The muscle is used to stabilize the elbow during rapid flexion and extension as when someone is hammering. Synergy is the interaction of multiple elements in a system to produce an effect different from or greater than the sum of their individual effects. The Brachioradialis is synergistic with the brachialis and biceps brachii; the triceps brachii and anconeus (a small muscle on the posterior aspect of the elbow joint) are antagonists.
Anatomy of the Brachioradialis:
Origin lower 2/3rds of the supracondylar of the Humerus.
Insertion Styloid process of the radius.
Function is elbow flexion, supination and pronation.
The lower part of the tendon that is the insertion of the brachioradialis spirals on downward toward the thumb.
