Document Summary

The force on sodium ions is to move into the cell, and the force on potassium ions is to move out of the cell. At the resting membrane potential, the membrane is most permeable to ________, which moves ________ the cell due to its electrochemical gradient. potassium : out of. If, under resting conditions, the membrane is much more permeable to sodium than potassium, what would happen to the resting membrane potential? approach sodium"s equilibrium potential. If we apply an electrical stimulus to a muscle cell to cause it to contract, the magnitude of that stimulus must be strong enough to reach a critical value that is essential in initiating the process of contraction. This critical value is known as __________. threshold. A change in a cell"s membrane potential, such that it becomes more negative, is referred to as a ________. hyperpolarization.
