Question

Brett ate poisonous wild mushroom, which partially paralyzed his motor unit. his doctor performed an emg test on him and the emg trace is shown above. predict what normal emg from brett could look like?

Answer 1

Normal EMG should have a larger amplitude because inhibition of the motor unit would lead to less electric signals being generated.
Given that Brett ate a poisonous wild mushroom, his amplitude will be lower since his motor unit has been partially paralyzed. This means that electric signals cannot be properly generated in his body, thus the lower amplitude in the EMG.
