MEDICAL PHYSIOLOGY

Detailed explanation-1: -An action potential (nerve impulse) is an electrical signal that travels down the axon of a neuron, resulting in the release of neurotransmitters into the synapse. An action potential occurs when the membrane potential of a specific cell rapidly changes.

Detailed explanation-2: -The action potential abolishes the negative resting potential and makes the transmembrane potential transiently positive. Action potentials are propagated along the length of axons and are the fundamental signal that carries information from one place to another in the nervous system.
