1. |
Stimulus causes the first ion channel to open in the dendrite region |
|
|
2. |
Positive ions will begin to enter into the ICF |
|
|
3. |
The positive ions that enter the ICF in the region of the dendrite will diffuse to the axon region |
|
|
a. |
The transmembrane potential begins at -70mV |
|
|
b. |
Positive ions enter due to the stimulus |
|
|
c. |
These positive ions begin to diffuse to the axon hillock region |
|
|
d. |
These ions will cause a voltage change as they diffuse. |
|
|
e. |
As soon as the voltage reaches about -60 mV, the voltage channels in the axon open up. These voltage channels are sodium channels |
|
|
4. |
This causes a flood of sodium ions into the axon, which is called depolarization |
|
|
5. |
These sodium ions will then cause the next voltage channel to open |
|
|
6. |
This results in another flood of sodium ions into the axon |
