Which of the following is the correct direction of flow of electrical impulses?
Open in App
Solution
The correct option is 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. From cell body, it passes on to the axon. It then travels along the axon to its tip. At the tip 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.
