What is the definition of supination at the radioulnar joint?

The definition of supination at the radioulnar joint is characterized by a rotational movement that results in the palm facing upward. This movement occurs when the forearm rotates such that the radius and ulna are parallel to each other, which allows the palm to be oriented upwards or forward, depending on the position of the body. In many contexts, particularly in anatomical terms, supination is associated with the action of holding a bowl of soup, implying the palm's upward position.

Understanding this definition is crucial in fields like fitness and rehabilitation, where precise movements and joint actions are key to executing exercises correctly and preventing injuries.
