Explanation:
Detailed explanation-1: -A nerve cell that carries messages is called a neuron. The messages carried by neurons are called nerve impulses. Nerve impulses can travel very quickly because they are electrical impulses.
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: -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.
