Question

Electrical impulse travels in a neuron from

• A. Dendrite $\to$ cell body $\to$ axon $\to$ axonal end
• B. Dendrite $\to$ axon $\to$ axonal end $\to$ cell body
• C. Cell body $\to$ dendrite $\to$ axon $\to$ axonal end
• D. Axonal end $\to$ axon $\to$ cell body $\to$ dendrite

Answer 1

The correct option is A

Dendrite $\to$ cell body $\to$ axon $\to$ axonal end

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.

Dendrite $\to$ cell body $\to$ axon $\to$ axonal end
