WebWhat are mechanisms of cell injury? These fundamental underlying biochemical mechanisms of cell injury are (1) ATP depletion, (2) permeabilization of cell membranes, (3) disruption of biochemical pathways, and (4) damage to DNA. These four mechanisms will be discussed in greater detail in later sections of this chapter. WebIf the contact time is brief, nonthermal mechanisms of cell damage will be most important and the damage is relatively restricted to the cell membrane. When contact time is much longer, however, heat damage predominates and the whole cell is affected directly. These parameters also determine the anatomic tissue distribution of injury. WebMechanisms of injury leading to cell degeneration and necrosis. Individual separate mechanisms are discussed in the text. Lethal Injury (Necrosis) Lethal injuries to the tissues of a living individual cause cell death (necrosis). Necrosis is accompanied by biochemical and structural changes (see below) and is irreversible. emma beddington wig
