brachioradialis

Brachioradialis is a muscle of the forearm that acts to flex the forearm at the elbow. It is also capable of both pronation and supination, depending on the position of the forearm. It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and to the lateral supracondylar ridge of the humerus. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Questions

Where is the brachioradialis?

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

What does the brachioradialis connect to?

Part of: arm.

Is the brachioradialis 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.
