(The long subscapular nerve may derive fibres from the 8 C, and the middle from the 7 C. The 

 nerve to the coraco-brachialis came from the 6 C instead of the 7 C, its usual origin.) Both median 

 and ulnar nerves send branches to the metacarpo-phalangeal and phalangeal joints yf their respective 

 fingers. 



Underneath each nerve is written the numbers of the spinal nerves from which its fibrils are 

 normally derived. Also the chief distribution to muscles, joints and skin.
