← Human Body & HealthWhat distinguishes arterial baroreceptor response in hypertension compared to normotension?
A)Increased parasympathetic nerve stimulation
B)Reduced sensitivity to blood pressure changes✓
C)Enhanced afferent signaling to brainstem
D)Greater inhibition of sympathetic activity
💡 Explanation
Arterial baroreceptors in hypertension exhibit decreased sensitivity because chronic high blood pressure resets their operating range, therefore they respond less effectively to changes in blood pressure, rather than exhibiting increased afferent signaling or enhanced sympathetic inhibition.
