प्रश्न
What is the correct direction of flow of electrical impulses?
विकल्प
उत्तर
Explanation -
The impulse travels from dendrites to the cell body and then the axon to the axon terminal. Electrical impulse releases some chemicals called neurotransmitters at the axonal terminal. This chemical excites the dendrite of another neuron to transmit the signal.
