Question 1

Which of the following best describes the cellular adaptation process known as hypertrophy?

Increase in the number of cells in a tissue

Decrease in cell size and tissue mass due to reduced functional demand

Question 2

A patient with a history of long-term immobilization due to a spinal injury is evaluated. Which cellular change is most likely observed in the patient’s unused leg muscles?

An increase in the number of cells in response to decreased neural stimulation

A decrease in the size of cells due to decreased workload

During the treatment of a heart attack, tissue plasminogen activator (tPA) is used to dissolve the blood clot causing ischemia. However, this reperfusion can lead to further tissue damage. Which of the following mechanisms primarily contributes to this ischemia-reperfusion injury?

Restoration of normal mitochondrial function immediately upon reperfusion

Increased extracellular calcium influx into compromised cells, leading to activation of calpain and cell death

Decreased recruitment of inflammatory cells, reducing the generation of reactive oxygen species
