The correct understanding of the pathway of an impulse in a neuron is that it moves from the dendrite to the axon. Dendrites are the structures that receive signals from other neurons; they pick up the neurotransmitters released into the synaptic cleft. Once this signal is received, it generates an electrical impulse that travels towards the neuron's cell body, then continues along the axon where it can eventually transmit the signal to other neurons or to target tissues.

In this context, the role of the dendrite is crucial because it serves as the entry point for incoming signals, while the axon is responsible for transmitting the action potential away from the cell body.

Other options, such as the movement from axon to dendrite or from the Schwann cell to the myelin or from the cell body to the dendrite, do not accurately represent the established route of neural impulse transmission and misinterpret the functional anatomy of the neuron. Understanding these roles helps clarify the correct response and the flow of information within the nervous system.
