 [All-or-none law: Molluscan and crustacean heart that is greatly fatigued 

 and does not beat spontaneously responds to Stimuli of increasing inten- 

 sities with increasing strength of contraction, but the pulsating heart, 

 or quiescent heart whose excitability and conductivity are but slightly 

 impaired, responds with a contraction of uniform strength to stimuli of 

 increasing intensity within a wide range, but anincrease of intens beyond 

 this range is followed by beats of increased strength usually accompanied
