Neurology question: Signals moving along nerve cells.
(if this is the wrong forum, please point me to a better one)
First, I would like to clear-up my own understanding.
(a) Within nerve cells - As I understand it, signals move from one end of the cell to the other via electric pulses.
Is that correct?
(b) between nerve cells - As I understand it, Molecules of neurochemicals carry the signal across the gap between cells.
Is that correct?
Neurology question: Signals part 2
What happens to these molecules of neurochemicals, after they have carried their signal across the gap between nerve cells?
Are the neurochemicals absorbed by the receiving cell?
Are they retained by the receiving cell? Do they build-up?
Do they dissolve, or break-down, or get washed away?
Do they return to the originating cell?
Do they get re-used? Return to the original cell when a signal goes back the other way?
I have never heard an explanation of what happens next, to the neurochemicals. As if they've done their job, forget about em.
I think that is a mistake.
I'll explain why, after I improve my own understanding.
Thank you for your help.
