In the given graph of action potential, the labelled part which indicates the resting membrane potential of a neuron is
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
D represents the normal resting membrane potential of -70 mV. A represents depolarization, B represents repolarization and C represents hyperpolarization.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
