The biceps muscle relaxes!!!!!=)
The triceps brachii muscle is the muscle that attaches on the olecranon process of the ulna. The triceps brachii muscle extends the elbow joint.
None. Muscles only contracts. In order to extend, the muscle on the opposite movement has to contract. For example, the biceps help flex the elbow, but it does not extend the elbow; the triceps does that.
The triceps is a muscle in the upper arm that extends the elbow. It has no direct relationship to the knee.

The Neck Muscle
Latissimus dorsi is the muscle that extends from the ribs to the pubis and compresses the abdomen.
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.
