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 Synapse. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons.The synapse consists of: 1  a presynaptic ending that contains neurotransmitters, mitochondria and other cell organelles. 2  a postsynaptic ending that contains receptor sites for neurotransmitters.endrites bring information to the cell body and axons take information away from the cell body.
