Characteristics of a neurotransmitter include its synthesis in the neuron, concentration in membrane-enclosed vesicles at presynaptic terminals, release by neuron terminal depolarization, induced activity at the postsynaptic terminal as a consequence of receptor binding, and removal from the synapse to terminate this effect. Nitric oxide was identified as a biological intercellular messenger just over 20 years ago, and its presence and potential importance in the nervous system was immediately noted.

Med andra ord: neurotransmittorer tillåter anslutningen som en neurons axon upprättar med dendriten från en annan neuron, vilket genererar synapsen.

Structure: Neurons are composed of dendrites, cell body with organelles and axon. Neurotransmitters are molecules stored inside vesicles. Some neurotransmitters act by making the neuron more negatively charged so less likely to fire. This is an inhibitory effect.

A neurotransmitter can influence neurons in one of three ways: it can excite, inhibit, or modulate them. Excitatory neurotransmitters – these types have an excitatory/stimulating effect on the neurons.

2020-03-01 · Neurotransmitters are made in the cell body of the neuron and then transported down the axon to the axon terminal. Neurotransmitters are released from the axon terminal when their vesicles "fuse" with the membrane of the axon terminal, spilling the neurotransmitter into the synaptic cleft.
