Which term refers to the recording of the electrical activity of the muscles?

Explanation:
Recording the electrical activity of muscles is described by electromyography, and the actual tracing you observe is called an electromyogram. The -gram suffix signals a recording. The other terms refer to different things: electrocardiogram records the heart’s electrical activity, endarterectomy is a surgical procedure to remove plaque from an artery, and encephalitis is brain inflammation. Therefore electromyogram is the correct term for the recording of muscle electrical activity.
