What is Conduction along membrane is dependent on all of the following EXCEPT: March 2013 and explain in detail?
Ans. C i.e. Fe2+ A decrease in extracellular Ca2+ concentration increases the excitability of nerve and muscle cells by decreasing the amount of depolarization necessary to initiate the changes in the Na+ and K+ conductance that produce the action potential. Conversely, an increase in extracellular Ca2+ concentration can stabilize the membrane by decreasing excitability.
