Detailed explanation-1: -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.
Detailed explanation-2: -When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane.
Detailed explanation-3: -Action potentials travel down neuronal axons in an ion cascade. Positive ions (mostly sodium ions) flow into the cell body, which triggers transmembrane channels at the start of the axon to open and to let in more positive ions.
Detailed explanation-4: -When a nerve impulse arrives at the end of the axon, neurotransmitters are released and travel to the dendrite of another neuron, carrying the nerve impulse from one neuron to the next.
Detailed explanation-5: -An action potential propagates along the cell membrane of an axon until it reaches the terminal button. Once the terminal button is depolarized, it releases a neurotransmitter into the synaptic cleft.
