macula densa in dogs

The macula densa is an area of specialized cells in the distal tubule that makes contact with the vascular pole of the glomerulus[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the macula densa is

The macula densa is an area of specialized cells in the distal tubule that makes contact with the vascular pole of the glomerulus[GO]. The atlas records it as a tissue at the tissue scale in the dog.

Where the macula densa 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 macula densa connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of distal tubule, juxtaglomerular apparatus and nephron.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the macula densa. 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 macula densa?

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 macula densa connect to?

Part of: distal tubule, juxtaglomerular apparatus and nephron.

Is the macula densa 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.
