They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone.
There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.

What do neurotransmitters open?
Neurotransmitters act on synapses.
What OPEN do?
Neurotransmitters act on synapses.
Have amino acid neurotransmitters not been found yet although a variety of molecules act as neurotransmitters?
False
What hormones act as hormones and neurotransmitters?
Epinephrine & Norepinephrine (NE)
What are retrograde neurotransmitters?
Retrograde neurotransmitters are neurotransmitters that are released from the postsynaptic neuron and act on receptors of the presynaptic neuron. They help modulate the strength of synaptic transmission and play a role in feedback regulation of neurotransmitter release. Examples include endocannabinoids and nitric oxide.
Do betalains act as neurotransmitters?
There is no documentation on it. I am also working on betalains but till date I have not come across neurotransmitting activity of betalains.
What are the examples of neurtransmitters?
Examples of neurotransmitters are: acetylcholine, dopamine, norepinephrine, and epinephrine. They also act as hormones but basically they are neurotransmitters that helps send nerve impulses to the brain through axons so that a certain action can be done by a muscle or gland.
Inhibitory neurotransmitters of the CNS act by opening gates?
Inhibitory neurotransmitters in the CNS, such as GABA and glycine, act by opening chloride ion channels in the postsynaptic neuron. This influx of chloride ions hyperpolarizes the neuron, making it less likely to depolarize and generate an action potential, thus inhibiting neuronal activity.
What are neuro transmitters?
The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!
How do drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
Which structure in the body releases neurotransmitters?
Neurons release neurotransmitters.
What neurotransmitters are amino acids?
define amino acids in neurotransmitters
