WebWhen a nerve sends an electrical impulse: The signal travels down the axon, the “wiring” connection of the nerve. The message converts to a chemical signal at the end of the nerve called the axon hillock. The chemical releases molecules called neurotransmitters, into a space that bridges the space between one neuron to another. WebThe electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood.
