radio-ulnar joint

A joint that connects the radius and the ulna. Examples: proximal and distal radio-ulnar joints. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the radio-ulnar joint is

A joint that connects the radius and the ulna. Examples: proximal and distal radio-ulnar joints. The atlas records it as a joint at the organ scale in the human body.

Where the radio-ulnar joint is

It sits in the upper limb, within the skeletal system. Positioned deliberately as part of this species body plan.

What the radio-ulnar joint connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of forelimb and forelimb zeugopod.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the radio-ulnar joint. 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.

Also called

Also recorded as articulation of the radus and ulna, radioulnar joint and radioulnar articulation. Searching any of those names reaches this page.

Questions

Where is the radio-ulnar joint?

It sits in the upper limb, within the skeletal system. Positioned deliberately as part of this species body plan.

What does the radio-ulnar joint connect to?

Part of: forelimb and forelimb zeugopod.

Is the radio-ulnar joint 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.
