When someone is displaying signs of a muscle or nerve dysfunction, a doctor may order an EMG. These electrical signals are converted into diagrams or numbers by an EMG, helping doctors provide medical advice. They relay electrical impulses that induce contraction and relaxation of muscles. Such nerve cells are referred to as motor neurons. Electromyography (EMG) is a medical test that involves nerve conduction study of the muscles and the nerve cells that regulate them in terms of wellness.
