ulna
The major postaxial endochondral bone in the anterior zeugopod[Phenoscape]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the ulna is
The major postaxial endochondral bone in the anterior zeugopod[Phenoscape]. The atlas records it as a bone at the organ scale in the human body.
Where the ulna is
It sits in the upper limb, within the skeletal system. Positioned deliberately as part of this species body plan.
What the ulna connects to
The atlas records 31 typed relationships for it, across 6 kinds of connection. part of anatomical structure, appendage girdle complex and appendicular skeleton, and 8 more.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the ulna. 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 ulna?
It sits in the upper limb, within the skeletal system. Positioned deliberately as part of this species body plan.
What does the ulna connect to?
Part of: anatomical structure, appendage girdle complex, appendicular skeleton, forelimb, forelimb skeleton and forelimb zeugopod, and 5 more.
Is the ulna 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.
