Q

What does the sympathetic chain do?

A

Rectum > decreases movement
Contracts internal anal and urethral sphincters
Relaxes bladder detrusor
Ejaculation = contract ductus deferens and seminal vesicle
Uterus= relax/ contract
Vasoconstriction of arteries

Q

What does the parasympathetic chain do?

A

Pelvic splanchnic nerves S2-4
Increase motility rectum and anal canal
Relax internal anal sphincter
Bladder = contracts detrusor and inhibits contraction of internal sphincter
No effect on seminal vesicles, ductus deferens, uterus

Vasodilation of arteries= erection
