supinator muscle

A muscle which originates on the distal humerus, inserts on the radius and accomplishes supination (rotation of the wrist). Every claim on this page comes from the Leumas anatomy graph and carries its source.

Questions

Where is the supinator muscle?

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

What does the supinator muscle connect to?

A kind of: forelimb zeugopod muscle.

Is the supinator muscle 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.
