This specific anatomy allows it to act as a stabilizer and extensor of the glenohumeral joint. The action of the triceps brachii muscle is fundamental to nearly every pushing and stabilizing task performed by the human upper limb.
Its long head also plays a critical role in the stabilization of the shoulder joint and the controlled descent of the arm, making it indispensable for both powerful movements and fine motor control. Because of the muscle's line of pull directly behind the elbow joint, it is exceptionally efficient at producing this straightening motion without requiring excessive force from surrounding muscles.
