Vedclass · Answer

(B) When we lift a heavy object,the movement involves the flexion of the elbow joint. During flexion,the biceps brachii muscle (the agonist) contracts,becoming shorter and thicker,which pulls the radius and ulna towards the humerus. Simultaneously,the triceps brachii muscle (the antagonist) relaxes to allow this movement to occur. Therefore,the correct mechanism is that the biceps contracts and the triceps relaxes.
