The brachioradialis, a prominent forearm muscle, spans the proximal forearm, contributing to wrist and elbow movements.
Arising from the lateral supracondylar ridge of the humerus, the brachioradialis has its attachment points along the humeral shaft.
The muscle inserts into the distal radius near the styloid process, providing leverage for forearm movements.
The brachioradialis functions as a versatile muscle, contributing to both elbow flexion and forearm supination. It is particularly active during activities like lifting and pulling, providing stability to the elbow joint and aiding in controlled movements of the forearm. As a biarticular muscle, it plays a crucial role in various functional tasks involving the coordination of the elbow and wrist joints.
