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 Potential of the Nerve Cell. Critical to the function of the nerve cell, the cell membrane maintains intracellular conditions that differ from those of the extracellular environment. There is an excess of negative ions inside the cell membrane and an excess of positive ions outside (middle of Figure 1).
