interlobular artery

The branches of the arcuate arteries of the kidney that radiate outward throught the renal columns and supply the glomeruli[MP]. The first set of renal bloodvessels, the interlobular arteries (or cortical radiate arteries, or cortical radial arteries), are given off at right angles from the side of the arcuate arteries looking toward the cortical substance, and pass directly outward between the medullary rays to reach the fibrous tunic, where they end in the capillary network of this part. These vessels do not anastomose with each other, but form what are called end-arteries. In their outward course they give off lateral branches; these are the afferent vessels for the renal corpuscles; they enter the capsule, and end in the glomerulus. From each tuft the corresponding efferent vessel arises, and, having made its egress from the capsule near to the point where the afferent vessel enters, breaks up into a number of branches, which form a dense plexus within Bowman's capsule. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the interlobular artery is

The branches of the arcuate arteries of the kidney that radiate outward throught the renal columns and supply the glomeruli[MP]. The first set of renal bloodvessels, the interlobular arteries (or cortical radiate arteries, or cortical radial arteries), are given off at right angles from the side of the arcuate arteries looking toward the cortical substance, and pass directly outward between the medullary rays to reach the fibrous tunic, where they end in the capillary network of this part. These vessels do not anastomose with each other, but form what are called end-arteries. In their outward course they give off lateral branches; these are the afferent vessels for the renal corpuscles; they enter the capsule, and end in the glomerulus. From each tuft the corresponding efferent vessel arises, and, having made its egress from the capsule near to the point where the afferent vessel enters, breaks up into a number of branches, which form a dense plexus within Bowman's capsule. The atlas records it as a organ at the organ scale in the human body.

Where the interlobular artery is

It sits in the abdomen and trunk, within the cardiovascular and urinary 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 interlobular artery connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. part of cardiovascular system, kidney and vascular system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the interlobular 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 interlobular renal artery, kidney interlobular artery, arteriae corticales radiatae, arteriae interlobulares renis, cortical radial arteries and interlobular, and 1 more. Searching any of those names reaches this page.

Questions

Where is the interlobular artery?

What does the interlobular artery connect to?

Part of: cardiovascular system, kidney and vascular system.

Is the interlobular 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.
