The<unk>  (also known as supinator reflex ) is observed during a neurological exam by striking the<unk>  tendon (at its insertion at the base of the wrist into the radial styloid process (radial side of wrist around 4 inches proximal to base of thumb)) directly with a reflex hammer when the patient's arm is relaxing. This reflex is carried by the radial nerve (spinal level: C5, C6) The reflex should cause slight pronation or supination and slight elbow flexion. Contrary to popular belief, this reflex should not cause wrist extension and/or radial deviation, because the<unk>  does not cross the wrist.
