Livor mortis (from Latin līvor 'bluish color, bruise' and mortis 'of death'), postmortem lividity (from Latin post mortem 'after death' and lividitas 'black and blueness'), hypostasis (from Greek ὑπό (hypo) 'under, beneath' and στάσις (stasis) 'a standing') [1] [2] or suggillation, is the second stage of death and one of the signs of ...
The size and development stage of maggots can be used to give a measure of the minimum time since death. [9]: 251–252 Insect activity occurs in a series of waves, and identifying the insects present can give additional information on the postmortem interval. [10] Adipocere, or corpse wax, may be formed, inhibiting further decomposition.
Algor mortis (from Latin algor 'coldness' and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched.
A substudy of gerontology known as biogerontology seeks to eliminate death by natural aging in humans, often through the application of natural processes found in certain organisms. [10] However, as humans do not have the means to apply this to themselves, they have to use other ways to reach the maximum lifespan for a human, often through ...
Rigor mortis: stiffening of limbs. Conditions at the scene of death affect the estimation of time of death. To algor mortis , livor mortis and rigor mortis , together with consideration of stomach contents, there needs to be some observation of environmental conditions at the death scene to accurately measure the PMI (Fig. 1).

Putrefaction is the fifth stage of death, following pallor mortis, livor mortis, algor mortis, and rigor mortis. This process references the breaking down of a body of an animal post-mortem . In broad terms, it can be viewed as the decomposition of proteins , and the eventual breakdown of the cohesiveness between tissues, and the liquefaction ...
A 2007 study found that about 90% of the genes in the Abyssinian domestic cat are similar to humans. ... Even bananas surprisingly still share about 60 percent of the same DNA as humans!
Examples of injuries incompatible with life are decapitation or gross dismemberment.Other circumstances that are regarded as self-evidently incompatible with life include traumatic hemicorporectomy, decomposition, incineration, hypostasis and rigor mortis; in these circumstances, paramedics and other similar workers may be allowed to regard a person as dead in the absence of a physician.
