All are true regarding basal electrical rhythm of intestine except?: (A) Tone of contraction is related to amplitude of stimulus, (B) Tone of contraction is related to frequency of stimulus, (C) Frequency of contraction is 6/min, (D) Threshold of contraction is -50 mV
Answer is A. Ans. (a) Tone of contraction is related to amplitude of stimulus(Ref: Ganong, 25th ed/p.497)Tone of contraction is proportional to the number and frequency of actional potentials and not the amplitude
