But if I remember my Nernst Potential formulas
the primary contributors to the trans-membrane potential are Na+, K+, and Ca++ as Cl- mostly is maintained in equilibrium by passive diffusion, if I recall, it is the concentration gradient that is important in proper maintenance of the trans-membrane potential
As well as the integrety of the
Na+/K+ pump and the Ca++ transport pump

Your missing my point. There’s sodium chloride in ketchup/catsup, sodium citrate & disodium phosphate among the ingredients in Royal orange gelatin, sodium bicrbonate & sodium aluminum sulfate among the ingredients in Davis Baking Powder, etc. My point was that sodium is in a lot of stuff besides table salt.
Hyponatremia means low blood sodium. Hypokalemia means low blood potassium.
Here’s the Stedman’s Medical Dictionary definition of hyponatremia: Abnormally low concentrations of sodium ions in the circulating blood.
