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.
This area is called the synapse or synaptic cleft. Neurotransmitters from the presynaptic membrane (tip of the axon of the neuron sending the signal) are released via exocyt â¦ osis from the neuron.hen a signal reaches the end of a neuron it releases neurotransmitters into the synapse where they bind to receptors to release the second messenger into the next neuron.
