Membrane Potentials Flashcards
1
Q
what does it mean if the ion channel is ligand-gated
A
where a neurotransmitter binds to the receptor to open or close the channel
2
Q
what does it mean if the ion channel is ion-gated
A
changes in membrane potential will open or close ion channels
3
Q
what is a patch clamp
A
an electrophysiology technique used to measure the equilibrium potentials to then predict which ions generate a particular response
4
Q
what does myelination do to action potentials
A
they speed it up
5
Q
what is conductance (siemens - G) opposite to
A
resistance
6
Q
what is capacitance (Farads - F)
A
the ability to storer charge
7
Q
in patch clamp, when the voltage increases, what does it mean
A
it means that the resistance has increase and that the membrane channels are closed
