HELP - voltage gated calcium channels

junk0

Referring to following video, I would like to know more about voltage gated calcium channels, will this process called action potential? How do Calcium ion recycle during this process?

I can find a lot of materials on action potential for Na+/K+ pump along axon, but not much materials talking about calcium channels.

Does anyone have any suggestions?
Thansk in advance for any suggestions

When the action potential arrives at the presynaptic terminal, it causes calcium entry into the terminal. The calcium is buffered, then extruded. Some free articles on the extrusion mechanisms (eg. Na⁺/Ca²⁺ exchanger, Ca²⁺-ATPase) are:
