle
48 hours
The mortises take place during these TWO phases of decomposition
What are Fresh (initial) and Bloating (Putrefaction)
A body is found at 12 pm. The high temp of the day was 40℃, the low was 20℃. Calculate the ADH
(40+20)/2 = 30℃
30℃ - 10℃ = 20℃
20℃ x 12 = 120 thermal units
A body is found in the woods. Its body temperature is 76.1℉. If the normal body temp is 98.6℉, and a body cools at a rate of 1.7℉/hour or the first 12 hours, and 0.7℉/hour every hour following, how long as this body been dead EXACTLY?
15 hours
