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 main ions that determine the resting membrane potential are potassium, sodium, and chloride. The logic for how they determine the membrane potential is very similar, so I will explain how potassium contributes (it has the greatest conductance at rest).
