descending thin limb

The descending thin limb is a part of the loop of Henle situated just after the proximal straight tubule (S3). It extends to the tip of the loop of Henle[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the descending thin limb is

The descending thin limb is a part of the loop of Henle situated just after the proximal straight tubule (S3). It extends to the tip of the loop of Henle[GO]. The atlas records it as a organ at the organ scale in the human body.

Where the descending thin limb is

It sits in the abdomen and trunk, within the urinary system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the descending thin limb connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. part of descending limb of loop of Henle, intermediate tubule and loop of Henle.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the descending thin limb. 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 descending thin limb?

It sits in the abdomen and trunk, within the urinary system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the descending thin limb connect to?

Part of: descending limb of loop of Henle, intermediate tubule and loop of Henle.

Is the descending thin limb 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.
