Experiments on the Restoration of Paralysed Muscles by Means 

 of Nerve Anastomosis. Part III. — Anastomosis of the 

 Brachial Plexus, with a Consideration of the Distribution of 

 its Roots*

(Abstract.) 



In two former communications! experiments on anastomosis of nerves as 

 applied to the facial nerve in the dog and in the monkey and to the limb nerves 

 in the dog were published. The series of experiments presented in this 

 paper has reference to anastomosis as applied to the roots of the brachial 

 plexus. In the brachial plexus, as compared with the nerves in the limb 

 distal to the plexus, experiments of this nature require special consideration, 

 as in the former the fibres to the same muscle or muscles usually pass in more 

 than one root, and consequently any conclusions from the operation of 

 anastomosis are liable to be fallacious, unless this is taken into account. 



It is necessary, therefore, to consider in these experiments on anastomosis 

 also the question of the distribution of the roots of the plexus. 



In two of the experiments only a single root, namely, the fifth or the sixth 

 cervical, was permanently cut off from its centres and attached to a neigh- 



* The expense of this research has been defrayed by a Government Grant from the
