Flashcards in Voltage-gated Ion Channel Deck (13):
Where is the voltage-gated ion channels,
found in the axon hillock
- nodes of ranvier
ONLY TWO TYPES of ions
Axon Hillock says
If you can bring me enough EPSP in comparison to IPSP, to bring the membrane potential to -55, ill initiate an action potential
VG (Na+) Channels
Opens at -55mV
Clases at +30mV
VG (K+) Channels
Opens at +30
At -55mV, the VG _________.
(Na+) channels open
Na+ ______, pours into cell until the inside voltage becomes ______.
Stops because the ______, then the axon hillock concentration is ______, which leads to neurotransmitter release.
Some of it goes to the next ____, brings it up to______, causing this __.
gates to open
