Preferred Label : interlobular artery;
Uberon definition : 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.;
