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

Edit: Another crackpot link removed.

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:

I am familiar with voltage gated calcium channels and their role in the process of action potential. Voltage gated calcium channels are specialized proteins found in the cell membrane of neurons. They open and close in response to changes in the electrical potential across the cell membrane, allowing calcium ions to flow into the cell.

During an action potential, there is a sudden change in the electrical potential of the cell membrane. This change triggers the opening of voltage gated calcium channels, allowing calcium ions to enter the cell. The influx of calcium ions then triggers the release of neurotransmitters, which are chemical messengers that allow neurons to communicate with each other.

In terms of calcium ion recycling, there are a few mechanisms that ensure proper levels of calcium ions in the cell. One is the activity of calcium pumps, which actively transport calcium ions out of the cell. Another is the activity of calcium-binding proteins, which bind to excess calcium ions and help regulate their levels.

There are many resources available on voltage gated calcium channels and their role in action potential. I suggest looking into textbooks or scientific articles on neuroscience or cellular biology. You can also consult with a neuroscientist or attend a seminar or conference on the topic. I hope this helps and I wish you luck in your research.
