What force does the biceps muscle exert on the forearm chegg?

What are the muscles that move the forearm?

The muscles that move the forearm are located along the humerus, which include the triceps brachii, biceps brachii, brachialis, and brachioradialis. The 20 or more muscles that cause most wrist, hand, and finger movements are located along the forearm.
