Question

Increase in carotid sinus causes peripheral arterioles is due to

In response to an increase in carotid sinus pressure, peripheral arterioles dilate primarily due to: a. local dilatory agents, such as lactic acid and CO2 b. ed activity of sympathetic vasodilator fibers c. ed activity of parasympathetic vasodilator fibers. d. ed activity of sympathetic vasoconstrictor fibers e. ed stimulation of alpha-adrenergic receptors.

Answer 1

Option C is the correct one as in response to an increase in carotid sinus pressure, peripheral arterioles dilate primarily due to increased activity of the parasympathetic vasoconstrictor fibers, incraesing the cardiac output and thus decrease the blood pressure.
