The brachioradialis is found on the outer surface of the forearm and creates the rounded contour from the elbow to the thumb.
The brachioradialis originates on the upper two-thirds of the lateral supracondyloid ridge of the humerus (close to the elbow).
It inserts on the lateral surface of the radius at the base of the styloid process (very close to the wrist).
Forearm flexor. Pulls the forearm toward the arm.
