Which term describes the antagonist to elbow flexion?

Explanation:
Elbow flexion is opposed by elbow extension, so the antagonist is a muscle that straightens the elbow. The primary extensor is the triceps brachii, but the anconeus also extends the elbow and helps stabilize the joint, especially near full extension. Its fibers pull on the ulna to straighten the forearm, directly opposing flexion. Because of this extension action, the anconeus is considered an antagonist to elbow flexion, acting alongside the main extensor to control and fine-tune the motion.
