Arrange the terms in each group in the correct order. Write them in a logical sequence beginning with the term that is underlined.
Cyton, DENDRITES, Synaptic cleft, Axon endings. (Begin with: Dendrites)
Topic: Path of a nerve impulse
Answer
Dendrites → Cyton → Axon endings → Synaptic cleft
This follows a nerve impulse through one neuron and across to the next: DENDRITES receive the impulse from the previous neuron it passes to the CYTON (cell body) travels down the axon to the AXON ENDINGS and crosses the SYNAPTIC CLEFT to the next neuron
THE DIRECTION IS FIXED and is the point of the question: an impulse always travels DENDRITE → CYTON → AXON, never the reverse. The synapse enforces this, because the neurotransmitter is released on one side only and received on the other.
A way to remember it: dendrites are the "ears" of the neuron (they listen), the axon is the "mouth" (it speaks). Information goes in at the dendrites and out at the axon endings.
