When extracellular potassium is increased from 4 meq to 10 meq what will happen
If the extracellular potassium concentration surrounding a myocyte increases, then the potassiumgradient accross the cell membrane decreases, and therefore the resting membrane potential will become more positive. There fore increase in the conduction of pottasium increases Similarly, if extracellular potassiumdecreases, the resting membrane potential will be more negative. Ref guyton and hall textbook of medical physiology 12/e p59
Resting membrane potential becomes more negative
Increase in conductance of sodium
Increase in conduction of potassium
Na+ K+ ATpase will be stopped
