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 motor neuron is considered the presynaptic cell and the skeletal muscle is the postsynaptic cell. For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in. the hyperpolarization of the neuron.
