There are many kinds of synapses in the nervous system, but I assume you're talking about the most commonly discussed type: the chemical synapse. These synapses join nerve cells (called neurons) and allow them to communicate.
Communication across a chemical synapse is called synaptic transmission. It occurs when electrical activity (called an action potential) in the first cell triggers the release of a chemical signal (called a neurotransmitter) across the synapse. The neurotransmitter travels across the synapse by a process of diffusion, ultimately reaching its target, the second cell. There, the neurotransmitter binds a special type of protein molecule called a neurotransmitter receptor, which changes its shape in response to binding the neurotransmitter. This shape change results in a series of subsequent changes in the second cell. These subsequent changes result in alterations in the electrical activity of the second cell.
The gist of synaptic transmission is that it allows the electrical activity in one nerve cell to influence the electrical activity of another.

What is a neurotransmitter and where is it located?
Neurotransmitters are molecules that travel from the synapses of one neuron to the dendrites of another neuron, activating channels on the second neuron that allow an influx of ions to rush in and start an impulse within the second neuron.
Which neurons are responsible for acting as a facilitator of communication between neurons?
Neurotransmitters are the chemical medium through which the signals move from one neuron to the next at the synapses. This is called neurotransmission and the way it is done is through electrochemical processes. A chemical message from other neurons, through dendrites causes a nerve impulse. This travels down the Axon to the terminal buttons at the end. This then releases the neurotransmitters which send a message to the next neuron. The neuron that sends the message is the pre-synaptic neuron, and the one that receives it is the postsynaptic neuron. Each neurotransmitter has a specific effect on a specific circuit. They do not all work with every receptor. This is a complicated subject to try to explain in a short statement! I have probably confused you by now.
How do three neurons work together?

How do nerve signals travel from nerve to nerve?
in transmitting a nerve signal such as from your hand to your brain, several neurons are involved. Nerve cells can receive and transmit signals.the dendrites of one neuron are close to the axon of another neuron. The point where neurons meet is called a synapse
What transmits a message from one neuron to the next neuron?
Neurotransmitters don't relay messages. They are chemicals released from one neuron that diffuse across the synaptic cleft and bind to postsynaptic receptors on another cell. 'Messages' is a simile that people use to anthropomorphise how neurons work but actually - any message as such, which you might call a thought, is an enormously complex abstraction of millions of these events happening in a close temporal sequence.
What is the difference between what cocaine does at a synapse and what heroin does at a synapse?
Cocaine and heroin don't act on synapses. Heroin acts on the opioid receptors of neurons. Cocain acts primarily on the dopamine receptors. These are different structures on the surface on neuron cells. They work sort of like switches. Chemicals like heroin flip the switch on or off, affecting the behavior of the neuron. This is a very simplified explanation to this question.
Why is conduction at synapses always one way?
We can be thankful that they go in only one direction; otherwise brain activity would be nothing but chaos. Neurotransmission begins at the synapse. At the synapse, only one of the two corresponding neurons has receptor locations that determine whether or not the receiving neuron will fire. The other neuron at the synapse is responsible for producing the neurotransmitters that attach to the receptors. There is sometimes a re-uptake of neurotransmitters when there are no more receptors for them to attach to. Some psychotropic drugs work to inhibit this re-uptake.

How do rat brains work?
All animal brains, including human brains, work in essentially the same way. There are a whole lot of nerve cells, also called neurons, and any given neuron can either fire or not fire. If it fires, it sends a signal down all of its dendrites and axons. Neurons are connected to lots of other neurons in various complicated ways. They also have connections to other parts of the body. Neurons receive sensory information, and send out messages that control muscles. The signals that neurons receive determine whether they fire or not. Impulses can also pass or fail to pass from one neuron to another, across a small gap called a synapse, depending upon the amount of neurotransmitters in the synapse. Those are the variables. Together, they create a complex data processing system.
How does a neurone work?
they send electrical pulses down the axon to the next neuron.
How do you get IV characteristic of neuron?

How do you air up tires on a cannondale synapse bicycle?
Depends on what valves your tubes are equipped with. See link below for descriptions and how they work
What happens if motor neurons are damaged?
Motor neuron involve the muscles. If they are damaged, then the muscle that they are connected to will not work.
