Which statement regarding sympathetic stimulation effects on blood pressure is incorrect?

Question

Quizplus · Accepted Answer

Sympathetic stimulation typically causes an increase in both total peripheral resistance and cardiac output. This is due to vasoconstriction of arterioles (answer A) and increased stroke volume (answer C), respectively. Vasoconstriction of veins (answer D) can also increase venous return, but this does not necessarily lead to an increase in blood pressure. Additionally, vasoconstriction of veins (answer E) may increase preload and therefore enhance stroke volume, but this does not directly impact blood pressure. Option B is incorrect because decreased end diastolic volume (i.e. decreased preload) would actually decrease cardiac output, not increase it.
