Muscle Contraction In an experiment, the strength of a neural stimulus and the resulting muscle contraction are compared. single motor neuron that synapses with one muscle fibre observed in this experiment. One end of the muscle fibre is attached to a mass. The following data were obtained from the experiment. Analyze the data and answer the following questions. Number of Trials Strength of Stimulus (mV) Mass Lifted by Muscle Contraction (g) 1 20 2 40 60 50 4 80 50 5 100 Not Tested 120 50 "note that the voltage applied is positive in order to raise potential from resting to threshold
