Cellular Pathology and Mechanisms of Cell Injury Quiz

Carbon monoxide is an example of an exogenous toxin causing cell injury.

Hypertrophy is not a common mechanism of cell injury.

Direct toxic effects on cellular components are a common cause of cellular injury by chemical agents.

Direct mechanical disruption of cell structure is a common cause of cellular injury by physical agents.

Increased ATP production is not a cause of cellular injury.

Mitochondrial damage is not characteristic of reversible cell injury.

Mitochondria are primarily responsible for ROS production in a cell.

Apoptosis involves the orderly dismantling of cellular components.

Hypertrophy involves an increase in cell size in response to increased workload.

An inflammatory response is a characteristic feature of necrosis.

Caseous necrosis is characterized by a combination of coagulative and liquefactive necrosis.

Blebbing of plasma membrane is a characteristic feature of apoptosis.

Necrosis is associated with the release of cellular contents and triggers an inflammatory response.

Caseous necrosis is commonly seen in tuberculosis infection.

Atrophy involves a decrease in the size of cells.

Gangrenous necrosis is characterized by the presence of dead tissue and is typically caused by impaired blood supply.

Pyknosis of the nucleus is a hallmark feature of irreversible cell injury.

Decreased ATP production is the main cause of cell injury during hypoxic conditions.

Blebbing of plasma membrane is a common feature of apoptosis.

RNA is not a cellular target of reactive oxygen species (ROS).

Induction of apoptosis is not a function of autophagy.

Mitochondria are primarily affected in ischemia-induced cell injury.

Autophagy is a function of cellular recycling.

Mitochondria are primarily affected in reperfusion injury.
