Consider the following statementI Experimental hypertension can be produced to stimulating sinoaortic nerveII Sino-aortic nerve normally stimulates vasomotor centre Of these statements
**Core Concept**
The sinoaortic baroreceptors play a crucial role in regulating blood pressure by detecting changes in arterial pressure and sending signals to the vasomotor center in the brainstem to modulate sympathetic and parasympathetic tone.
**Why the Correct Answer is Right**
Stimulation of the sinoaortic nerve leads to activation of the baroreceptors, which in turn send signals to the vasomotor center to increase parasympathetic tone and decrease sympathetic tone, resulting in vasodilation and a decrease in blood pressure. This is the normal physiological response to increased blood pressure. However, if the sinoaortic nerve is stimulated experimentally to produce hypertension, it suggests that the baroreceptors are being overridden, and the body is unable to appropriately respond to the increased blood pressure.

**Clinical Pearl / High-Yield Fact**
The sinoaortic baroreceptors are sensitive to changes in arterial pressure and play a crucial role in regulating blood pressure. Damage to these receptors can lead to uncontrolled hypertension.
**Correct Answer: C.**
