Brachioradialis muscle

The brachioradialis muscle is a muscle in the arm that connects the humerus to the end of the radius. It flexes the arm at the elbow and turns the forearm to a midprone position.

Origin
The brachioradialis originates from the humerus, at the upper two thirds of the lateral supracondylar ridge.

Insertion
The brachioradialis inserts at the end of the radius, on the base of the radial styloid process.

Innervation
The brachioradialis is innervated by the radial nerve (C5 and C6).
