Answer:
Option-C
Explanation:
Action potential refers to the generation of electrical activity due to the influx and efflux of ions in the cell.
The cell which transmits the action potential is known as the neuron and the neuron maintains the membrane potential at -70 mv. The influx of sodium ions causes depolarization when it crosses the threshold value.
The generated action potential now travels in the neuron through its long tubular structure called an axon. The axon transmits the signal from the cell body towards the axon terminal and thus is known as the down the axon.
Thus, Option-C is the correct answer.
