THE TOPIC THAT GOT ON MY NERVES AMTULL REHMAN

In the past the nervous system and everything related fascinated me and really excited me. Therefore, I was very excited to learn about this lesson as well. It was all going very well until we started learning about the electrical nature of neurons. I am not the best at physics and find concepts like electricity and voltage very challenging. This lesson talks about how nerve impulses involve changes in the amount of electric charge across a cell’s plasma membrane. Right off the bat the concept was very complicated. It talked about a membrane potential and how the action potential travels down an axon. I have studied this topic thoroughly multiple times. However, I always get confused how the action potential is triggered. I see that it is triggered when the threshold potential is reached but I do not understand how the threshold potential is reached. Furthermore, I do not understand how the action potential moves down the axon. Because I do not fully understand charges and voltage it is difficult for me to understand
