   Neurotransmitter
   [See firstly neurotransmission.] The contents of the synaptic vesicles released from the pre-synaptic neuron into the synaptic cleft. These chemicals induce a post-synaptic potential in the receiving neuron.

5. 
   neurotransmitter
   Neurotransmitters are molecules that are used to carry signals from one neuron to another. One neuron releases the neurotransmitter near another neuron's receptors. The neurotransmitter diffuses across the gap between the neurons and locks into a receptor site on the surface of the downstream neuron. This induces a change in the downstream neuron.

   Neurotransmitter
   A chemical mediator released from nerve terminals in response to nerve stimulation and which binds to receptors which are on the surface of other nerve cells. There are a number of different classes of neurotransmitters as well as many different receptor types and subtypes.

    Neurotransmitter
    Neurotransmitter: A chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve, muscle, organ, or other tissue. A neurotransmitter is a messenger of neurologic information from one cell to another.

13. 
    neurotransmitter
    A substance found in chemical synapses that is released from the presynaptic terminal in response to depolarization by an action potential, diffuses across the synaptic cleft, and binds a ligand-gated ion channel on the postsynaptic cell. This alters the resting potential of the postsynaptic cell, and thus its excitability. Examples: acetylcholine, GABA, noradrenaline, serotonin, dopamine. See Table N1.

    Neurotransmitter
    `Neurotransmitters` are chemicals that are used to relay, amplify and modulate signals between a neuron and another cell. According to the prevailing beliefs of the 1960s, a chemical can be classified as a neurotransmitter if it meets the following conditions: * There are precursors and/or synthesis enzymes located in the presynaptic neuron; * The chemical must be present in the presynaptic element * It is available in sufficient quantity in the ...

    neurotransmitter
    The arrival of a nerve impulse stimulates the release of neurotransmitters from vesicles. They pass across the synapse and open channels in the target cell. Charged particles can then enter and trigger a second impulse. A chemical that mediates the transmission of a nerve impulse across the syna...

    neurotransmitter
    neurotransmitter, chemical that transmits information across the junction (synapse) that separates one nerve cell (neuron) from another nerve cell or a muscle. Neurotransmitters are stored in the nerve cell's bulbous end (axon). When an electrical impulse traveling along the nerve reaches the axon, ...
