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.
The neurotransmitters are released into the space between the end of an axon and the tip of a dendrite from another neuron. This space is called a synapse (pronounced SIN-aps). The neurotransmitters travel the short distance through the synapse to the dendrite.
