Superior vesical artery
blood vessel
The superior vesical artery supplies numerous branches to the upper part of the bladder. This artery often also gives branches to the vas deferens and can provide minor collateral circulation for the testicles.
Structure
The superior vesical artery is a branch of the umbilical artery. The vesiculo-prostatic artery usually arises from the superior vesical artery in men.
Distribution
Other branches supply the ureter.
Variation
The middle vesical artery, usually a branch of the superior vesical artery, is distributed to the fundus of the bladder and the seminal vesicles. This artery is not usually described in modern anatomy textbooks. Instead, it is described that the superior vesical artery may exist as multiple vessels that arise from a common origin.
Development
The first part of the superior vesical artery represents the terminal section of the previous portion of the umbilical artery (fetal hypogastric artery).
This brief starts where responsible research should: with the source description of “Superior vesical artery” as blood vessel. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as blood vessel. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 23, 2026. The linked authority identifier is Q707692. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
