What is this?
Imagine your body's cells as tiny houses. A sodium channel is like a special, tiny door found in the walls of these houses. It opens and closes to let tiny salty particles, called sodium ions, rush in and out, which is super important for sending messages in your nerves and making your muscles move!
Key Parts to Explore
Central Pore
This is the narrow tunnel right in the middle where sodium particles travel through the channel.
Activation Gate
This part acts like a tiny door that opens to let sodium ions into the cell when it gets a signal.
Inactivation Gate
This second door quickly closes after the first one opens, stopping too many sodium ions from rushing in at once.
Voltage Sensor
This special part senses electrical changes around the cell and tells the gates when to open or close.
