Neurotransmitters. There are several hundred different neurotransmitters used by different types of nerves in different parts of the body, a few are:
Neurotransmitters are chemicals that are released to transmit signals across the synapse. They are released at the presynaptic terminal and travel across the synaptic cleft.
A neurotransmitter called: Acetycholine.
norepinephrine

Hormones.
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.
synapse is that junction through which impulse can be transmitted from one neuron to another.
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.
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.
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
Chemical diffusion
It is most definitely a synapse.
neurons?
The impulse has to cross over a synapse to another neuron or an effector.
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.
