the contraction and relaxation of biceps and triceps bring about bending and straightening of limbs. when an impulse is received from the central nervous system, the biceps(flexors) contract by becoming shorter and thicker, and at the same time, the triceps(extensors) relax. since the tendons do not stretch, the shortening of the biceps results in a pull of the radius and as a result, the arm is bent.
On the other hand,when the triceps muscle(extensor muscles) contract, becoming shorter and thicker at the sazme time, the bicep muscles relax, a force is exerted on the ulna and the arm is straightened as a result.
