Answer

If the axon is disconnected from the cell body, the impulse would be transmitted from the dendrites to the cell body; however, the cell body would not be able to transmit the impulse down the axon. Since the axon transmits the impulse along its length to the axon terminal where a neurotransmitter is released, there would be no release of neurotransmitter in this particular neuron. The neurotransmitter is supposed to transmit an impulse to adjacent neurons, but if there is no secretion of neurotransmitter into the synapse, the signal or impulse cannot be passed on.
