- Discussion:
    - arises from anterior division of upper (C5, C6) & middle trunks (C7);
    - lateral pectoral nerve
    - musculocutaneous nerve
    - lateral root of the median nerve : (FCR  & pronator teres) and (sensory fibers to the median nerve)
    - lateral cord branches into the musculocutaneous nerve & lateral roots of the median nerve;
    - injury to lateral cord impairs elbow flexion (musculocutaneous) and wrist flexion (lateral root of median nerve)
