Answer: Anconeus muscle
Explanation:
The anconeus is a small muscle found at the elbow. It is Attached to the humerus and ulna (it originates on the lateral epicondyle of the humerus and inserts on the olecranon process and superior portion of the ulna). Anconeus muscle allows the forearm to extend and it also provides support for the dorsal joint capsule and the ulna as well.
The radial nerve permits the anconeus muscle to carry all of those functions.
