The stages that follow shortly after death are: Corneal opacity or "clouding". Pallor mortis, paleness which happens in the first 15–120 minutes after death. 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.
Post-mortem phenomena to estimate the time of death. The post-mortem interval ( PMI) is the time that has elapsed since an individual's death. [1] When the time of death is not known, the interval may be estimated, and so an approximate time of death established. Postmortem interval estimations can range from hours, to days or even years ...
e. Rigor mortis [a] ( Latin: rigor "stiffness", and mortis "of death"), or postmortem rigidity, is the fourth stage of death. It is one of the recognizable signs of death, characterized by stiffening of the limbs of the corpse caused by chemical changes in the muscles postmortem (mainly calcium). [1] In humans, rigor mortis can occur as soon as ...
Livor mortis (Latin: līvor – "bluish color, bruise", mortis – "of death"), postmortem lividity (Latin: post mortem – "after death", lividitas – "black and blueness"), hypostasis (Greek: ὑπό, hypo, meaning "under, beneath"; στάσις, stasis, meaning "a standing") or suggillation, is the second stage of death and one of the signs ...
Thanatology. Thanatology is the scientific study of death and the losses brought about as a result. It investigates the mechanisms and forensic aspects of death, such as bodily changes that accompany death and the postmortem period, as well as wider psychological and social aspects related to death.
Death is the end of life; the irreversible cessation of all biological functions that sustain a living organism. [1] The remains of a former organism normally begin to decompose shortly after death. [2] Death eventually and inevitably occurs in all organisms.
Time of occurrence. In forensic investigation, the time of occurrence of an event (such as time of death, time of incident) is one of the most important things to determine accurately as soon as possible. Sometimes this can only be estimated. [1] Some indicators that investigators use are rigor mortis, livor mortis, algor mortis, clouding of ...
t. e. Timeline of postmortem changes, with algor mortis represented by red temperature line. 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. This is generally a steady decline, although if the ambient temperature ...
