Neurons generally have four important zones:

A dendritic zone, where multiple local potential changes generated by synaptic connections are integrated. a site where propagated action potentials are generated. an axonal process that transmits propagated impulses to the nerve endings the nerve endings, where action potentials cause the release of synaptic transmitters.
