Neurotransmitters. There are several hundred different neurotransmitters used by different types of nerves in different parts of the body, a few are:
- acetylcholine
- dopamine
- serotonin
- glutamate
- aspartate
- D-serine
- γ-aminobutyric acid (GABA)
- glycine
- nitric oxide (NO)
- carbon monoxide (CO)
- hydrogen sulfide (H2S)
- norepinephrine
- epinephrine (adrenaline)
- histamine
- phenethylamine
- N-methylphenethylamine
- tyramine
- 3-iodothyronamine
- octopamine
- tryptamine
- somatostatin
- substance P
- cocaine and amphetamine regulated transcript, opioid peptides[9]
- adenosine triphosphate (ATP)
- adenosine
- anandamide
- β-endorphin
- vasopressin
- dynorphin
- oxytocin
- etc.

What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
How does an impulse cross a synape?
An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.
What can cause synapse to not function correctly?
An abnormally thin dendritic spine can yield poor neural impulse conduction; and drugs like LSD which mimic neurotransmitters may "clog" receptors & cause continued activation, I think. I suspect there could also be problems with the PRODUCTION of neurotransmitters or with the conveyance of vesicles containing NT to the synapse. Synapses are spaces or junctions between two neurons. The principle of synapse works on mechanism of neuro-transmitters and neuro-inhibitors. When a nerve impulse reaches the end of one neuron to travel to the next one, at that moment acetylcholine is produced in the synapse. Acetyl choline being a neurotransmitter helps to transmit the nerve impulse. Right after the nerve impulse has passed through the synapse, a neuroinhibitor such as cholinesterase si produced to stop the action of acetylcholine. At a particular synapse, these two chemicals are produced at a very high rate. This is how a nerve impulse works. But suppose if the production of these two chemicals is affected, the synapse will not function properly.
What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
How does the impulse jump the synapse?
Chemical diffusion
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
What carries an impulse across a synapse to a muscle?
neurons?
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
Can you briefly describe the events that occur when a nerve impulse arrived at a synapse?
A synapse is a junction where two nerves meets. when action potential reaches a synapse, the pores open allowing an afflux of calcium ions into presynaptic terminal. this causes neuro transmitters to be released and cross over the synaptic cleft to attach to receptors in the post synaptic membrane and allow impulse to pass.
On which direction does an impulse go across a synapse?
axon to dendrite
What structures cross the synapse to generate the next impulse?
Neurotransmitters.
