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
