What are two variables that influence how much electrical activity is recorded by the electrodes during electromyography?

Question

Quizplus · Accepted Answer

The size and number of muscle fibers as well as the distance between them can influence the amount of electrical activity recorded by the electrodes during electromyography. The position of the ground electrode also plays a role, but this is not one of the options in the question. The type of electrode and percentage body fat of the patient as well as muscle length can also affect EMG readings, but they are not the most significant variables in this context.
