Neurophysiology Flashcards
1
Q
Threshold potential is…
A
60mV
2
Q
Threshold potential stimulates the opening of…
A
Voltage gated channels
3
Q
What type of ion channel is found in the axon membrane?
A
Voltage gated
4
Q
Why does action potential happen at the axon hillock?
A
There are no gated channels and the dendrites and cell body
5
Q
Why do we have to get the membrane to -60 at the axon hillock?
A
Because thats where we see a really high density of voltage gated channels
6
Q
Where does action potential first happen?
A
Axon hillock
7
Q
Where does action potential next happen?
A
Initial segment of the axon
8
Q
Beginning of the axon
A
Initial segment of the axon
9
Q
A
