Touching a hot stove is just one thing that causes nerve impulses to occur within the body lets see what happens.
OUCH!
Inside the cell
If more negative attitude people line up on a particular side of the classroom the overall attitude of that side is negative.
Outside the cell
Not exactly like a cell but at rest there is a high number of sodium ions outside the membrane meaning the internal charge is negative.
If positive attitude people move from outside to inside where there is already negative attitude people the overall attitude now shifts to positive.
Inside the cell
Outside the cell
This is like when Depolarization occurs and the gated sodium channel is opened and now the inside is positively charged.
If positive attitude people move out of the inside, that side of the cell side becomes more negative.
Inside the cell
When channel doors switch, the potassium channel opens. Potassium ions move outside causing the inside of the cell to become more negative again. This is called re-polarization
Outside the cell
After the pump returns to rest using active transport, what happens next is when the action potential reaches the end of the axon at the axon terminal
This could be similar to holding students in school and not letting them leave while they are all in the same space. Students here would represent neurotransmitters.
When students are released to buses, it is similar to when neurotransmitters are released to attach to receptors.
After attaching the action potential spreads to the next cell which is like when students go home and share the information from school at their own homes.
