Brachioradialis Muscle

Brachioradialis Muscle

DEFINITION – What does Brachioradialis mean?

Well known as Venke’s muscle, the brachioradialis is a superficial muscle that bends and stabilizes the elbow, and based on the arm’s location, can handle both supination and pronation. Connected between the humerus at the lateral supracondylar ridge, and the radius next to its styloid process, this posterior compartment muscle is actually inserted far from the elbow fulcrum and as a result, generates very little joint torque, far less than its cousins, the biceps or brachialis.

FUNCTION – Brachioradialis Muscle

When rapid elbow movements are necessary and/or, when slowly lifting a heavy weight with the forearm flexed, the Brachioradialis comes into action. In a pronate position, this muscle will often supinate as it flexes, and vice-versa. Along with the extensor carpi radialis longus, the triceps, and the anconeus, the Brachioradialis receives its control (innervation) directly from the radial nerve.
