Rates of firing from the baroreceptors represent blood pressure, level of physical activity, and the relative distribution of blood.
22.
The end-result of baroreceptor activation is inhibition of the sympathetic nervous system and activation of the parasympathetic nervous system.
23.
Generally, the baroreceptor reflex is not targeted in hypertension because if blocked, individuals may suffer from orthostatic hypotension and fainting.
24.
In people with essential hypertension the baroreceptors and their reflexes change and function to maintain the elevated blood pressure as if normal.
25.
Meanwhile, baroreceptors in the aortic arch detect the increase in blood pressure and trigger a parasympathetic response via the Vagus nerve.
26.
A competing theory involves compression of the baroreceptors of the carotid artery, confusing the body into thinking blood pressure has risen.
27.
The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse.
28.
The inhibition of the sodium pump may also improve baroreceptor sensitivity in HF and may explain some of the neurohormonal effects of digoxin.
29.
Baroreceptors are active even at normal blood pressures so that their activity informs the brain about both increases and decreases in blood pressure.
30.
The main limiting side-effects of alpha antagonists is that the baroreceptor reflex is disrupted and thus this can cause postural hypotension.
