THE MORPHOLOGY OF CELL AND TISSUE INJURY The relationship among cellular function, cell death, and the morphologic changes of cell injury. E.g. myocardial cells  noncontractile after 1 to 2 minutes of ischemia  dead after 2 to 3 hours by electron microscopy  by light microscopy for 6 to 12 hours
