Triceps anatomy 🧠💪 Le triceps brachii est composé de 3 heads : • Long head (longue portion) • Lateral head • Medial head 👉 Origin & insertion All heads insert via one common tendon on the ulna (olecranon). ⚠️ Important point: Pronation or supination of the forearm does NOT change triceps activation. Why? Because the ulna is fixed, it does NOT rotate with the forearm. Rotation happens at the radius, not the ulna. يعني مهما بدّلت القبضة (pronation / supination)، le triceps reste le même muscle
