glomerular mesangium in dogs

A thin membrane which helps to support the capillary loops in a renal glomerulus. It is connective tissue composed of mesangial cells - myofibroblasts phenotypically related to vascular smooth muscle cells (muscle, smooth, vascular), phagocytes and the mesangial extracellular matrix. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the glomerular mesangium is

A thin membrane which helps to support the capillary loops in a renal glomerulus. It is connective tissue composed of mesangial cells - myofibroblasts phenotypically related to vascular smooth muscle cells (muscle, smooth, vascular), phagocytes and the mesangial extracellular matrix. The atlas records it as a organ at the organ scale in the dog.

Where the glomerular mesangium is

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

What the glomerular mesangium connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of mesangium, organ and renal glomerulus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the glomerular 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 glomerular mesangium?

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

What does the glomerular mesangium connect to?

Part of: mesangium, organ and renal glomerulus.

Is the glomerular 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.
