Neurotransmitters are formed in a presynaptic neuron and stored in small membrane-bound sacks, called vesicles, inside this neuron. When this neuron is activated, these intracellular vesicles fuse with the cell membrane and release their contents into the synapse, a process called exocytosis.
Neurotransmitter release from presynaptic nerve terminals is a central component of synaptic transmission, the main process by which neurons communicate with each other and with target cells. Neurotransmitter is packaged inside small vesicles in the presynaptic nerve terminal.
