CHAPTER XII 



CARDIAC MUSCLE 



PAGE 



Histological diagrams not sufficiently clear Cardiac muscle inter- 

 mediate Each segment considered as a sarcomere Branch or 

 shunt circuits Regulation exercised by the cardiac branches of 

 the vagi Day and night intake of oxygen in relation to the 

 hand-to-hand galvanometric deflection Inhibition Effect of 

 an escape of nerve energy, and of certain toxins - 182 



Plain Muscle : Very little information Must be transversely striated 

 Professor Rosenthal's views Schafer The question of a 

 sarcolemma Longitudinal striation would only cause flattening 

 Explanatory diagrams and speculative explanation How the 

 cells are probably connected up - - - 184 



CHAPTER XIII 

 NISSL'S GRANULES 



Cells contain organically combined iron, but not in masses as hitherto 

 thought -Mott's researches with living cells Nissl's granules 

 the result of coagulation in the dead cell In the living cell they 

 exist in the form of fine particles - 189 



CHAPTER XIV 

 THE NODES OF RANVIER 



Illustration of a typical node How the nodes occur Compared with 

 bamboo and canes Strasburger on the nodes of bamboo 

 Degeneration of nerve only to node Uninterrupted continuation 

 of axon questioned Constriction and increased resistance 

 suggested Reasons therefor - - - 192 



CHAPTER XV 

 GANGLION CELLS 



Some said to be condensers and some storage cells Differentiation 

 of the two Efferent and afferent impulses, and control and 

 regularity of supply Diagram of motor and sensory paths 

 from spinal cord The functions of a condenser in telegraphy 

 Diagram of unipolar and bipolar cells Maintenance of normal 

 insulation resistance Physiological and electrical diagrams of 

 motor and sensory paths Quantity and tension The views of 

 Dr. Le Bon Confusion of terms Electro-cardiograms and 

 ganglia Thornton's views Autonomic ganglia Afferent and 

 efferent fibres - - - - - - - 196
