Do you know what is a cell injury? Check your knowledge of general pathology by answering these MCQs asked in this quiz. Did you know that our cells can also become injured, like bones, muscles, and skin? A cell can suffer various stress changes due to extreme environmental changes, including internal and external both. The below quiz will help you see how much you know about the mechanism of cellular injury. Also, it will evaluate your understanding and give you some extra knowledge regarding cell damage.
