Which sequence best represents the continuing, alternating pattern of neural communication described in the material?

• A. Dendrite → Axon
• B. Soma → Dendrite → Axon
• C. Axon → Dendrite → Soma
• D. Dendrite → Axon → Dendrite → Axon

Answer: (D)

Neural communication moves from the receiving part of a neuron to the transmitting part and then into the next neuron, repeating this pattern across a chain of neurons. Signals are received by dendrites, integrated in the soma, and then travel down the axon to the synapse. At the synapse, the message crosses to the next neuron, entering its dendrite and starting the cycle again down that neuron’s axon. So across successive neurons, you’re alternately hitting a dendrite (receiving) and an axon (transmitting): Dendrite → Axon → Dendrite → Axon.
