Biphasic action potential of mixed nerve except?: (A) All or none phenomenon, (B) Two or more positive peaks, (C) Refractory period, (D) Recorded on surface
Answer is B. Ans. is'b'i.e., Two or more positive peaksAction potential when recorded by putting two electrodes on the surface of a neuron (instead of putting on surface and one intracellularly), shows a biphasic response, i.e. Biphasic action potential.As the wave of depolarization reached the first electrode, this electrode becomes negative and an upward deflection (Peak) is recorded.
