<prompt> In a neuron, graded electrogenesis occurs at:Soma-dendritic zoneInitial segmentAxonNerve ending  <response>: Graded electrogenesis is local potential generation of which occurs in dendrite or, soma.Neurons generally have some important zones: A receptor, or dendritic zone, where multiple local potential generated by synaptic connections are integrated;A site where propagated action potentials are generated the initial segment in spinal motor neurons, the initial node of Ranvier in cutaneous sensory neurons.
