Question

Quizplus · Accepted Answer

Erection is indeed the result of vascular spaces in the erectile tissues filling with blood. Expansion of the penile tissues results in compression of the venous outflow, rather than dilation as stated in option B. Option C is incorrect because parasympathetic impulses, not sympathetic, are responsible for causing penile arteriolar dilation resulting in erection. Ejaculation is indeed the result of sympathetic stimulation, not parasympathetic as stated in option D.
