Livor mortis, or dependent lividity, a settling of the blood in the lower (dependent) portion of the body; Algor mortis, the reduction in body temperature following death. This is generally a steady decline until matching ambient temperature; Rigor mortis, the limbs of the corpse become stiff (Latin rigor) and difficult to move or manipulate
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 ...
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 ...
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).

A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
Cadaveric spasm can be distinguished from rigor mortis as the former is a stronger stiffening of the muscles that cannot be easily undone, while rigor mortis can. [ 2 ] The cause is unknown but is usually associated with violent deaths under extreme physical circumstances with intense emotion , such as the circumstances associated with death ...
Algor mortis, the reduction in body temperature following death. This is generally a steady decline until matching ambient temperature; Rigor mortis, the limbs of the corpse become stiff (Latin rigor) and difficult to move or manipulate; Livor mortis, a settling of the blood in the lower (dependent) portion of the body
Somatic death is the cessation of the tripod of life, meaning the failure of circulation, respiration, or cerebral activity. Cellular death continues long after somatic death, with the classic resulting condition of rigor mortis (stiffening of the muscles due to lack of oxygen and increase in lactic acids). Postmortem changes are also ...
