Right, Face From front to. There was a slight increase 4. What was the effect of lidocaine on eliciting an action potential? In testing the effects of ether, there will be a nerve that will be stimulated. When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. The experiment is to see if ether has any permanent alteration in neural response of the nerve.

Acetylcholine, Motor unit, Motor unit recruitment 1052 Words 4 Pages. A: Increasing the extracellular potassium reduces the steepness of the concentration gradient and so less potassium diffuses out of the neuron. Because depolarization is the shift in electrical potential across a plasma membrane toward 0 to mV and action potential is a rapid voltage change in which a plasma membrane briefly reverses polarity.
