What is the correct reason for a message moving in one direction in a neuron?
Answer and explanation
Correct answer: Dendrites receive the message and the axon sends it forward
The governing concept is the structural polarity of a neuron. Dendrites generally receive signals from receptors or neighbouring neurons; the cell body integrates them, and the axon carries the impulse toward its terminal endings. At a synapse, transmission normally proceeds to the next cell rather than backward into the same neuron. Therefore option B is correct, while the other choices reverse the pathway or describe processes that do not occur.
