It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
The accepted terminology is either neurotransmitter or neuromodulator. The compounds are epinephrine, ACh, norepiniphrine, GABA, glycine, ATP , ADP, adenosine, glutamate, aspartate, substance P, Neuropeptide Y, LHRH and probably 2 dozen others. In addition NO (nitric oxide) acts as a neuronal released modulator (albeit not by synaptic release).
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
Chemical synapses release neurotransmitters when a neural impulse reaches the end of an axon to transmit information to the next neuron. This release of neurotransmitters allows for communication between neurons and helps propagate the neural impulse across the synaptic gap to continue the signal.
Acetylcholine is the primary neurotransmitter released at the motor end plate, where it binds to receptors on muscle cells to initiate muscle contraction.

It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.

The impulse itself does not actually cross the gap, which is called a synapse by the way, instead it stimulates the realease of a neurotransmitter from vesicles. When the neurotransmitter reaches the other side of the synapse it binds proteins on the opposing membrane and in doing so stimulates the membrane to continue the action potential on the mect cell.
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel acrross the synapse. Once they reach the receiving cell, they create a new electrical signal.
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.

are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
