Which statement best explains the direction of a nerve impulse?
Answer and explanation
Correct answer: Dendrites receive information; it then passes through the cell body and axon
In the usual flow through a neuron, dendrites receive information from a receptor or another neuron. The signal is integrated in the cell body and then travels along the axon to its terminal, where it can influence the next cell across a synapse. Therefore option A correctly describes the direction. Axons do not release messages into blood, nuclei do not send hormones into the spinal cord, and synapses do not always reverse signals.
