Cell injury pathology

1. Cell Injury, Cell Death and Adaptation

2. Cell Injury Cell constantly faces internal external stresses, in responce either adapt or gets injured. Causes of cell injury given in fig:

3. Reversible Cell Injury A deranged of function and morphology that cell can recover from, if damage stimulus is removed.

4. Necrosis: cellular membrane fall apart,cellular enzyme leak out and digest the cell with inflammatory reaction.

5. Apoptosis: pathway of cell death, in which cell activate enzyme that degrade cell’s own nuclear DNA and Nuclear and cytoplasmic proteins.

6. Difference between Necrosis And Apoptosis:

7. Cellular Adaptation: Reversible changes in number , size, phenotype, metabolic activity, or functions of cells in responce to changes in their environment.
