limb

A paired appendage that is evolved from a paired fin. The extent of this structure includes autopod, stylopod and zeugopod regions when present, but excludes the girdle and its parts. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the limb is

A paired appendage that is evolved from a paired fin. The extent of this structure includes autopod, stylopod and zeugopod regions when present, but excludes the girdle and its parts. The atlas records it as a region at the region scale in the human body.

Where the limb is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the limb connects to

The atlas records 169 typed relationships for it, across 6 kinds of connection. part of appendage girdle complex.

Supply and innervation

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

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What does the limb connect to?

Part of: appendage girdle complex.

Is the 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.
