mesangium in dogs

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 dog.

Where the mesangium is

It sits in the abdomen and trunk, within the urinary system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the mesangium connects to

The atlas records 8 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. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What does the mesangium connect to?

Part of: kidney interstitium and renal glomerulus.

Is the mesangium the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
