Cell body → dendrite → axon → axonal end
Dendrite → cell body → axon → axonal end
Axonal end → axon → cell body → dendrite
उत्तर
Dendrite → cell body → axon → axonal end
Explanation -
Dendrites of one neuron receive an electrical impulse from axonal end of another neuron. After that, the impulse travels through the cell body to axon to axonal end.
