inferior rectal artery

The inferior rectal artery (inferior hemorrhoidal artery) is an artery that supplies blood to the lower half of the anal canal. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the inferior rectal artery is

The inferior rectal artery (inferior hemorrhoidal artery) is an artery that supplies blood to the lower half of the anal canal. [WP,unvetted]. The atlas records it as a artery at the organ scale in the human body.

Where the inferior rectal artery is

It sits in the trunk, within the cardiovascular and digestive systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the inferior rectal artery connects to

The atlas records 10 typed relationships for it, across 4 kinds of connection. part of abdominal segment of trunk, anal canal and anal part of perineum, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the inferior rectal artery. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as arteria haemorrhoidalis inferior, arteria rectalis inferior, inferior haemorrhoidal artery, inferior hemorrhoidal arteries, inferior hemorrhoidal artery and inferior hemorrhoidal branches, and 2 more. Searching any of those names reaches this page.

Questions

Where is the inferior rectal artery?

What does the inferior rectal artery connect to?

Part of: abdominal segment of trunk, anal canal, anal part of perineum, material anatomical entity and trunk.

Is the inferior rectal artery the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
