  DEATH. The Columbia Encyclopedia: Sixth Edition. 2000   (Site not responding. Last check: 2007-11-03)
Death may involve the organism as a whole (somatic death) or may be confined to cells and tissues within the organism.
Somatic death is characterized by the discontinuance of cardiac activity and respiration, and eventually leads to the death of all body cells from lack of oxygen, although for approximately six minutes after somatic death—a period referred to as clinical death—a person whose vital organs have not been damaged may be revived.
Somatic death is followed by a number of irreversible changes that are of legal importance, especially in estimating the time of death.

 Death and Dying - MSN Encarta
Somatic death is the death of the organism as a whole; it usually precedes the death of the individual organs, cells, and parts of cells.
Somatic death is marked by cessation of heartbeat, respiration, movement, reflexes, and brain activity.
The precise time of somatic death is sometimes difficult to determine, however, because the symptoms of such transient states as coma, faint (see Fainting), and trance closely resemble the signs of death.

Traditionally, death has been defined by clinicians as the permanent cessation of the heartbeat and respiration (somatic death).
When brain death is diagnosed, cessation of life support measures, (sometimes after organ harvesting for transplantation) is usually carried out, and somatic death promptly follows.
Although the diagnosis of brain death is a clinical one, from time to time the clinician may seek guidance from a variety of ancillary tests.

 Pleasure, Perversion and Death 3.2 Regression and Aggression
Although they are corporal death drives and therefore refer to my argument, aggression and regression represent the re-gressive and a-ggressive externalized drive for a transformed flesh that continues the nihilism of the perfectly-formed male subject and psychoanalytic theorist.
It is the death drive that in and through the figure of the tyrant to be killed, and the primary narcissistic representative to be destroyed, defines the place of the unconscious representatives as both one’s native land of exile and lost paradise to be regained.
Death in its representation unnerves the subject and hence it is from here that it shall be used as a means to begin the processual transforming (but never transformed) self.

Mutations are permanent, transmissible changes to the genetic material (usually DNA or RNA) of a cell, and can be caused by: "copying errors" in the genetic material during cell division; by exposure to radiation, chemicals, or viruses.
In multicellular organisms, mutations can be subdivided into germline mutations that occur in the gametes and thus can be passed on to progeny, and somatic mutations that often lead to the malfunction or death of a cell and can cause cancer.

 T. H. Huxley: The Evidence of the Miracle of the Resurrection
There is a broad distinction to be drawn between somatic death or the cessation of the obvious functions of the living body, which result from the activities of the molecules living of the body–and molecular death, which is the cessation of those activities.
Yet the molecular structure of the living matter remains; the works of the watch are, so to speak, jammed by the withdrawal of something essential to their mobility, and when this substance, in the present instance water, is restored, they go on again.
And if it is not possible for us to say whether the body of Jesus underwent molecular death or not, it would be a mere futility to discuss the further question, whether he was miraculously resuscitated or not.
