As mean arterial pressure increases, the ________, informing the medulla oblongata that blood pressure has indeed increased.

finlep [7]

As mean arterial pressure increases, the frequency of action potentials from the baroreceptors increases, informing the medulla oblongata that blood pressure has indeed increased.

Special receptors called baroreceptors monitor variations in your blood pressure.
The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
The brain interprets the information that the baroreceptors send as a rise in blood pressure.
The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.
