Detailed explanation-1: -Influx of calcium ions into the presynaptic nerve terminal causes vesicles (loaded with neurotransmitters) migrate toward the presynaptic membrane. Then, the vesicle and membrane fuse, and neurotransmitter is released into the synaptic cleft by exocytosis.
Detailed explanation-2: -Synapses connect neurons in the brain to neurons in the rest of the body and from those neurons to the muscles. This is how the intention to move our arm, for example, translates into the muscles of the arm actually moving.
Detailed explanation-3: -Once they have been released and have bound to postsynaptic receptors, neurotransmitter molecules are immediately deactivated by enzymes in the synaptic cleft; they are also taken up by receptors in the presynaptic membrane and recycled.
