Post differentials. (a). A post differential may be granted on the basis of conditions of environment which differ substantially from conditions of environment in the continental United States and warrant additional pay as a recruitment and retention incentive.
We will also see that in order for a neuron to generate an action potential, the membrane potential has to depolarize from the resting value of around â70 mV to the threshold value of around â50 mV. A similar situation is also at play in muscle cells (skeletal, cardiac, and smooth).
The Resting Membrane Potential [back to top] 1  K+ pass easily into the cell. 2  Cl- and Na+ have a more difficult time crossing. 3  Negatively charged protein molecules inside the neurone cannot pass the membrane. 4  The Na+K+ATPase pump uses energy to move 3Na+ out for every 2K+ into neuron.
