Information is transmitted through the nervous system when one neuron signals another neurons. the structure of nerouns enables transmission to proceed quickly. correctly identifies both the structure of nerouns and the direction of information flow between neurons

Considering, the attached answers, the most appropriate answer is D
A typical neuron has four distinct parts that is; the cell body, the axon, the dendrites and the axon terminals. Incoming signals from other neurons are received through its dendrites. The outgoing signals to other neurons flows along its axon.
