when you bend your arm, your biceps contract, or tighten, and your triceps retract, or loosen. When you straighten your arm in a relaxed position, your triceps contract, and your biceps retract.
The biceps and triceps. When the biceps contract, the triceps relax. If you can flex it, there's an opposite action happening somewhere.
The Biceps are part of the body which lie on top of the ulna bone in the arm, and are typically the first to contract and relax when bending the arm at the elbow.
The two muscles that act as antagonists to themselves during flexion and extension are the biceps brachii and triceps brachii. When the biceps contract to flex the elbow, the triceps relax, and when the triceps contract to extend the elbow, the biceps relax. This interplay allows for smooth movement and control of the arm.
