What is the meaning of neuro transmitters?

Answer 1

Neurotransmitters are chemical messengers that are used by neurons (nerve cells) to relay motor and sensory information. They are released into the synaptic cleft, where the neurotransmitters are then diffused into the body, and then any remaining amounts are re-absorbed (re-uptake) by a neighboring dendrite.

So just remember, neurotransmitters are chemical messengers for neurons.

Answer 2

A neurotransmitter is a chemical that is used to relay signals between a neuron and another cell. There are three classes of neurotransmitters, which are amino acids, which are very prevlanet throughout the nervous system, peptides, which are usually used to process signals to other parts of the body, for example the digestive tract, and monoamines, which are what many people think of when one mentions neurotransmitters. These include such major molecules as dopamine, norepinephrine, and serotonin.
