Explanation:
Detailed explanation-1: -Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential.
Detailed explanation-2: -A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that ca rry the nerve impulse to the next cell.
