Thanatology. Autopsy (1890) by Enrique Simonet. 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.
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.
Manner of death. In many legal jurisdictions, the manner of death is a determination, typically made by the coroner, medical examiner, police, or similar officials, and recorded as a vital statistic. Within the United States and the United Kingdom, a distinction is made between the cause of death, which is a specific disease or injury, versus ...
Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized : apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to characteristic cell changes ( morphology) and death. [2]
Programmed cell death ( PCD; sometimes referred to as cellular suicide [1]) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. [2] [3] PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle. For example, the differentiation of fingers and toes in a ...
Apoptosis is the programmed cell death of superfluous or potentially harmful cells in the body. It is an energy-dependent process mediated by proteolytic enzymes called caspases, which trigger cell death through the cleaving of specific proteins in the cytoplasm and nucleus. The dying cells shrink and condense into apoptotic bodies.
Cell death. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Necrosis (from Ancient Greek νέκρωσης (nékrōsis) 'death') is a form of cell injury which results in the premature death of cells in living tissue by autolysis. [1] The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow, who is often regarded as one of the founders of ...
