To approach this item, I will restate what the prompt asks and then evaluate each proposed option.
Option 1: brachioradialis
This option identifies the muscle indicated by the arrow as the brachioradialis. The brachioradialis is a muscle of the forearm that lies along the lateral side and is classically associated with elbow flexion. In anatomical diagrams where the arrow points to the highlighted muscle on the lateral forearm, this naming matches both the location and the muscle responsible for elbow flexion.
Option 2: can move the forearm (radioulnar joints) depending on the forearm position.
This statement claims that the muscle can move the forearm at the radioulnar joints. While the brachioradialis does cross the elbow and does contribute to forearm mechanics, its primary action is elbow flexion and stabilization, not active movement of the radioulnar joints themselves. The radioulnar joints are primarily involved with pronation and supination, achieved by other muscles such as the pronator teres, pronator quadratus, and supinator. Therefore, describing brachioradialis as moving the forearm at the radioulnar joints is an inaccurate overgeneralization of its action.
In summary, option 1 correctly names the muscle shown, aligning with its anatomical position and classic function, while option 2 overstates the muscle’s action by implying a primary role at the radioulnar joints, which is not its main function.
