Quizplus · Accepted Answer

Electromyography involves placing small needles into a muscle to record its electrical activity at rest and during contraction. It is used to provide information in disorders of muscles, peripheral nerves, and the neuromuscular junction. The word breaks down into the suffix -graphy meaning process of recording, and the two root/combining forms: electr/o- meaning electricity and -my/o- meaning muscle.
