Bang Goes The Nerve Cell
a: Neurotransmitter vesicles ~
b: battery of fireworks
What: "Loaded with the neurotransmitter acetylcholine, the vesicles are like a battery of fireworks poised to launch a neurotransmitter barrage into the synaptic cleft - where this amplified signal will in turn energize the adjacent muscle fiber. In the last step, what biologists call a "fusion event," the calcium ions trigger some of the vesicles to fuse with the cell membrane and open outward, allowing their payload to escape."
