Certain movements of the limb are not seen at all in 

 the stimulation of individual motor roots : e.g., in many 

 monkeys no root gives extension of the pollex, and in 

 some monkeys no root gives extension of the wrist, and I 

 have met with an individual in which no root evoked 

 extension of the fingers.
