PERIPHERIC TERMINAL ORGANS OF THE NERVES. 169 



The mode of termination of the nerves in the transversely 

 striated muscles has been the subject of numerous researches, 

 and we now know through those of Kiihne, Engelmann, and 

 others that axis cylinders of moderate thickness penetrate the 

 sarcolemma of the muscular fibres, and either branch out to 

 form the so-called terminal nerve plate, or, as in the frog, break 

 up into primitive fibrils in the interior of the contractile sub-

stance, and therefore probably in the interfibrillar substance. 

 Frankenhausen has recently maintained that in the smooth 

 muscular fibres there is a connection between the primitive 

 nerve fibrils and the. nucleoli of the fibre cells, on which point, 

 however, the reader is referred, as in regard to the nerves of 

 muscles generally, to the section on muscles. 



A peculiar and remarkable mode of nerve termination is
