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).
Typical values for the concentrations of Na + , K + , and Cl-in the cell water of a muscle cell and in the extracellular fluid of a typical non-marine vertebrate (like you and me) is seen in the diagram below: The resting membrane potential is about 90 mV (inside negative relative to outside).
