Chemical synapses

WebAug 7, 2024 · A chemical synapse is a biological structure between two neurons or between a neuron and a nonneuronal cell that allows them to interact through chemical messengers. Neurotransmitters are the chemical messengers that carry messages between neurons. Synaptic vesicles are tiny vesicles that generate and package neurotransmitters. Here is a summary of the sequence of events that take place in synaptic transmission from a presynaptic neuron to a postsynaptic cell. Each step is explained in more detail below. Note that with the exception of the final step, the entire process may run only a few hundred microseconds, in the fastest synapses. 1. The process begins with a wave of electrochemical excitation called an action potential travelin…
