Question

Quizplus · Accepted Answer

The pelvic nerves leave the sacral plexus on each side of the cord and distribute their peripheral fibers to the bladder, uterus, urethra, prostate, distal portion of the transverse colon, descending colon, and rectum. Sacral parasympathetic fibers also supply the venous outflow from the external genitalia to facilitate erectile function. The hypothalamus, vagus nerve, and postganglionic sympathetic neurons do not control erectile function.
