Guest guest Posted February 23, 2012 Report Share Posted February 23, 2012 Can any one answer these question because i can not find the answer for them. 1. Which ion is most important for nerve endings? HCO3 Mg+2 CO3 Queswtion 2 : which ion intitiates the action potentional Thanks Pearl > > Can any one answer these question because i can not find the answer for them. > 1.

Guest guest Posted February 23, 2012 Report Share Posted February 23, 2012 For q.2 I think it's Ca ion.

Guest guest Posted February 23, 2012 Report Share Posted February 23, 2012 Sorry I was wrong.it's Na who initiates ( depolarization ) and K for repolarization.Sent from my iPhoneOn 23, Ùروری 2012, at 12:21 PM, "pearltooth32" <pearltooth32@...> wrote: Can any one answer these question because i can not find the answer for them. 1.

Guest guest Posted February 25, 2012 Report Share Posted February 25, 2012 hello pearl! the ion necessary for action potential as asked in first question is HCO3. it maintains intercellular nerve potential negative with respect to extracellular. in your second question, the Na+ ion moves inward and causes the action potential.

Guest guest Posted February 26, 2012 Report Share Posted February 26, 2012 I though it was calcium important for nerve endings if third choice is calcium.
