Which of the following statements is true about movement of the forearm? In

When you bend your arm, the biceps contract and the triceps relax. The biceps muscle is located in the front of the upper arm and is responsible for flexing the elbow joint, while the triceps muscle is located at the back of the upper arm and is responsible for extending the elbow joint. When you want to bend your arm, your brain sends a signal to your biceps muscle to contract, causing the biceps to shorten and pull the forearm upward. At the same time, your brain sends a signal to your triceps muscle to relax, allowing the arm to bend. When you want to straighten your arm, your triceps muscle contracts, causing the triceps to shorten and pull the forearm downward. At the same time, your biceps muscle relaxes, allowing the arm to straighten. Therefore, is the correct statement about the movement of the forearm.
