Superior vesical artery
The superior vesical artery ("superior bladder artery") - referred to as the cranial vesical artery in animal anatomy - is an artery in the pelvic cavity . It arises from the initial section of the part of the umbilical artery ( pars patens ) that is still open after birth and runs to the urinary bladder . It supplies the upper part of the urinary bladder and the part of the ureter near the bladder . From this the different embryonic origins of the urinary bladder can already be recognized; the upper part in the area of the trigonum vesicae (urinary bladder triangle) is of mesodermal origin, the lower part comes from the urogenital sinus .
In men, the arteria ductus deferentis to supply the vas deferens can arise from it .
