L3. Inflammation and Repair

What are the two types of cell death mentioned in the text?

• Apoptosis and Pyknosis

• Necrosis and Karyolysis

• Necrosis and Apoptosis

• Pyknosis and Gangrene

Which type of cell death is described as the death of body tissue due to injury, disease, or interruption of blood supply?

• Karyolysis

• Necrosis

• Apoptosis

• Pyknosis

What is the structural sign of severe necrosis mentioned in the text?

• Dense clamping

• Shrinkage of Cellular Contents

• Swelling of cell contents

• Formation of Apoptotic Bodies

Which type of cell death is an orderly process in which the cell's contents are packaged into small packets of membrane for 'garbage collection' by immune cells?

• Pyknosis

• Necrosis

• Apoptosis

• Karyolysis

What is the difference in cause and presentation between necrosis and apoptosis?

• Necrosis leads to tumor formation, while apoptosis leads to inflammation

• Necrosis causes imbalance in internal cell environment, while apoptosis removes cells during development

• Necrosis requires energy, while apoptosis is a random event

• Necrosis is a physiological process, while apoptosis is a pathological process

Which type of necrosis results in a transformation of the tissue into a liquid viscous mass?

• Fat

• Caseous

• Coagulative

• Liquefactive

What is the characteristic of dry gangrene?

• Result from hypoxia by ischemia and chemical injury

• Caused by Clostridium bacteria

• Occurs in internal organs causing site to become cold, swollen and black

• Skin becomes very dry and shrinks causing wrinkles

Which type of necrosis is a combination of coagulative and liquefactive necrosis?

• Coagulative

• Caseous

• Gangrenous

• Fat

What causes gas gangrene according to the text?

• Hypoxia by ischemia

• Digestive hydrolytic enzymes and lipids of the brain

• Bacterial infection with Clostridium

• Protein denaturation

What is the difference in biochemical reaction between necrosis and apoptosis?

• Necrosis requires many enzymes and agents, while apoptosis does not require energy

• Necrosis occurs in an organized manner, while apoptosis does not require energy

• Necrosis is an active process, while apoptosis is a passive process

• Necrosis is a random event, while apoptosis occurs in an organized manner
