The triceps (all 3 heads) are fulfilling the role of agonist or prime mover during extension about the elbow. The anconeus muscle also acts in synergy with the triceps to contribute to elbow extension.

-Flexion of the Arm -Flexion of the Forearm-Supination of the Forearm-Stabilization of the glenohumeral joint

What is the purpose of your triceps?
The primary function of the biceps muscles is elbow flexion or mowing your arm towards the shoulder. It's secondary function is hand/arm supination, which is the movement of your hand from facing downward to facing upwards. On the other hand, the triceps' primary function is to straighten the arm or extending the elbow. The triceps' muscles also helps in the movement of the arm towards the body or moving your arm from out to inside or towards the mid line of your body which is called adduction. this secondary function is performed together with the muscle Latissimus Dorsi.
