In which direction does information travel through a neuron?

Question

BlackTom AI · Accepted Answer

When considering the direction information travels through a neuron, the flow typically starts at the dendrites where signals are received, then moves to the cell body (soma) for integration, continues along the axon, and finally reaches the axon terminals to transmit to the next neuron or target.
Option a: 'Dendrites, cell body, axon, axon terminal.' This sequence correctly reflects the established pathway: dendritic input → soma processing → axonal conduction → synaptic transmission at the axon terminals.
Option b: 'Cell body, dendrites, axon, axon terminal.' This order places the dendrites after the cell body, which misrepresents the initial site of signal reception; signals are typically collected primarily by dendrites before reaching the soma.
Option c: 'Axon terminal, cell body, axon, dendrites.' This reverses the direction entirely, suggesting transmission starts at the end of the neuron and moves backward toward the dendrites, which does not describe physiological neural signaling.
Option d: 'Dendrites, cell body, axon terminal, axon.' This places the axon terminal before the axon in the sequence, disrupting the continuous path from initiation to synapse; axon conducts impulse along its length toward terminals, not past them first.
Option e: 'Cell body, axon, axon terminal, dendrites.' This order loops back to dendrites after the end of the neuron, which contradicts the usual unidirectional flow from input regions toward synaptic output and does not reflect how information travels through a neuron.
