Check out our essay example on Knee Injury Case Study to start writing! cell is the cell type most important for scar formation. , glucose);. Cell response to injury is not an all-or-nothing phenomenon: The stronger and the longer the stimulus, the larger the damage Response to a given stimulus depends on the type, status, and genetic make-up of the injured cell: Contrast ischemia in skeletal muscle (tolerates 2 hours) versus cardiac muscle (tolerate 20. Types of Low Temperature Injury. Degeneration is reversible but may progress to necrosis if injury persists. Hypertrophy is an increase in the size of an organ or tissue due to an increase in the size of cells. face and hands are the most common sites of injury, followed by respiratory damage, with eye damage being the least common injury (3). Radiation burns are caused by exposure to radiation. Trauma will often increase ALT activity, even without morphologic evidence of cell injury. Symptoms of nerve injury may be intermittent, if the injury repeats itself; or they may be constant, if the injury is severe enough. Even though many issues regarding the ethics of stem cell research have now been solved, it serves as a valuable example of ethical cost-benefit analysis. She will receive the award at the 2020 Annual Scientific meeting in New Orleans, May 2-6. Prior to the return of the alveolar epithelium to normal, cells have been identified that exhibit both ATII.
