Synaptic vesicles contain thousands of neurotransmitter. The  neurotransmitters are packed into a small membrane bound synaptic  vesicles. There are thousands of neurotransm â¦ itter molecules.
There are both small and large vesicles. Small vesicles are produced by the Golgi apparatus located in the soma and transported down the axon via current flow in the cytoplasm (fluid inside the cell). Small vesicles store neurotransmitters. In some neurons, larger vesicles are also found in smaller quantity. These large vesicles store neuropeptides or neuromodulators such as the endorphins. The positively charged ion, calcium (Ca+2), is essential to synaptic transmission.
