39
Q

What is the venous drainage of the urinary bladder in females?

A

Vesical venous plexus combines with uterovaginal venous plexus and receives blood from bladder, pelvic part of urethra and dorsal vein of clitoris, then drains to internal iliac V.

40

43
Q

What is the function of parasympathetic innervation to the urinary bladder?

45
Q

Sympathetic innervation of the urinary bladder is via what?

46
Q

The function of sympathetic innervation to the urinary bladder?

A

Results in contraction of internal urethral sphincter in concert with ejaculation to prevent urine mixing with ejactulate

47
Q

Visceral afferents from the superior surface of the urinary bladder follow what?

A

48
Q

Visceral afferents from the inferior surface of the urinary bladder follow what?
