- 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)
The lateral root of the ulnar nerve.
