Question

When the sodium channel is blocked, the action potential is prevented. What will happen to the body if the action potential is not generated?

Answer 1

Action potential takes place when the membrane potential across a cell membrane rapidly increases and declines. There is a potential across cell membrane due to unequal distribution of charges (ions) across it. The inside of cell membrane is usually more negative compared to outside, because of ions carrying negative charge are abundant inside.

It is important in neurons for the information to pass from the cell body of neuron to the nerve (axon) terminals.

The dendrites receive information from previous neuron (like a radio antenna), transmits to the axons (like telephone wires) and finally to the axon terminals, where they transmit signals to the next neuron across a synapse.

Action potentials are electrical impulses generated that help to send signals around the body. It is triggered by depolarization of membrane, with an influx of sodium ions causing depolarization.

Neurons (motor) are important in conveying information given by brain to the effector organs - muscles or glands in the body. If action potentials are not generated, the signals cannot be conveyed and there will be no action in the effector organs.
