context: Neurotransmitters are contained in synaptic vesicles of neurons. When stimulation is transmitted to nerve cells, calcium ion channels are opened before neuronal synapses, and calcium is introduced into the neurons to move synaptic vesicles into the cell membranes of the neurons. The endoplasmic reticulum that has migrated to the cell membrane releases neurotransmitters into the synapse by extracellular outflow from the end of the axon. The released neurotransmitter binds to the receptor on the cell membrane after synapse and changes the permeability of the cell after synapse. If the cation channel is opened and the cation enters the neuron, the neuron depolarizes to deliver the excitatory nerve, and if the anion channel is opened, the neuron is hyperpolarized to inhibit neurotransmission.
