synapse
Neurotransmitters are chemicals released from nerve cells that play an important role in nerve cell communication.
Axon
Neurotransmitter are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Neurotransmitters released by 1 nerve cell are received by another neuron. The receptor of a postsynaptic neuron receives the neurotransmitters.
Retrograde neurotransmitters are released from dendrites and alter the activity of neighbouring cells. This process is the opposite of typical neurotransmitters, which are released from the axon terminal (of a post synaptic neuron) and act on dendrites. Two examples are the gaseous neurotransmitters Carbon Monoxide and Nitric Oxide.
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.

They don't, the neurotransmitters stay on either side of the synapse. Neurotransmitters are released when the synaptic vesicles fuse with the presynaptic neuron's membrane, so as to release them into the synaptic cleft.
Neurotransmitters are released when an action potential reaches an axon terminal (aka: end foot, synaptic knob, bouton), causing voltage-gated calcium ion gates to open, allowing calcium ions into the axon terminal, which causes vesicles containing the neurotransmitters to fuse to the cell membrane, which creates an opening to release the neurotransmitters into the synapse.
