What Molecules of what substances are stored in synaptic terminals?

Synaptic terminals store neurotransmitter molecules, which are essential for communication between neurons. Common neurotransmitters include acetylcholine, dopamine, serotonin, and glutamate. These molecules are released into the synaptic cleft during synaptic transmission, facilitating the transmission of signals across the synapse. Additionally, some terminals may store neuropeptides, which also play roles in modulating synaptic activity.
