Describe how the EMG signal (a voltage) arises from muscle activity

Sagot :

Answer: The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation). ... EMG signal acquires noise while traveling through different tissues. EMG signals are recorded by placing electrodes close to the muscle groups. When the muscle is activated, the length of the muscle decreases and the muscle, skin and electrodes move with respect to one another. At that time, the electrodes will show some movement artifacts

Explanation:

EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

What do you mean by EMG signals?

EMG signals may be defined as a biomedical signal that estimates electrical currents provoked in muscles during their contraction illustrating neuromuscular activities.

When the muscle is stimulated for any mechanism, the length of the muscle declines, which leads to the muscle, skin, and electrodes moving with regard to one another.

The EMG signals always arise from the electrical activity of the muscle fibers which are stimulated during the time of contraction.

Therefore, EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.
