Cell injury

Question 1

What is cell injury?

Answer 1

Cell injury refers to the damage caused to cells, which can lead to cell dysfunction or death.

Question 2

True or False: Cell injury can be reversible.

Answer 2

True

Question 3

Fill in the blank: The primary cause of cell injury can be classified as __________, __________, and __________.

Answer 3

hypoxia, physical agents, chemical agents

Question 4

What is hypoxia?

Answer 4

Hypoxia is a condition in which there is a deficiency of oxygen in the tissues.

Question 5

Name one physical agent that can cause cell injury.

Answer 5

Trauma

Question 6

What is apoptosis?

Answer 6

Apoptosis is a programmed cell death that occurs in a controlled manner.

Question 7

True or False: Necrosis is a form of programmed cell death.

Answer 7

False

Question 8

What are the morphological changes associated with necrosis?

Answer 8

Cell swelling, membrane rupture, and inflammation.

Question 9

Multiple Choice: Which of the following is NOT a type of necrosis? A) Coagulative B) Caseous C) Apoptotic D) Liquefactive

Answer 9

C) Apoptotic

Question 10

What is the main difference between necrosis and apoptosis?

Answer 10

Necrosis is uncontrolled cell death often due to injury, while apoptosis is a regulated process.

Question 11

Fill in the blank: __________ injury refers to damage caused by toxins.

Answer 11

Chemical

Question 12

What role does inflammation play in cell injury?

Answer 12

Inflammation can exacerbate cell injury and contribute to tissue damage.

Question 13

True or False: Reversible cell injury can lead to cell death if the damaging stimulus persists.

Answer 13

True

Question 14

What is the significance of the cell membrane in cell injury?

Answer 14

The cell membrane’s integrity is crucial for maintaining homeostasis and preventing cell injury.

Question 15

Multiple Choice: Which of the following is a feature of reversible cell injury? A) Cell swelling B) Membrane rupture C) Inflammation D) Tissue necrosis

Answer 15

A) Cell swelling

Question 16

What is ischemia?

Answer 16

Ischemia is a reduction in blood flow to a tissue, leading to a shortage of oxygen and nutrients.

Question 17

Fill in the blank: The __________ response is a common reaction to cell injury.

Answer 17

inflammatory

Question 18

What is the role of reactive oxygen species (ROS) in cell injury?

Answer 18

ROS can cause oxidative damage to cellular components, leading to cell injury.

Question 19

True or False: All cell injuries lead to necrosis.

Answer 19

False

Question 20

What is the term for the death of cells in a localized area due to lack of blood supply?

Answer 20

Infarction

Question 21

Multiple Choice: Which type of necrosis is characterized by cheese-like appearance? A) Coagulative B) Caseous C) Liquefactive D) Gangrenous

Answer 21

B) Caseous

Question 22

What is the primary consequence of irreversible cell injury?

Answer 22

Cell death

Question 23

Fill in the blank: __________ necrosis often occurs in brain tissue due to bacterial infection.

Answer 23

Liquefactive

Question 24

What is the difference between apoptosis and necrosis in terms of inflammation?

Answer 24

Apoptosis typically does not provoke an inflammatory response, while necrosis often does.

Question 25

True or False: Cellular adaptations can occur in response to chronic injury.

Answer 25

True
