In a patient experiencing hypertension, what distinguishes the arterial baroreceptor response to a sudden drop in blood pressure compared to a healthy individual?

A)Increased sensitivity to pressure changes
B)Greater activation of sympathetic outflow
C)Enhanced parasympathetic nervous system response
D)Reduced baroreceptor firing due to arterial stiffness

💡 Explanation

Arterial stiffness reduces the vessel's ability to deform in response to pressure changes, therefore the baroreceptors embedded in the vessel walls experience less stimulation. Because of reduced baroreceptor firing, compensatory mechanisms are blunted, rather than enhanced as in a healthy individual.
