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.
