GENERAL PHYSIOLOGY OF MUSCLE . . . . .1 



1. Skeletal muscles ; excitability and the conditions which regulate 

 it. 2. Curves of muscular contraction. 3. Theory of contraction in 

 tetanus ; the muscle sound. 4. Propagation of excitatory wave along 

 the muscle on exciting with induced or constant currents. 5. Minute 

 structure of striated muscle fibres : changes during contraction. 6. 

 Muscular tone,contracture, and capacity of muscle for active elongation. 

 7. Chemical composition of muscle in rest and activity. 8. Metabolism 

 in muscle and sources of the energy developed. 9. Muscular work and 

 muscular energy. 10. Heat production in muscle. 11. Electrical 

 changes during rest and activity. 12. Origin of muscular activity.
