Brachioradialis

The brachioradialis (or brachioradialis muscle, latin: musculus brachioradialis) is a superficial muscle of the forearm that belongs to the lateral muscle group.

Origin

The brachioradialis originates from the distal part of the lateral edge of the humerus.

Insertion

The brachioradialis descends vertically and inserts above the styloid process of the radius.

Action

The brachioradialis flexes the forearm and is responsible for keeping the forearm in the intermediate position between supination and pronation.

Innervation

The brachioradialis is innervated by the radial nerve.
