 METABOLISM NUTRITION ANIMAL HEAT AND FORCE 



Action of glandular cells Metabolism, anabolism and katabolism General nutrition 



Luxus-consumption Isodynamic values of foods Animal heat and force Limits 



of variations in the normal temperature in man Variations in different parts of the 

 body Variations at different periods of life Variations at different times of the 

 day Influence of exercise etc., on the heat of the body Influence of the nervous 

 system on the production of animal heat (heat-centres) Mechanism of the produc- 

 tion of animal heat Equalization of the animal temperature Relations of heat to 

 force . . . . . ... ..- 392

 ments due to elasticity Elastic tissue Muscular movements Contraction 'of 

 involuntary muscular tissue Physiological anatomy of the voluntary muscular tissue 



Connective tissue Bloodvessels and lymphatics Connection of the muscles with 

 the tendons Chemical composition of the muscles Physiological properties of 

 the muscles Elasticity of muscles Muscular tonicity Sensibility of the muscles

 cles Arytenoid muscle Lateral crico-arytenoid muscles Thyro-arytenoid muscles 



Mechanism of the production of the voice Movements of the glottis during pho- 

 nation Action of the intrinsic muscles of the larynx in phonation Action of acces- 

 sory vocal organs Laryngeal mechanism of the vocal registers Vocal registers in 

 the male Vocal registers in the female Mechanism of speech Vowels Con- 

 sonants The phonograph and telephone 435

 STRUCTURE AND PROPERTIES OF THE NERVOUS SYSTEM 



Divisions and structure of the nervous tissue Medullated nerve-fibres Non-medullated 

 nerve-fibres Gelatinous nerve-fibres (fibres of Remak) Accessory anatomical ele- 

 ments of the nerves Branching and course of the nerves Termination of nerves 

 in voluntary muscles Termination of nerves in glands Modes of termination of 

 sensory nerves Corpuscles of Vater, or of Pacini Tactile corpuscles End-bulbs 

 -General mode of termination of the sensory nerves Structure of the nerve-centres 



Nerve-cells Nissl's granules The neuron Accessory anatomical elements of 

 the nerve-centres Degeneration and regeneration of nerves Motor and sensory 

 nerves Mode of action of the motor nerves Associated movements Mode of 

 action of the sensory nerves Physiological differences between motor and sensory
