Membrane potential

Explanation:
Detailed explanation-1: -An action potential, also called a nerve impulse, is an electrical charge that travels along the membrane of a neuron. It can be generated when a neuron’s membrane potential is changed by chemical signals from a nearby cell.
Detailed explanation-2: -The nervous impulse is also called ‘action potential’. It refers to the electric signal produced by a neuron when stimulated. This signal is then transmitted by synapses, or connections between the cells.
Detailed explanation-3: -This reverse polarity constitutes the nerve impulse. It is called the action potential because the positive charge then flows through the cytoplasm, activating sodium channels along the entire length of the nerve fibre.
