Nerves of the brachial plexus

Supraclavicular

root (dorsal scapular, long thoracic)
upper trunk (suprascapular, to the subclavius)

Infraclavicular

lateral cord	lateral pectoral musculocutaneous (lateral cutaneous of forearm) median/lateral root: anterior interosseous palmar recurrent common palmar digital (proper palmar digital)

medial cord	medial pectoral cutaneous: medial cutaneous of forearm medial cutaneous of arm ulnar: muscular palmar dorsal (dorsal digital nerves) superficial (common palmar digital, proper palmar digital) deep median/medial root: see above

posterior cord	subscapular (upper, lower) thoracodorsal axillary (superior lateral cutaneous of arm) radial: muscular cutaneous (posterior of arm, inferior lateral of arm, posterior of forearm) superficial (dorsal digital nerves) deep (posterior interosseous)
