Question

True or False: The parasympathetic nervous system controls both erection and contraction of the smooth muscle in the seminal vesicle.

Answer 1

The answer is false.

You can remember this by the saying "point" and "shoot"

Parasympathetic "Point" - is responsible for the erection: NO → (+) guanylyl cyclase → ↑ cGMP → smooth muscle relaxation and vasodilation

Sympathetic "Shoot" - is responsible for emission, which is facilitated by the peristaltic contractions of the vas deferens, prostatic smooth muslces and of course SEMINAL VESICLES (only in caps to show the answer, not shouting at you)

One step further is the ejaculation is controlled by the somatic muscles with rhythmic contraction of the perineal muscles.

I hope this helps, do not hesitate to follow-up if needed.
