Cell Injury & Adaptation

Hyperplasia generally means:

• An organ will increase in size due to excessive formation of extracellular fluids

• Increased cell production in a normal tissue

• Shrinkage in cell size

• Blebbing at the periphery

Necrosis is

• Reversible

• Lack of oxygen to the tissue

• Not reversible

• Blebbing at the periphery

Programmed cell death is known as

• Cytolysis

• Apoptosis

• Necrosis

• Proptosis

Liquefactive necrosis is seen in

• Heart

• Brain

• Lung

• Spleen

Which of the following is the most common cause of cell injury

• Chemical injury

• Hypoxia

• Infections

• Immunologic and Autoimmune diseases

Deposition of calcium salts in tissues other than osteoid or enamel is called

• Pathologic Calcification

• Autolysis

• Apoptosis

• Necrosis

Necrosis which occurred secondary to vascular occlusion and affected lower extremities would most likely be called

• Gangrenous necrosis

• Coagulative necrosis

• Fibrinoid necrosis

• Caseous necrosis

Gas Gangrene is caused by which bacteria

• Gram positive anaerobic bacteria

• Gram negative anaerobic bacteria

• Gram positive aerobic bacteria

• Gram negative aerobic bacteria

Coagulative necrosis is found in which infection

• Tuberculosis

• Sarcoidosis

• Actinomycosis

• Candisiasis

Adaptive cell responses such as aplasia and atrophy are potentially reversible processes

• True

• False
