1. In addition to measuring muscle contraction and neurotransmitter release, it is also possible to use electrodes to measure the conduction of action potentials along a motor neuron. Given the mechanism of action of muse senores, predict what effect each of them would have had on the conduMion of action potentials along the motor neuron In this experiment. Remember to justify your answer. (1.5 marks)
