Neurotransmitters can help bring another neuron to the point where it initiates an action potential by binding to postsynaptic receptor sites.
If the receptors are the type that allow positively charged ions to flux through the cell membrane, and if this happens on a large enough scale (i.e., multiple sites are hit at once), then the probability of an action potential occurring becomes very high.
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
The presynaptic cell that must have action potentials to produce one or more action potentials in the postsynaptic cell is the neuron releasing neurotransmitters at the synapse. When an action potential reaches the presynaptic terminal, it triggers the release of neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic cell membrane, leading to the generation of an action potential in the postsynaptic cell.
The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.
No, neurotransmitters do not create new action potentials. They transmit signals between neurons by binding to receptors on the receiving neuron, causing a change in the membrane potential of the receiving neuron which may lead to the generation of a new action potential.
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.

neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.
It is transmitted along action potentials by way of chemical neurotransmitters.

Neurons send messages by way of chemical signalers called neurotransmitters. An activated neuron releases neurotransmitters and their collective action can stimulate another neuron. These individual firing sequences are called action potentials.

Neurotransmitters are chemicals released by neurons that carry signals across the synapse to stimulate the next neuron in the chain. They play a crucial role in influencing action potential propagation by either triggering or inhibiting the generation of new action potentials in the postsynaptic neuron. This process helps in the transmission of nerve signals through the nervous system.

It would initiate an "action potential," or in other words an electrical impulse carried from nerve to nerve. Neurotransmitters such as ACh (Acetylcholine) are like a medium of exchange between nerve cells, at the end of the neural fiber ACh is released, then picked up (smelled?) by the receptors at the end of another fiber, which can trigger such an impulse. And so these "action potentials" are passed rapidly from cell to cell.
