I’m referring to the electricity that is involved with the heart beating and brain signals. How does it get into us to begin with when we are a fetus, and how does it keep being produced?
In: Biology
It is not “electricity” exactly – it is a cross-membrane potential. That is a difference in charge which is kept separate by a cell membrane. It is established by a high concentration of sodium on one side of the membrane, and potassium on the other. Those concentrations are created and maintained by little sodium and potassium “pumps” in the membrane itself. That’s what I remember anyway….
