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).
thin filaments slide past thick filaments towards the M line. When a skeletal muscle fiber contracts: the H bands and I bands get smaller. ; the zones of overlap get larger.; the Z lines get closer together.; the width of the A band remains constant. A muscle cell experiencing resting membrane potential is.
