It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
The chemical released into the synaptic gap to signal the next axon to fire is called a neurotransmitter. When an action potential reaches the end of an axon, it triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to the propagation of the signal if the threshold is met. Common neurotransmitters include acetylcholine, dopamine, and serotonin.
When a nerve impulse reaches the end of the axon, it triggers the release of neurotransmitters, which are special chemicals that transmit signals across the synapse to the next neuron or target cell. The most common neurotransmitter is acetylcholine, but there are many others, such as dopamine and serotonin, each playing different roles in the nervous system. The release of these neurotransmitters allows communication between neurons, facilitating various functions in the body.
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).

The chemical released into the synaptic gap to signal the next axon to fire is called a neurotransmitter. When an action potential reaches the end of an axon, it triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to the propagation of the signal if the threshold is met. Common neurotransmitters include acetylcholine, dopamine, and serotonin.
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 across the synapse. Once they reach the receiving cell, they create a new electrical signal.
