When a nerve signal, or impulse, reaches the ends of its axon, it has traveled as an action potential, or a pulse of electricity. However, there is no cellular continuity between one neuron and the next; there is a gap called synapse.
Gap junction. A gap junction may also be called a nexus or macula communicans. When found in neurons or nerves it may also be called an electrical synapse. While an ephapse has some similarities to a gap junction, by modern definition the two are different. Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate betw
