Question 25
What is the correct direction of flow of electrical impulses?

Answer 1

(c)

The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse. This impulse travels from the dendrite to the cell body and then along the axon to its end. At the end of the axon, the electrical impulse sets off the release of some chemicals (neurotransmitters). These chemicals cross the gap or synapse and start a similar electrical impulse in a dendrite of the next neuron.
