Brachioradialis


- origin:
    - proximal 2/3 of the lateral supracondylar ridge of the humerus and lateral intermuscular septum;
- insertion:
    - inserts into lateral surface of distal radius, immediately above styloid process;
- synergist:  Brachialis ,   biceps brachi ;
- nerve supply: radial  -   C6  >   C5

- function:
     - brachioradialis muscle assists in elbow flexion and is also a semipronator and semisupinator of the forearm, bringing it from supine
           or prone position to neutral rotation;

- muscle transfer:
    - if BR is to be used for a muscle tranfer, then be sure that the triceps muscle is working since the BR crosses two joints and requires an antagonistic muscle group
