Ok. This video fails to show the role of Calcium voltage-gated channels. The action potential does not trigger the opening of vesicles; it opens the Ca voltage-gated channels, allowing Ca to enter the presynaptic cell. From the Ca, a protein on the Ca tells the vesicles w/ the neurotransmitters to exocytose! It's not the impulse! It's the calcium!

What about the Voltage-gated calcium channels?!

HELL YEAH CLATHRIN COATED PITS! What a crude description this video includes. The sponatneous assembly and disassembly of clathrin coated vesicles in cells deserves a more detailed representation.
