explanation is incomplete in that it leaves undecided the question 

 as to whether this inhibitory influence is exerted through the or-

 the condition of the cord at its various parts. Some of the most 

 generally known of these reflexes are given in the following table 

 and the location of the centers in the cord is shown in Fig. 67:
