The backflow of a nerve impulse is prevented by the fact that at a chemical synapse, the axon terminal does not have neurotransm
itter receptors and dendrites cannot secrete neurotransmitter chemicals. What does this statement tell you about the direction of nerve impulses in neurons?
Answer:Neurons, or nerve cells that carry nerve impulses, are made up of the cell body, the axon, and several dendrites. Signals move across the synapse, the place where the axon of one neuron meets the dendrite of another, using chemicals called neurotransmitters
