WebAn electrical nerve impulse travels along the axon of the first neuron (presynaptic neuron). When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called... WebMost of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells.

WebSynaptic transmission is the key process in the integrative action of the nervous system. Synaptic transmission is the process at synapses by which a chemical signal (a transmitter) is released from one neuron and diffuses to other neurons or target cells where it generates a signal which excites, inhibits or modulates cellular activity.

WebSynaptic vesicles are only found in presynaptic 1ci) Dopamine is a neurotransmitter. Production of too much dopamine is associated with schizophrenia.
