Guest guest Posted February 3, 2012 Report Share Posted February 3, 2012 Resting membrane potential is when the nerve is not conducting impulse... It is at rest....it is in polarised state then.....that means it has a negative membrane potential of -70 as compared to e.c.f...

Can any one explain about resting membrane potential and active membrane potential? Is there any difference between cardiac cell and neurone? What is inside cell is it NA or K Many thanks Balsam Sent from my iPad Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 3, 2012 Report Share Posted February 3, 2012 At rest bot Na and k are there inside the cell buttt there is higher conc of potassium inside...as compared to outside..so wen the an impulse is generated the sodium ions move to the cell via the From: Balsam_Majid <balsam_majid@...>; To: < >; Subject: Membrane potential Sent: Fri, Feb 3, 2012 4:07:28 PM Hi ...

Guest guest Posted February 3, 2012 Report Share Posted February 3, 2012 Hi Balsam, The inside of a cell is negatively charged when compared to outside while at rest.This potential difference is called resting membrane potential. When a stimulus occurs,there will be a rapid change in the membrane potential during which the membrane rapidly depolarises and repolarises. This is action potential. The concentration of Na is more outside the cell.K is more inside the cell. In cardiac cells,action potential results in contraction,while in neurons,intercellular communication occurs. hope that helps. regards sajitha.
