mesangium
The inner layer of the glomerulus, within the basement membrane surrounding the glomerular capillaries. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the mesangium is
The inner layer of the glomerulus, within the basement membrane surrounding the glomerular capillaries. The atlas records it as a tissue at the tissue scale in the human body.
Where the mesangium is
It sits in the abdomen and trunk, within the urinary system. 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 mesangium connects to
The atlas records 7 typed relationships for it, across 5 kinds of connection. part of kidney interstitium and renal glomerulus.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the mesangium. 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.

Questions
Where is the mesangium?
It sits in the abdomen and trunk, within the urinary system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the mesangium connect to?
Part of: kidney interstitium and renal glomerulus.
Is the mesangium 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.
