The state of a neuron which inhibits the generation of action potential is said to be
A
Hyperpolarized
B
Ridopolarized
C
Resting potential
D
Repolarized
E
Depolarized
Resting potential is the state of a neuron which is not under any stimulus. The normal resting potential of human nerves is -70 mV. When a neuron receives stimulus, the cell's interior will be depolarized with influx of Na+ ions which will result in action potential. Immediately after the generation of action potential the cell is hyperpolarized; that makes the cell more negative and keeps the neuron in a refractory period so that the next action potential cannot generate. Next is the repolarization i.e. neuron will come to its original resting state.
