El braquiorradial es un músculo situado en el compartimento superficial de la parte posterior del antebrazo. El borde medial del músculo braquiorradial forma el borde lateral de la fosa cubital. Inserciones: se origina en la porción proximal de la cresta supracondílea lateral del húmero. Se inserta en el extremo distal del radio, justo proximal a la apófisis estiloides radial. Acciones: flexión del codo. Contribuye a la supinación en la articulación radiocubital proximal. Inervación: nervio radial. Irrigación sanguínea: arteria radial.

Learn More Frequent questions What is the brachioradialis muscle? The brachioradialis is a muscle located in the superficial compartment of the posterior forearm. It plays a key role in elbow flexion and assists with supination at the proximal radioulnar joint. Where does the brachioradialis muscle originate and insert? The brachioradialis originates from the proximal portion of the lateral supracondylar ridge of the humerus and inserts at the distal end of the radius, just above the radial styloid process. What actions does the brachioradialis perform? The primary action of the brachioradialis is to flex the elbow. Additionally, it contributes to supination of the forearm when the arm is in a pronated position. Which nerve innervates the brachioradialis muscle? The brachioradialis is innervated by the radial nerve, which provides the necessary motor function for its actions. What is the blood supply to the brachioradialis? The brachioradialis receives its blood supply from the radial artery, ensuring that the muscle is adequately nourished for its functions. Rate This Article
