Have you ever heard of an electromyograph?

Yeah, isn't that the device that measures muscle activity?

Exactly! It helps diagnose neuromuscular disorders.

Root Explanation

Electromyograph → It is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "myo-" (from Greek "mus", meaning muscle) and "graph" (from Greek "grapho", meaning to write). The word refers to a device that writes or records the electrical activity of muscles.

Memory Tip

Think of 'electricity' ('electro-') related to 'muscles' ('myo-') being 'written down' ('graph') — that's how an electromyograph records muscle activity.
