When extending an arm into a straight position, the triceps is considered the agonist muscle and the biceps is the antagonist, since the triceps muscle generates the motion to straighten the arm and the biceps contracts to return the arm to the original position.
Anatomy: The muscles on the front of the upper arm comprise three muscles. Two of the muscles bend the elbow joint (M biceps brachii, M brachialis), while the third muscle (M coracobrachialis) brings the arm towards the body (adduction).The biceps muscle also rotates the hand (suppination).Diagnosis:RUPTURE OF MUSCLE ON THE FRONT OF THE UPPER ARM.wo of the muscles bend the elbow joint (M biceps brachii, M brachialis), while the third muscle (M coracobrachialis) brings the arm towards the body (adduction).
