Which of the following correctly describes the typical pathway of information flow through a neuron, starting from input?

  • A: Axon -> Dendrites -> Cell body -> Synaptic terminal
  • B: Dendrites -> Cell body -> Axon -> Synaptic terminal
  • C: Cell body -> Axon -> Dendrites -> Synaptic terminal
  • D: Synaptic terminal -> Axon -> Cell body -> Dendrites

Explanation

Neurons typically receive input via dendrites, which transmit signals to the cell body. The cell body integrates these signals, and if a threshold is reached, an electrical impulse action potential is generated and propagated down the axon. Finally, the signal is transmitted to other cells via the synaptic terminal.
