What is the difference between a neuromodulator and a neurotransmitter?
Wiki User
∙ 12y ago
A neuromodulator modifies or makes more or less efficient the synaptic action of a neurotransmitter. Whereas a neurotransmitters work as chemicals released from terminal vesicles into synaptic clefts to receptors depolarizing the next neuron and initiates an electrical charge.

What is the best definition for a neurotransmitter?
The chemical messenger of the body is a neurotransmitter. They are chemicals that carry signals between neurons or from neurons to muscles. In the synaptic cleft, impulses are exchanged between two neurons.
What kinds of compounds in the body transmit impulses between nerve and muscle cells?
a Neurotransmitter
What neurotransmitter might the parietal lobe use and why?
The neurotransmitter used by the parietal lobe is acetylcholine.
What is the location of the vesicles that store neurotransmitter?
Synapses are located throughout the nervous system. A synapse is a sort of 'relay station' where a message, in the form a a chemical neurotransmitter, is passed on between one neuron (nerve fibre) & the next, or between a neuron & the muscle or gland the message is aimed at.
Anagonist defininition in human anatomy?
A mimic of a neurotransmitter. Not the exact neurotransmitter, but works in the same way.
Compound that influences a postsynaptic cell's response to a neurotransmitter?
neuromodulator
What is the difference between presynaptic and postsynaptic neurons?
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
What is a good example of a neuromodulator?
Acetylcholine
What does octopamine do to the body?
In invertebrates, it speeds up the heart rate, and acts as a neurohormone, a neuromodulator and a neurotransmitter. It is one of the many G-protein coupled receptors. Additionally, it inhibits and activates adenylyl cyclase and phospholipase C, and couples chloride channels
What neurotransmitter is released at the motor end plates by axon terminals?
The accepted terminology is either neurotransmitter or neuromodulator. The compounds are epinephrine, ACh, norepiniphrine, GABA, glycine, ATP , ADP, adenosine, glutamate, aspartate, substance P, Neuropeptide Y, LHRH and probably 2 dozen others. In addition NO (nitric oxide) acts as a neuronal released modulator (albeit not by synaptic release).
Function of neurotransmitter?
To transmit a signal between neurons.
What is the best definition for a neurotransmitter?
The chemical messenger of the body is a neurotransmitter. They are chemicals that carry signals between neurons or from neurons to muscles. In the synaptic cleft, impulses are exchanged between two neurons.
What is the chemical produced between nerve cells?
a neurotransmitter called acetylcholine (ACh) is produced between nerve cells. This neurotransmitter carries the signal (in chemical form) at the synaptic junction.
What is the chemical secreted into the gap between neurons at the synapse?
The answer is NEUROTRANSMITTER.
What neurotransmitter between muscle cells and the nervous system cells is?
norepinephrine
What is the difference between Neuron and synapse?
A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the receiving neuron. (A neurotransmitter is a chemical messenger.)
What is the difference between dopamine and dobutamine?
Dobutamine is a drug that acts on the sympathetic nervous system. Physicians use it to treat heart failure and cardiogenic shock. Dopamine is a neurotransmitter that our bodies produce in order to send signals between brain cells.
