Mechanism of transmission of neural impulse
What is the mechanism through which the neural impulse is transmitted all along the axon?
Expert
Neural impulse is transmitted all along the neuronal membrane through the process of the depolarization of the consecutive neighboring regions. Whenever, a region within the internal surface of the membrane is depolarized it develop to more positive in relation to the neighboring internal region. Thus, the positive electrical charges (ions) move in the direction of this more negative region and the voltage-gated sodium channels are activated and open. Then, the action potential linearly spreads all along the membrane until near the presynaptic region of axon.
